Change "Method's Return Value"

Method Name	Usage
addReturnValue	If "doSomething" method has a return value addReturnValue("jp.co.dgic.Sample", "doSomething", new Integer(1)); If "doSomething" method has NO return value(Return value Type is "void") addReturnValue("jp.co.dgic.Sample", "doSomething");
setReturnValueAt	If "doSomething" method has a return value addReturnValueAt("jp.co.dgic.Sample", "doSomething", 3, new Integer(1)); If "doSomething" method has NO return value(Return value Type is "void") addReturnValueAt("jp.co.dgic.Sample", "doSomething", 3);
setReturnValueAtAllTimes	If "doSomething" method has a return value addReturnValueAtAllTimes("jp.co.dgic.Sample", "doSomething", new Integer(1)); If "doSomething" method has NO return value(Return value Type is "void") addReturnValueAtAllTimes("jp.co.dgic.Sample", "doSomething");
addReturnNull	Same as addReturnValue
setReturnNullAt	Same as addReturnValueAt
setReturnNullAtAllTimes	Same as addReturnValueAtAllTimes
