Class IteratorInsertion

java.lang.Object
  tudresden.ocl.normalize.IteratorInsertion

All Implemented Interfaces:

NodeNormalizer

public class IteratorInsertion

extends Object

implements NodeNormalizer

This node normalizer inserts an iterator in every iterating method that does not already have one (or more). This is a prerequisite to the normalization step "DefaultContextInsertion" but breaks to results of "TypeInformationInsertion".

Method Summary

void	close(OclTree tree, NormalizerPass pass) This method notifies the NodeNormalizer of the end of a tree normalization.
void	normalize(Node n, OclTree tree) normalize a single node
void	open(OclTree tree, NormalizerPass pass) allows the NodeNormalizers to initialize itself.

Method Detail

open

public void open(OclTree tree,
                 NormalizerPass pass)

Description copied from interface: NodeNormalizer

allows the NodeNormalizers to initialize itself. In this method, a NodeNormalizer typically makes sure that the AST fulfills the preconditions it requires and then registers its own postconditions.

Specified by:

open in interface NodeNormalizer

close

public void close(OclTree tree,
                  NormalizerPass pass)

Description copied from interface: NodeNormalizer

This method notifies the NodeNormalizer of the end of a tree normalization. Here new invariants on the tree can be registered that were not registered in open() already

Specified by:

close in interface NodeNormalizer

normalize

public void normalize(Node n,
                      OclTree tree)

Description copied from interface: NodeNormalizer

normalize a single node
