        public boolean matches​(java.lang.String eventType,
                               java.lang.String componentId,
                               int parameterCount)
        Description copied from interface: ComponentEvent
        Returns true if the event matches the provided criteria and the event has not yet been aborted.
        Specified by:
        matches in interface ComponentEvent
        eventType - the type of event (case insensitive match)
        componentId - component is to match against (case insensitive), or the empty string
        parameterCount - minimum number of context values

      • coerceContext

        public java.lang.Object coerceContext​(int index,
                                              java.lang.String desiredTypeName)
        Description copied from interface: ComponentEvent
        Coerces a context value to a particular type. The context is an array of objects; typically it is an array of strings of extra path information encoded into the action URL.
        Specified by:
        coerceContext in interface ComponentEvent
        index - the index of the context value
        desiredTypeName - the desired type
        the coerced value (a wrapper type if the desired type is a primitive)
