      • VariableOptimizer

        public VariableOptimizer​(boolean reuseThis)
        Creates a new VariableOptimizer.
        参数:
        reuseThis - specifies whether the 'this' variable can be reused. Many JVMs for JME and IBM's JVMs for JSE can't handle such reuse.

      • VariableOptimizer

        public VariableOptimizer​(boolean reuseThis,
                         proguard.classfile.visitor.MemberVisitor extraVariableMemberVisitor)
        Creates a new VariableOptimizer with an extra visitor.
        参数:
        reuseThis - specifies whether the 'this' variable can be reused. Many JVMs for JME and IBM's JVMs for JSE can't handle such reuse.
        extraVariableMemberVisitor - an optional extra visitor for all removed variables.
