void	accept(JVMInstructionVisitor insVisitor)
Instruction	execute(ThreadInfo ti) this is the real workhorse returns next instruction to enter in this thread <2do> it's unfortunate we roll every side effect into this method, because it diminishes the value of the 'executeInstruction' notification: all insns that require some sort of late binding (InvokeVirtual, GetField, ..) are not yet fully analyzable (e.g.

Constructor Detail

INVOKESTATIC

protected INVOKESTATIC(java.lang.String clsDescriptor,
                       java.lang.String methodName,
                       java.lang.String signature)

Method Detail

getClassInfo

protected ClassInfo getClassInfo()

getByteCode

public int getByteCode()

toPostExecString

public java.lang.String toPostExecString()

Description copied from class: Instruction

this can contain additional info that was gathered/cached during execution

Specified by:

toPostExecString in interface InstructionInterface

Overrides:

toPostExecString in class Instruction

getStaticElementInfo

public StaticElementInfo getStaticElementInfo()

getClassObjectRef

public int getClassObjectRef()

execute

public Instruction execute(ThreadInfo ti)

Description copied from class: Instruction

this is the real workhorse returns next instruction to enter in this thread <2do> it's unfortunate we roll every side effect into this method, because it diminishes the value of the 'executeInstruction' notification: all insns that require some sort of late binding (InvokeVirtual, GetField, ..) are not yet fully analyzable (e.g. the callee of InvokeVirtuals is not known yet), putting the burden of duplicating the related code of enter() in the listener. It would be better if we factor this 'prepareExecution' out of enter()

Specified by:

execute in interface InstructionInterface

Specified by:

execute in class Instruction

getInvokedMethod

public MethodInfo getInvokedMethod()

Overrides:

getInvokedMethod in class JVMInvokeInstruction

getInvokedMethod

public MethodInfo getInvokedMethod(ThreadInfo ti)

Specified by:

getInvokedMethod in class JVMInvokeInstruction

getInvokedClassInfo

public ClassInfo getInvokedClassInfo()

getInvokedClassName

public java.lang.String getInvokedClassName()

getArgSize

public int getArgSize()

Description copied from class: JVMInvokeInstruction

this is slot size, i.e. includes 'this' for InstanceInvocations

Specified by:

getArgSize in class JVMInvokeInstruction

toString

public java.lang.String toString()

Overrides:

toString in class Instruction

getFieldValue

public java.lang.Object getFieldValue(java.lang.String id,
                                      ThreadInfo ti)

Specified by:

getFieldValue in class JVMInvokeInstruction

accept

public void accept(JVMInstructionVisitor insVisitor)

Specified by:

accept in interface JVMInstruction

Overrides:

accept in class JVMInvokeInstruction

typeSafeClone

public Instruction typeSafeClone(MethodInfo mi)

Description copied from class: Instruction

this is overridden by any Instruction that use a cache for class or method to provide a type safe cloning

Overrides:

typeSafeClone in class JVMInvokeInstruction
