## Class Any

- java.lang.Object
- - org.omg.CORBA.Any

- All Implemented Interfaces:
    Serializable, IDLEntity

      public abstract class Any
      extends Object
      implements IDLEntity

  Serves as a container for any data that can be described in IDL or for any IDL primitive type. An `Any` object is used as a component of a `NamedValue` object, which provides information about arguments or return values in requests, and which is used to define name/value pairs in `Context` objects.

  An `Any` object consists of two parts:

  1. a data value
  2. a `TypeCode` object describing the type of the data value contained in the `Any` object. For example, a `TypeCode` object for an array contains a field for the length of the array and a field for the type of elements in the array. (Note that in this case, the second field of the `TypeCode` object is itself a `TypeCode` object.)

  A large part of the `Any` class consists of pairs of methods for inserting values into and extracting values from an `Any` object.

  For a given primitive type X, these methods are:

  `void insert_X(X x)`
    This method allows the insertion of an instance `x` of primitive type `X` into the `value` field of the `Any` object. Note that the method `insert_X` also resets the `Any` object's `type` field if necessary.
  `X extract_X()`
    This method allows the extraction of an instance of type `X` from the `Any` object.

    This method throws the exception `BAD_OPERATION` under two conditions:

    1. the type of the element contained in the `Any` object is not `X`
    2. the method `extract_X` is called before the `value` field of the `Any` object has been set

  There are distinct method pairs for each primitive IDL data type (`insert_long` and `extract_long`, `insert_string` and `extract_string`, and so on).

  The class `Any` also has methods for getting and setting the type code, for testing two `Any` objects for equality, and for reading an `Any` object from a stream or writing it to a stream.

    - #### equal

          public abstract boolean equal(Any a)

      Checks for equality between this `Any` object and the given `Any` object. Two `Any` objects are equal if both their values and type codes are equal.
      Parameters:
        `a` - the `Any` object to test for equality
      Returns:
        `true` if the `Any` objects are equal; `false` otherwise
      See Also:
        `CORBA` package comments for unimplemented features

    - #### type

          public abstract TypeCode type()

      Returns type information for the element contained in this `Any` object.
      Returns:
        the `TypeCode` object containing type information about the value contained in this `Any` object

    - #### type

          public abstract void type(TypeCode t)

      Sets this `Any` object's `type` field to the given `TypeCode` object and clears its value.

      Note that using this method to set the type code wipes out the value if there is one. The method is provided primarily so that the type may be set properly for IDL `out` parameters. Generally, setting the type is done by the `insert_X` methods, which will set the type to X if it is not already set to X.

      Parameters:
        `t` - the `TypeCode` object giving information for the value in this `Any` object

    - #### read_value

          public abstract void read_value(InputStream is,
                        TypeCode t)
                                   throws MARSHAL

      Reads off (unmarshals) the value of an `Any` object from the given input stream using the given typecode.
      Parameters:
        `is` - the `org.omg.CORBA.portable.InputStream` object from which to read the value contained in this `Any` object
        `t` - a `TypeCode` object containing type information about the value to be read
      Throws:
        `MARSHAL` - when the given `TypeCode` object is not consistent with the value that was contained in the input stream

    - #### write_value

          public abstract void write_value(OutputStream os)

      Writes out the value of this `Any` object to the given output stream. If both `typecode` and `value` need to be written, use `create_output_stream()` to create an `OutputStream`, then use `write_any` on the `OutputStream`.

      If this method is called on an `Any` object that has not had a value inserted into its `value` field, it will throw the exception `java.lang.NullPointerException`.

      Parameters:
        `os` - the `org.omg.CORBA.portable.OutputStream` object into which to marshal the value of this `Any` object

    - #### create_output_stream

          public abstract InputStream create_input_stream()

      Creates an input stream from which this `Any` object's value can be unmarshalled.
