Description copied from interface: ObjectGenerator

Prepares the instance for use (reuse) according to the argument passed. Since we can't absolutely be sure that the object being worked on is in valid state or even that it was generated by this instance, we have a chance to refuse to prepare it by returning false.

Specified by:

prepareObject in interface ObjectGenerator

Returns:

true if the preparation succeeded
false if there is something wrong with the object passed

Throws:

java.lang.IllegalArgumentException - if the argument passed for preparation is inappropriate
