insertUpdate
public final void insertUpdate(javax.swing.event.DocumentEvent change)
- Gives notification that there was an insert into the document. The
range given by the DocumentEvent bounds the freshly inserted region.
- Specified by:
insertUpdate
in interface javax.swing.event.DocumentListener
- Parameters:
e
- the document event
removeUpdate
public final void removeUpdate(javax.swing.event.DocumentEvent change)
- Gives notification that a portion of the document has been
removed. The range is given in terms of what the view last
saw (that is, before updating sticky positions).
- Specified by:
removeUpdate
in interface javax.swing.event.DocumentListener
- Parameters:
e
- the document event
changedUpdate
public final void changedUpdate(javax.swing.event.DocumentEvent e)
- Gives notification that an attribute or set of attributes changed.
- Specified by:
changedUpdate
in interface javax.swing.event.DocumentListener
- Parameters:
e
- the document event
scanLine
public void scanLine(javax.swing.text.Document doc,
int lineIndex,
MultiStateLexer lexer,
MultiStateLexer.LexerCallback action)
updateLine
public boolean updateLine(javax.swing.text.Document doc,
int lineIndex,
MultiStateLexer lexer)
- Updates the state attribute of the current line. If the attribute has
changed, marks the next line as "dirty".
setLexerLine
public void setLexerLine(javax.swing.text.Document doc,
int lineIndex,
MultiStateLexer lexer)
- Restricts the lexer scan range to the specified line. The starting state
is fetched from the line element attribute list.
