Method Details

readSccData

protected static void readSccData(Class<?> generatedRootClass,
 String filename,
 Map<Integer,Map<Class<?>,Integer>> class2scc,
 Map<Integer,Multimap<String,Integer>> field2sccs,
 Map<Integer,Multimap<Class<?>,Integer>> class2reachedSccs)

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,Map<Class<?>,Integer>> get_class2scc()

Overwritten at one single place, namely in basematcher.

get_field2sccs

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

Overwritten at one single place, namely in basematcher.

get_class2reachedSccs

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

Overwritten at one single place, namely in basematcher.

compile

public OptimizingVisitor compile()

The user-derived visitor must not be declared final and CURRENTLY must have one parameter-les constructor, which is used by the code compile here. This also forbids inner claases reading context parameters.

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_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 (not including) "upto".

calculateFlags

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