public class ParseTree
extends Object

An abstract syntax tree for JavaScript parse trees. Immutable. A plain old data structure. Should include data members and simple accessors only. Derived classes should have a 'Tree' suffix. Each concrete derived class should have a ParseTreeType whose name matches the derived class name. A parse tree derived from source should have a non-null location. A parse tree that is synthesized by the compiler may have a null location. When adding a new subclass of ParseTree you must also do the following: - add a new entry to ParseTreeType - add ParseTree.asXTree()

public boolean isStatementStandard()

This function reflects the ECMA standard, or what we would expect to become the ECMA standard. Most places use isStatement instead which reflects where code on the web diverges from the standard.

isSourceElement

public boolean isSourceElement()
