public static interface AbstractDocument.Content
Interface to describe a sequence of character content that can be edited. Implementations may or may not support a history mechanism which will be reflected by whether or not mutations return an UndoableEdit implementation.
AbstractDocument| Method Summary | |
|---|---|
Position |
createPosition(int offset)
Creates a position within the content that will track change as the content is mutated. |
void |
getChars(int where,
int len,
Segment txt)
Gets a sequence of characters and copies them into a Segment. |
String |
getString(int where,
int len)
Fetches a string of characters contained in the sequence. |
UndoableEdit |
insertString(int where,
String str)
Inserts a string of characters into the sequence. |
int |
length()
Current length of the sequence of character content. |
UndoableEdit |
remove(int where,
int nitems)
Removes some portion of the sequence. |
| Method Detail |

Position createPosition(int offset)
throws BadLocationException
offset - the offset in the content >= 0
BadLocationException - for an invalid offsetint length()
UndoableEdit insertString(int where,
String str)
throws BadLocationException
where - offset into the sequence to make the insertion >= 0str - string to insert
Edit implementation will be returned,
otherwise returns null
BadLocationException - thrown if the area covered by
the arguments is not contained in the character sequence
UndoableEdit remove(int where,
int nitems)
throws BadLocationException
where - The offset into the sequence to make the
insertion >= 0.nitems - The number of items in the sequence to remove >= 0.
BadLocationException - Thrown if the area covered by
the arguments is not contained in the character sequence.
String getString(int where,
int len)
throws BadLocationException
where - Offset into the sequence to fetch >= 0.len - number of characters to copy >= 0.
BadLocationException - Thrown if the area covered by
the arguments is not contained in the character sequence.
void getChars(int where,
int len,
Segment txt)
throws BadLocationException
where - the starting offset >= 0len - the number of characters >= 0txt - the target location to copy into
BadLocationException - Thrown if the area covered by
the arguments is not contained in the character sequence.
