Class LazyObjectRecorder

java.lang.Object
  java.lang.Thread
      patterntesting.runtime.log.AbstractLogger
          patterntesting.runtime.log.ObjectRecorder
              patterntesting.runtime.log.LazyObjectRecorder

All Implemented Interfaces:

Runnable

public class LazyObjectRecorder
extends ObjectRecorder

In contradiction to ObjectRecorder this class only records joinpoints and return values if they are different from the last record. I.e. If a return value is always the same for the same joinpoint this pair is only recorded once.

1.3.1 (01.09.2013)

Method Detail

log

@NullArgsAllowed
public void log(JoinPoint joinPoint,
                                Object returnValue)

Both things are logged with this method: the call of a method (joinPoint) and the return value of this method. Constructors or method of type 'void' are not recorded because the have no return value.

Because the given joinPoint cannot be used as key for a map in

Overrides:

log in class ObjectRecorder

Parameters:

joinPoint - the joinpoint

returnValue - the return value ObjectPlayer it is saved as string. As a side effect this will speedup the serialization stuff and shorten the generated record file.

The given return value will be only stored if it is not the same as the last time.
