Class CodeGenAnalyzer

java.lang.Object
  org.eclipse.ocl.examples.codegen.analyzer.CodeGenAnalyzer

public class CodeGenAnalyzer
extends java.lang.Object

A CodeGenAnalyzer performs the analysis of a Pivot AST in preparation for code generation.

Pass 1: Pivot2CGAnalysisVisitor
Each Pivot Element is converted to a CGElement
This conversion creates objects such as CGLibraryOperationCallEXp that are more atuned to CG and provides a tree that can be rewritten by optimizations.

Pass 2: CGPreAnalysisVisitor
Traversal of the CG containment tree performs
constant folding

Pass N-1: CG2JavaPreVisitor
Traversal of the CG containment tree prepares for Java CG by
gathering imports

Pass N: CG2JavaVisitor
Traversal of the CG containment tree emits code
