All Implemented Interfaces:

Parser

public class JavaParser
extends AbstractParser

Parses Java code in an RSyntaxTextArea.

Like all RSTA Parsers, a JavaParser instance is notified when the RSTA's text content changes. After a small delay, it will parse the content as Java code, building an AST and looking for any errors. When parsing is complete, a property change event of type PROPERTY_COMPILATION_UNIT is fired. Listeners can check the new value of the property for the CompilationUnit built that represents the source code in the text area. Note that the CompilationUnit may be incomplete if there were parsing/syntax errors (it will usually be complete "up to" the error in the content).

This parser cannot be shared amongst multiple instances of RSyntaxTextArea.

Please keep in mind that this class is a work-in-progress!
