Constructor Details

ClassReferenceFixer

public ClassReferenceFixer(boolean ensureUniqueMemberNames)

Creates a new ClassReferenceFixer.

Parameters:

ClassReferenceFixer

public ClassReferenceFixer(ClassReferenceFixer.NameGenerationStrategy newNameStrategy)

Creates a new ClassReferenceFixer.

Parameters:

newNameStrategy - specifies how class members whose descriptor changes should get a new name in order to avoid naming conflicts with similar members.
