类 MaxStackSizeComputer

java.lang.Object

proguard.classfile.attribute.visitor.MaxStackSizeComputer

所有已实现的接口:

AttributeVisitor, ExceptionInfoVisitor, InstructionVisitor

public class MaxStackSizeComputer
extends java.lang.Object
implements AttributeVisitor, InstructionVisitor, ExceptionInfoVisitor

This AttributeVisitor computes the maximum stack size of the code attributes that it visits.

This is a more memory efficient version of StackSizeComputer that doesn't store the stack sizes for every offset.
