 public interface AccessibleTextTheAccessibleTextinterface should be implemented by all classes that present textual information on the display. This interface provides the standard mechanism for an assistive technology to access that text via its content, attributes, and spatial location. Applications can determine if an object supports theAccessibleTextinterface by first obtaining itsAccessibleContext(seeAccessible) and then calling theAccessibleContext.getAccessibleText()method ofAccessibleContext. If the return value is notnull, the object supports this interface.

Field Detail- 
CHARACTERstatic final int CHARACTER Constant used to indicate that the part of the text that should be retrieved is a character.
 - 
WORDstatic final int WORD Constant used to indicate that the part of the text that should be retrieved is a word.
 - 
SENTENCEstatic final int SENTENCE Constant used to indicate that the part of the text that should be retrieved is a sentence.A sentence is a string of words which expresses an assertion, a question, a command, a wish, an exclamation, or the performance of an action. In English locales, the string usually begins with a capital letter and concludes with appropriate end punctuation; such as a period, question or exclamation mark. Other locales may use different capitalization and/or punctuation.

Method Detail- 
getIndexAtPointint getIndexAtPoint(Point p) Given a point in local coordinates, return the zero-based index of the character under that point. If the point is invalid, this method returns -1.- Parameters:
- p- the point in local coordinates
- Returns:
- the zero-based index of the character under Point p; if point is invalid return -1.
 
 - 
getCharacterBoundsRectangle getCharacterBounds(int i) Determines the bounding box of the character at the given index into the string. The bounds are returned in local coordinates. If the index is invalid an empty rectangle is returned.- Parameters:
- i- the index into the string
- Returns:
- the screen coordinates of the character's bounding box, if index is invalid return an empty rectangle.
 
 - 
getCharCountint getCharCount() Returns the number of characters (valid indicies).- Returns:
- the number of characters
 
 - 
getCaretPositionint getCaretPosition() Returns the zero-based offset of the caret.Note: That to the right of the caret will have the same index value as the offset (the caret is between two characters). - Returns:
- the zero-based offset of the caret
 
 - 
getAtIndexString getAtIndex(int part, int index) Returns theStringat a given index.- Parameters:
- part- the CHARACTER, WORD, or SENTENCE to retrieve
- index- an index within the text
- Returns:
- the letter, word, or sentence
 
 - 
getAfterIndexString getAfterIndex(int part, int index) Returns theStringafter a given index.- Parameters:
- part- the CHARACTER, WORD, or SENTENCE to retrieve
- index- an index within the text
- Returns:
- the letter, word, or sentence
 
 - 
getBeforeIndexString getBeforeIndex(int part, int index) Returns theStringbefore a given index.- Parameters:
- part- the CHARACTER, WORD, or SENTENCE to retrieve
- index- an index within the text
- Returns:
- the letter, word, or sentence
 
 - 
getCharacterAttributeAttributeSet getCharacterAttribute(int i) Returns theAttributeSetfor a given character at a given index.- Parameters:
- i- the zero-based index into the text
- Returns:
- the AttributeSetof the character
 
 - 
getSelectionStartint getSelectionStart() Returns the start offset within the selected text. If there is no selection, but there is a caret, the start and end offsets will be the same.- Returns:
- the index into the text of the start of the selection
 
 - 
getSelectionEndint getSelectionEnd() Returns the end offset within the selected text. If there is no selection, but there is a caret, the start and end offsets will be the same.- Returns:
- the index into the text of the end of the selection
 
 - 
getSelectedTextString getSelectedText() Returns the portion of the text that is selected.- Returns:
- the Stringportion of the text that is selected
