## Class DataFlavor

- java.lang.Object
- - java.awt.datatransfer.DataFlavor

- All Implemented Interfaces:
    Externalizable, Serializable, Cloneable
  Direct Known Subclasses:
    ActivationDataFlavor

      public class DataFlavor
      extends Object
      implements Externalizable, Cloneable

  A `DataFlavor` provides meta information about data. `DataFlavor` is typically used to access data on the clipboard, or during a drag and drop operation.

  An instance of `DataFlavor` encapsulates a content type as defined in RFC 2045 and RFC 2046. A content type is typically referred to as a MIME type.

  A content type consists of a media type (referred to as the primary type), a subtype, and optional parameters. See RFC 2045 for details on the syntax of a MIME type.

  The JRE data transfer implementation interprets the parameter "class" of a MIME type as a representation class. The representation class reflects the class of the object being transferred. In other words, the representation class is the type of object returned by `Transferable.getTransferData(java.awt.datatransfer.DataFlavor)`. For example, the MIME type of `imageFlavor` is `"image/x-java-image;class=java.awt.Image"`, the primary type is `image`, the subtype is `x-java-image`, and the representation class is `java.awt.Image`. When `getTransferData` is invoked with a `DataFlavor` of `imageFlavor`, an instance of `java.awt.Image` is returned. It's important to note that `DataFlavor` does no error checking against the representation class. It is up to consumers of `DataFlavor`, such as `Transferable`, to honor the representation class.
  Note, if you do not specify a representation class when creating a `DataFlavor`, the default representation class is used. See appropriate documentation for `DataFlavor`'s constructors.

  Also, `DataFlavor` instances with the "text" primary MIME type may have a "charset" parameter. Refer to RFC 2046 and `selectBestTextFlavor(java.awt.datatransfer.DataFlavor[])` for details on "text" MIME types and the "charset" parameter.

  Equality of `DataFlavors` is determined by the primary type, subtype, and representation class. Refer to `equals(DataFlavor)` for details. When determining equality, any optional parameters are ignored. For example, the following produces two `DataFlavors` that are considered identical:

         DataFlavor flavor1 = new DataFlavor(Object.class, "X-test/test; class=<java.lang.Object>; foo=bar");
         DataFlavor flavor2 = new DataFlavor(Object.class, "X-test/test; class=<java.lang.Object>; x=y");
         // The following returns true.
         flavor1.equals(flavor2);

  As mentioned, `flavor1` and `flavor2` are considered identical. As such, asking a `Transferable` for either `DataFlavor` returns the same results.

      The `DataFlavor` representing a Java Unicode String class, where:

               representationClass = java.lang.String
               mimeType           = "application/x-java-serialized-object"

    - #### imageFlavor

          public static final DataFlavor imageFlavor

      The `DataFlavor` representing a Java Image class, where:

               representationClass = java.awt.Image
               mimeType            = "image/x-java-image"

    - #### plainTextFlavor

          @Deprecated
          public static final DataFlavor plainTextFlavor

      Deprecated. as of 1.3. Use `DataFlavor.getReaderForText(Transferable)` instead of `Transferable.getTransferData(DataFlavor.plainTextFlavor)`.
      The `DataFlavor` representing plain text with Unicode encoding, where:

               representationClass = InputStream
               mimeType            = "text/plain; charset=unicode"

      This `DataFlavor` has been deprecated because (1) Its representation is an InputStream, an 8-bit based representation, while Unicode is a 16-bit character set; and (2) The charset "unicode" is not well-defined. "unicode" implies a particular platform's implementation of Unicode, not a cross-platform implementation.

    - #### javaSerializedObjectMimeType

    - #### selectBestTextFlavor

          public static final DataFlavor selectBestTextFlavor(DataFlavor[] availableFlavors)

      Selects the best text `DataFlavor` from an array of `DataFlavor`s. Only `DataFlavor.stringFlavor`, and equivalent flavors, and flavors that have a primary MIME type of "text", are considered for selection.

      Flavors are first sorted by their MIME types in the following order:

      - "text/sgml"
      - "text/xml"
      - "text/html"
      - "text/rtf"
      - "text/enriched"
      - "text/richtext"
      - "text/uri-list"
      - "text/tab-separated-values"
      - "text/t140"
      - "text/rfc822-headers"
      - "text/parityfec"
      - "text/directory"
      - "text/css"
      - "text/calendar"
      - "application/x-java-serialized-object"
      - "text/plain"
      - "text/<other>"

      For example, "text/sgml" will be selected over "text/html", and `DataFlavor.stringFlavor` will be chosen over `DataFlavor.plainTextFlavor`.

      If two or more flavors share the best MIME type in the array, then that MIME type will be checked to see if it supports the charset parameter.

      The following MIME types support, or are treated as though they support, the charset parameter:

      - "text/sgml"
      - "text/xml"
      - "text/html"
      - "text/enriched"
      - "text/richtext"
      - "text/uri-list"
      - "text/directory"
      - "text/css"
      - "text/calendar"
      - "application/x-java-serialized-object"
      - "text/plain"
      The following MIME types do not support, or are treated as though they do not support, the charset parameter:
      - "text/rtf"
      - "text/tab-separated-values"
      - "text/t140"
      - "text/rfc822-headers"
      - "text/parityfec"
      For "text/<other>" MIME types, the first time the JRE needs to determine whether the MIME type supports the charset parameter, it will check whether the parameter is explicitly listed in an arbitrarily chosen `DataFlavor` which uses that MIME type. If so, the JRE will assume from that point on that the MIME type supports the charset parameter and will not check again. If the parameter is not explicitly listed, the JRE will assume from that point on that the MIME type does not support the charset parameter and will not check again. Because this check is performed on an arbitrarily chosen `DataFlavor`, developers must ensure that all `DataFlavor`s with a "text/<other>" MIME type specify the charset parameter if it is supported by that MIME type. Developers should never rely on the JRE to substitute the platform's default charset for a "text/<other>" DataFlavor. Failure to adhere to this restriction will lead to undefined behavior.

      If the best MIME type in the array does not support the charset parameter, the flavors which share that MIME type will then be sorted by their representation classes in the following order: `java.io.InputStream`, `java.nio.ByteBuffer`, `[B`, <all others>.

      If two or more flavors share the best representation class, or if no flavor has one of the three specified representations, then one of those flavors will be chosen non-deterministically.

      If the best MIME type in the array does support the charset parameter, the flavors which share that MIME type will then be sorted by their representation classes in the following order: `java.io.Reader`, `java.lang.String`, `java.nio.CharBuffer`, `[C`, <all others>.

      If two or more flavors share the best representation class, and that representation is one of the four explicitly listed, then one of those flavors will be chosen non-deterministically. If, however, no flavor has one of the four specified representations, the flavors will then be sorted by their charsets. Unicode charsets, such as "UTF-16", "UTF-8", "UTF-16BE", "UTF-16LE", and their aliases, are considered best. After them, the platform default charset and its aliases are selected. "US-ASCII" and its aliases are worst. All other charsets are chosen in alphabetical order, but only charsets supported by this implementation of the Java platform will be considered.

      If two or more flavors share the best charset, the flavors will then again be sorted by their representation classes in the following order: `java.io.InputStream`, `java.nio.ByteBuffer`, `[B`, <all others>.

      If two or more flavors share the best representation class, or if no flavor has one of the three specified representations, then one of those flavors will be chosen non-deterministically.

      Parameters:
        `availableFlavors` - an array of available `DataFlavor`s
      Returns:
        the best (highest fidelity) flavor according to the rules specified above, or `null`, if `availableFlavors` is `null`, has zero length, or contains no text flavors

    - #### getReaderForText

          public Reader getReaderForText(Transferable transferable)
                                  throws UnsupportedFlavorException,
                                         IOException

      Gets a Reader for a text flavor, decoded, if necessary, for the expected charset (encoding). The supported representation classes are `java.io.Reader`, `java.lang.String`, `java.nio.CharBuffer`, `[C`, `java.io.InputStream`, `java.nio.ByteBuffer`, and `[B`.

      Because text flavors which do not support the charset parameter are encoded in a non-standard format, this method should not be called for such flavors. However, in order to maintain backward-compatibility, if this method is called for such a flavor, this method will treat the flavor as though it supports the charset parameter and attempt to decode it accordingly. See `selectBestTextFlavor` for a list of text flavors which do not support the charset parameter.

      Parameters:
        `transferable` - the `Transferable` whose data will be requested in this flavor
      Returns:
        a `Reader` to read the `Transferable`'s data
      Throws:
        `IllegalArgumentException` - if the representation class is not one of the seven listed above
        `IllegalArgumentException` - if the `Transferable` has `null` data
        `NullPointerException` - if the `Transferable` is `null`
        `UnsupportedEncodingException` - if this flavor's representation is `java.io.InputStream`, `java.nio.ByteBuffer`, or `[B` and this flavor's encoding is not supported by this implementation of the Java platform
        `UnsupportedFlavorException` - if the `Transferable` does not support this flavor
        `IOException` - if the data cannot be read because of an I/O error

    - #### equals

          public boolean equals(Object o)

      Indicates whether some other object is "equal to" this one.

      The `equals` method implements an equivalence relation on non-null object references:

      - It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`.
      - It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
      - It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
      - It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
      - For any non-null reference value `x`, `x.equals(null)` should return `false`.

      The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

      Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

      The equals comparison for the `DataFlavor` class is implemented as follows: Two `DataFlavor`s are considered equal if and only if their MIME primary type and subtype and representation class are equal. Additionally, if the primary type is "text", the subtype denotes a text flavor which supports the charset parameter, and the representation class is not `java.io.Reader`, `java.lang.String`, `java.nio.CharBuffer`, or `[C`, the `charset` parameter must also be equal. If a charset is not explicitly specified for one or both `DataFlavor`s, the platform default encoding is assumed. See `selectBestTextFlavor` for a list of text flavors which support the charset parameter.

      Overrides:
        `equals` in class `Object`
      Parameters:
        `o` - the `Object` to compare with `this`
      Returns:
        `true` if `that` is equivalent to this `DataFlavor`; `false` otherwise
      See Also:
        `selectBestTextFlavor(java.awt.datatransfer.DataFlavor[])`

    - #### equals

          public boolean equals(DataFlavor that)

      This method has the same behavior as `equals(Object)`. The only difference being that it takes a `DataFlavor` instance as a parameter.
      Parameters:
        `that` - the `DataFlavor` to compare with `this`
      Returns:
        `true` if `that` is equivalent to this `DataFlavor`; `false` otherwise
      See Also:
        `selectBestTextFlavor(java.awt.datatransfer.DataFlavor[])`

    - #### equals

          @Deprecated
          public boolean equals(String s)

      Deprecated. As inconsistent with `hashCode()` contract, use `isMimeTypeEqual(String)` instead.
      Compares only the `mimeType` against the passed in `String` and `representationClass` is not considered in the comparison. If `representationClass` needs to be compared, then `equals(new DataFlavor(s))` may be used.
      Parameters:
        `s` - the `mimeType` to compare.
      Returns:
        true if the String (MimeType) is equal; false otherwise or if `s` is `null`

    - #### hashCode

          public int hashCode()

      Returns hash code for this `DataFlavor`. For two equal `DataFlavor`s, hash codes are equal. For the `String` that matches `DataFlavor.equals(String)`, it is not guaranteed that `DataFlavor`'s hash code is equal to the hash code of the `String`.
      Overrides:
        `hashCode` in class `Object`
      Returns:
        a hash code for this `DataFlavor`
      See Also:
        `Object.equals(java.lang.Object)`, `System.identityHashCode(java.lang.Object)`

    - #### match

          public boolean match(DataFlavor that)

      Identical to `equals(DataFlavor)`.
      Parameters:
        `that` - the `DataFlavor` to compare with `this`
      Returns:
        `true` if `that` is equivalent to this `DataFlavor`; `false` otherwise
      Since:
        1.3
      See Also:
        `selectBestTextFlavor(java.awt.datatransfer.DataFlavor[])`

    - #### isFlavorTextType

          public boolean isFlavorTextType()

      Returns whether this `DataFlavor` is a valid text flavor for this implementation of the Java platform. Only flavors equivalent to `DataFlavor.stringFlavor` and `DataFlavor`s with a primary MIME type of "text" can be valid text flavors.

      If this flavor supports the charset parameter, it must be equivalent to `DataFlavor.stringFlavor`, or its representation must be `java.io.Reader`, `java.lang.String`, `java.nio.CharBuffer`, `[C`, `java.io.InputStream`, `java.nio.ByteBuffer`, or `[B`. If the representation is `java.io.InputStream`, `java.nio.ByteBuffer`, or `[B`, then this flavor's `charset` parameter must be supported by this implementation of the Java platform. If a charset is not specified, then the platform default charset, which is always supported, is assumed.

      If this flavor does not support the charset parameter, its representation must be `java.io.InputStream`, `java.nio.ByteBuffer`, or `[B`.

      See `selectBestTextFlavor` for a list of text flavors which support the charset parameter.

      Returns:
        `true` if this `DataFlavor` is a valid text flavor as described above; `false` otherwise

        `Cloneable`

    - #### normalizeMimeTypeParameter

          @Deprecated
          protected String normalizeMimeTypeParameter(String parameterName,
                                                     String parameterValue)

      Deprecated.
      Called on `DataFlavor` for every MIME Type parameter to allow `DataFlavor` subclasses to handle special parameters like the text/plain `charset` parameters, whose values are case insensitive. (MIME type parameter values are supposed to be case sensitive.

      This method is called for each parameter name/value pair and should return the normalized representation of the `parameterValue`. This method is never invoked by this implementation from 1.1 onwards.

    - #### normalizeMimeType

          @Deprecated
          protected String normalizeMimeType(String mimeType)

      Deprecated.
      Called for each MIME type string to give `DataFlavor` subtypes the opportunity to change how the normalization of MIME types is accomplished. One possible use would be to add default parameter/value pairs in cases where none are present in the MIME type string passed in. This method is never invoked by this implementation from 1.1 onwards.
