javax.swing.text

## Class TabSet

- java.lang.Object
- - javax.swing.text.TabSet

- All Implemented Interfaces:
    Serializable

      public class TabSet
      extends Object
      implements Serializable

  A TabSet is comprised of many TabStops. It offers methods for locating the closest TabStop to a given position and finding all the potential TabStops. It is also immutable.

  Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the `java.beans` package. Please see `XMLEncoder`.

- - ### Constructor Detail

    - #### TabSet

          public TabSet(TabStop[] tabs)

      Creates and returns an instance of TabSet. The array of Tabs passed in must be sorted in ascending order.

  - ### Method Detail

    - #### getTabCount

          public int getTabCount()

      Returns the number of Tab instances the receiver contains.

    - #### getTab

          public TabStop getTab(int index)

      Returns the TabStop at index `index`. This will throw an IllegalArgumentException if `index` is outside the range of tabs.

    - #### getTabAfter

          public TabStop getTabAfter(float location)

      Returns the Tab instance after `location`. This will return null if there are no tabs after `location`.

    - #### getTabIndex

          public int getTabIndex(TabStop tab)

      Returns:
        the index of the TabStop `tab`, or -1 if `tab` is not contained in the receiver.

    - #### getTabIndexAfter

          public int getTabIndexAfter(float location)

      Returns the index of the Tab to be used after `location`. This will return -1 if there are no tabs after `location`.

    - #### equals

          public boolean equals(Object o)

      Indicates whether this `TabSet` is equal to another one.
      Overrides:
        `equals` in class `Object`
      Parameters:
        `o` - the `TabSet` instance which this instance should be compared to.
      Returns:
        `true` if `o` is the instance of `TabSet`, has the same number of `TabStop`s and they are all equal, `false` otherwise.
      Since:
        1.5
      See Also:
        `Object.hashCode()`, `HashMap`

    - #### hashCode

          public int hashCode()

      Returns a hashcode for this set of TabStops.
      Overrides:
        `hashCode` in class `Object`
      Returns:
        a hashcode value for this set of TabStops.
      Since:
        1.5
      See Also:
        `Object.equals(java.lang.Object)`, `System.identityHashCode(java.lang.Object)`

    - #### toString

          public String toString()

      Returns the string representation of the set of tabs.
      Overrides:
        `toString` in class `Object`
      Returns:
        a string representation of the object.
