Method Detail

getTokenMarker

public TokenMarker getTokenMarker()

Returns the token marker that is to be used to split lines of this document up into tokens. May return null if this document is not to be colorized.

setTokenMarker

public void setTokenMarker(TokenMarker tm)

Sets the token marker that is to be used to split lines of this document up into tokens. May throw an exception if this is not supported for this type of document.

Parameters:

tm - The new token marker

tokenizeLines

public void tokenizeLines()

Reparses the document, by passing all lines to the token marker. This should be called after the document is first loaded.

tokenizeLines

public void tokenizeLines(int start,
                 int len)

Reparses the document, by passing the specified lines to the token marker. This should be called after a large quantity of text is first inserted.

Parameters:

start - The first line to parse

len - The number of lines, after the first one to parse

beginStructEdit

public void beginStructEdit()

Starts a compound edit that can be undone in one operation. Subclasses that implement undo should override this method; this class has no undo functionality so this method is empty.

endStructEdit

public void endStructEdit()

Ends a compound edit that can be undone in one operation. Subclasses that implement undo should override this method; this class has no undo functionality so this method is empty.

addUndoableEdit

public void addUndoableEdit(UndoableEdit edit)

Adds an undoable edit to this document's undo list. The edit should be ignored if something is currently being undone.

Parameters:

edit - The undoable edit

Since:

jEdit 2.2pre1

fireInsertUpdate

protected void fireInsertUpdate(DocumentEvent evt)

We overwrite this method to update the token marker state immediately so that any event listeners get a consistent token marker.

Overrides:

fireInsertUpdate in class AbstractDocument

fireRemoveUpdate

protected void fireRemoveUpdate(DocumentEvent evt)

We overwrite this method to update the token marker state immediately so that any event listeners get a consistent token marker.

Overrides:

fireRemoveUpdate in class AbstractDocument
