构造器详细资料

ReferenceTracingValueFactory

public ReferenceTracingValueFactory(ValueFactory valueFactory)

Creates a new ReferenceTracingValueFactory that attaches instruction offset values based on being used as an instruction visitor. This instance preserves trace values in the cast(proguard.evaluation.value.TracedReferenceValue, java.lang.String, proguard.classfile.Clazz, boolean) method.

参数:

valueFactory - the value factory that creates the actual values.

ReferenceTracingValueFactory

public ReferenceTracingValueFactory(ValueFactory valueFactory,
