protected void insertUpdate(DefaultDocumentEvent chng,
                            AttributeSet attr)

Updates document structure as a result of text insertion. This will happen within a write lock. Since this document simply maps out lines, we refresh the line map.

Parameters:

chng - the change event

attr - the set of attributes

Overrides:

insertUpdate in class AbstractDocument

protected void removeUpdate(DefaultDocumentEvent chng)

Updates any document structure as a result of text removal. This will happen within a write lock. Since the structure represents a line map, this just checks to see if the removal spans lines. If it does, the two lines outside of the removal area are joined together.

Parameters:

chng - the change event

Overrides:

removeUpdate in class AbstractDocument
