public interface Value extends Mirror
目标VM中值的镜像。 此接口是包含原始值和对象值的值层次结构的根。可以访问值的一些示例：
ObjectReference.getValue(Field)- value of a field StackFrame.getValue(LocalVariable)- value of a variable VirtualMachine.mirrorOf(double)- created in the target VM by the JDI client ModificationWatchpointEvent.valueToBe()- returned with an event 下表说明了Value的哪些子接口用于镜像目标VM中的值 -
