# Interface AccessibleExtendedText

All Known Implementing Classes:

public interface AccessibleExtendedText
The `AccessibleExtendedText` interface contains additional methods not provided by the `AccessibleText` interface.

Applications can determine if an object supports the `AccessibleExtendedText` interface by first obtaining its `AccessibleContext` (see `Accessible`) and then calling the `AccessibleContext.getAccessibleText()` method of `AccessibleContext`. If the return value is an instance of `AccessibleExtendedText`, the object supports this interface.

  - ### getTextRange

    String getTextRange(int startIndex, int endIndex)
    Returns the text between two indices.
    Parameters:
      `startIndex` - the start index in the text
      `endIndex` - the end index in the text
    Returns:
      the text string if the indices are valid. Otherwise, `null` is returned.

  - ### getTextSequenceAt

    AccessibleTextSequence getTextSequenceAt(int part, int index)
    Returns the `AccessibleTextSequence` at a given index.

      `index` - an index within the text
    Returns:
      an `AccessibleTextSequence` specifying the text if `part` and `index` are valid. Otherwise, `null` is returned.

    Parameters:
      `part` - the `CHARACTER`, `WORD`, `SENTENCE`, `LINE` or `ATTRIBUTE_RUN` to retrieve
      `index` - an index within the text
    Returns:
      an `AccessibleTextSequence` specifying the text if `part` and `index` are valid. Otherwise, `null` is returned.

      - `AccessibleText.CHARACTER`
      - `AccessibleText.WORD`
      - `AccessibleText.SENTENCE`

  - ### getTextSequenceBefore

    AccessibleTextSequence getTextSequenceBefore(int part, int index)
    Returns the `AccessibleTextSequence` before a given index.
    Parameters:
      `part` - the `CHARACTER`, `WORD`, `SENTENCE`, `LINE` or `ATTRIBUTE_RUN` to retrieve
      `index` - an index within the text
    Returns:
      an `AccessibleTextSequence` specifying the text if `part` and `index` are valid. Otherwise, `null` is returned.

    Returns the bounding rectangle of the text between two indices.
    Parameters:
      `startIndex` - the start index in the text
      `endIndex` - the end index in the text
    Returns:
      the bounding rectangle of the text if the indices are valid. Otherwise, `null` is returned.
