Returns:

the source of the event.

getEvent

public Object getEvent()

Gets the event that originated this trigger object. Typically, this will be target-specific, as different targets have their own event types.

Returns:

the event object, target specific.

toString

public String toString()

Returns the string representation of this EventMethod. The returned string contains the method name, the event object and the event source.

Overrides:

toString in class Object
