Class CompilationUnit

java.lang.Object

org.walkmod.javalang.ast.Node

org.walkmod.javalang.ast.CompilationUnit

All Implemented Interfaces:

Serializable, Cloneable, org.walkmod.merger.IdentificableNode, org.walkmod.merger.Mergeable<CompilationUnit>, org.walkmod.modelchecker.ConstrainedElement

public final class CompilationUnit
extends Node
implements org.walkmod.merger.Mergeable<CompilationUnit>

This class represents the entire compilation unit. Each java file denotes a compilation unit.

The CompilationUnit is constructed following the syntax:

CompilationUnit
