Method Detail

analyze

public ClassNameAndSuperclassInfo analyze(IAnalysisCache analysisCache,
                                          ClassDescriptor descriptor)
                                   throws CheckedAnalysisException

Description copied from interface: IAnalysisEngine

Perform an analysis on class or method named by given descriptor.

Specified by:

analyze in interface IAnalysisEngine<ClassDescriptor,ResultType>

Parameters:

analysisCache - the analysis cache

descriptor - the descriptor of the class or method to be analyzed

Returns:

the result of the analysis of the class or method

Throws:

CheckedAnalysisException

registerWith

public void registerWith(IAnalysisCache analysisCache)

Description copied from interface: IAnalysisEngine

Register the analysis engine with given analysis cache.

Specified by:

registerWith in interface IAnalysisEngine<ClassDescriptor,ResultType>

Parameters:

analysisCache - the analysis cache

canRecompute

public boolean canRecompute()

Description copied from interface: IClassAnalysisEngine

Return true if analysis results produced by this analysis engine can be recomputed. Unless some correctness criterion prevents analysis results from being recomputed, analysis engines should return true (allowing the cache to be kept to a manageable size).

Specified by:

canRecompute in interface IClassAnalysisEngine<ClassNameAndSuperclassInfo>

Returns:

true if analysis results produced by this engine can be recomputed, false if for some reason the analysis results must be retained indefinitely
