Methods

Modifier and Type	Method and Description
void	addReturnAttr(ThreadInfo ti, Object attr)
protected void	getAndSaveReturnValue(StackFrame frame)
<T> T	getNextReturnAttr(ThreadInfo ti, Class<T> type, Object prev)
Object	getReturnAttr(ThreadInfo ti) this returns all of them - use either if you know there will be only one attribute at a time, or check/process result with ObjectList obviously, this only makes sense from an instructionExecuted(), since the value is pushed during the enter().
<T> T	getReturnAttr(ThreadInfo ti, Class<T> type) this only returns the first attr of this type, there can be more if you don't use client private types or the provided type is too general
protected Object	getReturnedOperandAttr(StackFrame frame)
int	getReturnTypeSize()
boolean	hasReturnAttr(ThreadInfo ti)
boolean	hasReturnAttr(ThreadInfo ti, Class<?> type)
protected void	pushReturnValue(StackFrame frame)
Iterator	returnAttrIterator(ThreadInfo ti)
<T> Iterator<T>	returnAttrIterator(ThreadInfo ti, Class<T> type)
void	setReturnAttr(ThreadInfo ti, Object a) this replaces all of them - use only if you know - there will be only one attribute at a time - you obtained the value you set by a previous getXAttr() - you constructed a multi value list with ObjectList.createList() we don't clone since pushing a return value already changed the caller frame

Specified by:

getReturnedOperandAttr in class ReturnInstruction

getAndSaveReturnValue

protected void getAndSaveReturnValue(StackFrame frame)

Specified by:

hasReturnAttr

public boolean hasReturnAttr(ThreadInfo ti)

Overrides:

hasReturnAttr in class ReturnInstruction

hasReturnAttr

public boolean hasReturnAttr(ThreadInfo ti,
                    Class<?> type)

Overrides:

hasReturnAttr in class ReturnInstruction

getReturnAttr

public Object getReturnAttr(ThreadInfo ti)

this returns all of them - use either if you know there will be only one attribute at a time, or check/process result with ObjectList obviously, this only makes sense from an instructionExecuted(), since the value is pushed during the enter(). Use ObjectList to access values

Overrides:

getReturnAttr in class ReturnInstruction

setReturnAttr

public void setReturnAttr(ThreadInfo ti,
                 Object a)

this replaces all of them - use only if you know - there will be only one attribute at a time - you obtained the value you set by a previous getXAttr() - you constructed a multi value list with ObjectList.createList() we don't clone since pushing a return value already changed the caller frame

Overrides:

setReturnAttr in class ReturnInstruction

getReturnAttr

public <T> T getReturnAttr(ThreadInfo ti,
                  Class<T> type)

this only returns the first attr of this type, there can be more if you don't use client private types or the provided type is too general

Overrides:

getReturnAttr in class ReturnInstruction

getNextReturnAttr

public <T> T getNextReturnAttr(ThreadInfo ti,
                      Class<T> type,
                      Object prev)

Overrides:

getNextReturnAttr in class ReturnInstruction

returnAttrIterator

public Iterator returnAttrIterator(ThreadInfo ti)

Overrides:

returnAttrIterator in class ReturnInstruction

returnAttrIterator

public <T> Iterator<T> returnAttrIterator(ThreadInfo ti,
                                 Class<T> type)

Overrides:

returnAttrIterator in class ReturnInstruction

addReturnAttr

public void addReturnAttr(ThreadInfo ti,
                 Object attr)

Overrides:

addReturnAttr in class ReturnInstruction
