All Implemented Interfaces:

java.io.Serializable, javax.swing.text.Document

public class JavaDocument
extends UndoableDocument

A document to represent text in the form of the java programming language. This is quite primitive in that it simply provides support for lexically analyzing the text.

Method Detail

createScanner

public JavaDocument.Scanner createScanner()

Create a lexical analyzer for this document.

getScannerStart

public int getScannerStart(int p)

Fetch a reasonable location to start scanning given the desired start location. This allows for adjustments needed to accomodate multiline comments.

insertUpdate

protected void insertUpdate(javax.swing.text.AbstractDocument.DefaultDocumentEvent chng,
                            javax.swing.text.AttributeSet attr)

Updates document structure as a result of text insertion. This will happen within a write lock. The superclass behavior of updating the line map is executed followed by marking any comment areas that should backtracked before scanning.

Overrides:

insertUpdate in class javax.swing.text.PlainDocument

Parameters:

chng - the change event

attr - the set of attributes

removeUpdate

protected void removeUpdate(javax.swing.text.AbstractDocument.DefaultDocumentEvent chng)

Updates any document structure as a result of text removal. This will happen within a write lock. The superclass behavior of updating the line map is executed followed by placing a lexical update command on the analyzer queue.

Overrides:

removeUpdate in class javax.swing.text.PlainDocument

Parameters:

chng - the change event
