Constructor Detail

ClassMerger

public ClassMerger(ProgramClass targetClass,
                   boolean allowAccessModification,
                   boolean mergeInterfacesAggressively)

Creates a new ClassMerger that will merge classes into the given target class.

Parameters:

targetClass - the class into which all visited classes will be merged.

allowAccessModification - specifies whether the access modifiers of classes can be changed in order to merge them.

mergeInterfacesAggressively - specifies whether interfaces may be merged aggressively.
