quietlyInvokeMethodsWithAnnotation

public static boolean quietlyInvokeMethodsWithAnnotation(Class<? extends Annotation> annotation,
                                                         Object instance,
                                                         ComponentLog logger,
                                                         Object... args)

Invokes all methods on the given instance that have been annotated with the given annotation. If the signature of the method that is defined in instance uses 1 or more parameters, those parameters must be specified by the args parameter. However, if more arguments are supplied by the args parameter than needed, the extra arguments will be ignored.

Parameters:

annotation - annotation

instance - instance

logger - the ComponentLog to use for logging any errors. If null, will use own logger, but that will not generate bulletins or easily tie to the Processor's log messages.

args - args

Returns:

true if all appropriate methods were invoked and returned without throwing an Exception, false if one of the methods threw an Exception or could not be invoked; if false is returned, an error will have been logged.
