)

ExceptionCondition
NotSupportedException

component is a cross-process remoted object.

The events for the component parameter can differ from the events of a class, because the site can add or remove events if the component parameter is sited.

The attributes array can have a mix of Type and Attribute objects. Filtering is defined by the following rules:

  • A Type is treated as a wildcard; it matches any event that has the Type in its set of attributes.

  • If an event does not have an Attribute of the same class, the event is not included in the returned array.

  • If the attribute is an instance of the Attribute class, the event must be an exact match or it is not included in the returned array.

  • If an Attribute instance is specified and it is the default event, it is included in the returned array even if there is no instance of the Attribute in the event.

If component is null, an empty collection is returned.

The order of the returned collection is not guaranteed to be identical between calls, so always order it before use.
