oracle.javatools.parser.java.v1
Class JavaTreeGenerator

java.lang.Object
  oracle.javatools.parser.java.v1.JavaTreeGenerator

All Implemented Interfaces:

JavaSyntaxCodes, SyntaxListener

public class JavaTreeGenerator
extends java.lang.Object
implements JavaSyntaxCodes, SyntaxListener

The TreeGenerator is the glue between the SyntaxRecognizer and the SymbolFactory. When a syntax token indicates a new element, we create a new parse tree node. When a syntax token indicates the close of an element, we finish off the corresponding parse tree node. For details and specifics of the underlying parse data structure, see the JavaSymbolFactory.

The idea is to generate the entire tree by maintaining a single stack. Start by pushing a root node onto the stack and generate the rest of the tree in an in-order depth-first fashion.
