tryExecute
Tries to reuse this executor, checking that it is compatible with the actual set of arguments.Compatibility means that:
o
must be of the same class as this executor's target class,property
must be of the same class as this executor's target property (for list and map based executors) and have the same value (for other types) and thatarg
must be a valid argument for this executor underlying method.- Overrides:
tryExecute
in classAbstractExecutor.Set
- Parameters:
o
- The object to invoke the method from.identifier
