                              InvocationParameter[] parameters)

invoke an Action by name

Parameters:

collection - the property collection

actionName - the action name to invoke

parameters - the list of parameter and value to invoke. Any parameter not in this list will be assigned a default value. If a parameter doesn't have a default value, an InvocationTargetException will be thrown.

Returns:

the action return value

Throws:

java.lang.IllegalArgumentException - if some of the parameters are wrong or missing or the action fails to compile.

java.lang.reflect.InvocationTargetException - if the action code throws an exception.

java.lang.NullPointerException - if the collection or actionName parameters are null.

CompilationFailedException - if action failed to compile.

java.lang.IllegalStateException - if action isn't enabled.

invokeActionSilent

java.lang.Object invokeActionSilent(PropertyCollection<?,?> collection,
                                    java.lang.String actionName,
                                    InvocationParameter[] parameters)

invoke an Action by name silently. Meaning that all exceptions detected during the action execution will be logged but not thrown back.

Parameters:

collection - the property collection

actionName - the action name to invoke

parameters - the list of parameter and value to invoke. Any parameter not in this list will be assigned a default value. If a parameter doesn't have a default value, an InvocationTargetException will be thrown.

Returns:

the action return value
