How to retry if onExecute() has not good result ?

[bidasknakayama]

Hi, I am testing TaskQueue. It look like very good : )

protected Boolean onExecute() throws Exception {
     if( a_Task() == true ){
           return true;
     }else{
           return false;
     }
}

When False, I want to retry Task. How to write it ? We need more example.
