[Java] Class OperandStack

public class OperandStack
extends Object

Constructor Detail

public OperandStack(WriterController wc)

Method Detail

public ClassNode box()

public void castToBool(int mark, boolean emptyDefault)

ensure last marked parameter on the stack is a primitive boolean if mark==stack size, we assume an empty expression or statement. was used and we will use the value given in emptyDefault as boolean if mark==stack.size()-1 the top element will be cast to boolean using Groovy truth. In other cases we throw a GroovyBugError

public void doAsType(ClassNode targetType)

public void doGroovyCast(ClassNode targetType)

do Groovy cast for top level element

public void doGroovyCast(Variable v)

public void dup()

duplicate top element

public int getStackLength()

public ClassNode getTopOperand()

public org.objectweb.asm.Label jump(int ifIns)

public void jump(int ifIns, org.objectweb.asm.Label label)

public void load(ClassNode type, int idx)

public void loadOrStoreVariable(BytecodeVariable variable, boolean useReferenceDirectly)

public void pop()

remove operand stack top element using bytecode pop

public void popDownTo(int elements)

public void push(ClassNode type)

push operand on stack

public void pushBool(boolean inclusive)

public void pushConstant(ConstantExpression expression)

load the constant on the operand stack.

public void pushDynamicName(Expression name)

public void remove(int amount)

Remove amount elements from the operand stack, without using pop. For example after a method invocation

public void replace(ClassNode type)

replace top level element with new element of given type

public void replace(ClassNode type, int n)

replace n top level elements with new element of given type

public void storeVar(BytecodeVariable variable)

public void swap()

swap two top level operands

public String toString()
