OptimizingVisitor

protected OptimizingVisitor()

Method Detail

getLowestGeneratedClass

protected Class getLowestGeneratedClass()

Is overwritten by the umod compiler to the lowest generated class. A "null" value indicates a non-user-defined visitor, e.g. Dumper or XML serializer, which is never subject to optimization.

getKey

protected int getKey()

Overwritten with generated code to return visitor register key number.

allFields2codeNumber

protected String[] allFields2codeNumber()

get_class2scc

protected abstract Map<Integer,? extends Map<Class,Integer>> get_class2scc()

Overwritten at one single place, namely in basematcher.

get_field2sccs

protected abstract Map<Integer,? extends Multimap<String,Integer>> get_field2sccs()

Overwritten at one single place, namely in basematcher.

get_class2reachedSccs

protected abstract Map<Integer,? extends Multimap<Class,Integer>> get_class2reachedSccs()

Overwritten at one single place, namely in basematcher.

collectFlags

protected void collectFlags()

Re-defined in the generated code according to the flavour of visitor. Calls "collectFlags_action()", "collectFlags_actionDorewrite()", etc. depending on what method names have to be collected.
(( Could be "abstract", but this would require a dummy implementation for "Dumper", "XML-(de-)serializer", etc. ))

collectFlags_action

protected void collectFlags_action()

collectFlags_actionRewritefields

protected void collectFlags_actionRewritefields()

collectFlags_actionDorewrite

protected void collectFlags_actionDorewrite()

collectFlags_actionPreDescendPost

protected void collectFlags_actionPreDescendPost()

collectMethods

protected static void collectMethods(Class cls,
                                     Class upto,
                                     Set<Class> classes,
                                     String methodname)

Looks for all methods with name "methodname" in class "cls", and inserts the class of their 0th (and only) argument into classes. Does so recursively with the superclasses up to and including "upto".

calculateFlags

protected void calculateFlags(Class ownclass,
                              Set<Class> overwritten)
