类 SideEffectInstructionChecker

  • 所有已实现的接口:
    proguard.classfile.constant.visitor.ConstantVisitor, proguard.classfile.instruction.visitor.InstructionVisitor, proguard.classfile.visitor.MemberVisitor
    public class SideEffectInstructionChecker
extends java.lang.Object
implements proguard.classfile.instruction.visitor.InstructionVisitor, proguard.classfile.constant.visitor.ConstantVisitor, proguard.classfile.visitor.MemberVisitor
    This class can tell whether an instruction has any side effects. This includes invoking methods that have side effects, writing to fields that are not write-only, and throwing exceptions. Return instructions and array store instructions can be included or not. With the environment setting "optimize.conservatively", it also accounts for all possible NullPointerExceptions, ArrayIndexOutOfBoundExceptions, etc., which are typically accidental, not intentional.
