meta.event - meta.event class describes MATLAB class events

Description

The meta.event class provides information about MATLAB class events. The read/write properties of the meta.event class correspond to event attributes and are specified only from within class definitions.

You can query the read-only properties of the meta.event object to obtain information that is specified syntactically by the class (for example, to obtain the name of the class defining the event).

You cannot instantiate a meta.event object directly. Obtain a meta.event object from the meta.class Events property, which contains a cell array of meta.event objects, one for each event defined by the class. For example:

mco = ?classname;
eventcell = mco.Events;
eventcell{1}.Name; % name of first event

Use the metaclass function to obtain a meta.class object from a class instance:

mco = metaclass(obj);

Properties

Property	Purpose
Name read only	Name of the event.
Description read only	Currently not used
DetailedDescription read only	Currently not used
Hidden	If true, the event does not appear in the list of events returned by the events function (or other event listing functions or viewers)
ListenAccess	Determines where you can create listeners for the event. public — unrestricted access protected — access from methods in class or derived classes private — access by class methods only (not from derived classes)
NotifyAccess	Determines where code can trigger the event. public — any code can trigger event protected — can trigger event from methods in class or derived classes private — can trigger event by class methods only (not from derived classes)
DefiningClass	The meta.class object representing the class that defines this event.
