Interface AccessibleExtendedText

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.

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.

getTextSequenceAfter

AccessibleTextSequence getTextSequenceAfter(int part,
                                            int index)

Returns the AccessibleTextSequence after a given index.

Parameters:

part - the CHARACTER, WORD, SENTENCE, LINE or ATTRIBUTE_RUN to retrieve

index - an index within the text
