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.

           boolean allowAccessModification,
           boolean mergeInterfacesAggressively,
           ClassVisitor extraClassVisitor)

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.

extraClassVisitor - an optional extra visitor for all merged classes.
