Constructor Detail

FixedNameEventFilter

public FixedNameEventFilter(String filter)

Constructor initializing this event filter with a document name that should be matched.

Method Detail

getFilter

public String getFilter()

Description copied from interface: EventFilter

Provides access to the filter's criterion.

Specified by:

getFilter in interface EventFilter

Returns:

the filter used in the EventFilter.matches(EventFilter) method to verify if a passed event filter matches it.

EventFilter.matches(EventFilter)

matches

public boolean matches(EventFilter eventFilter)

Description copied from interface: EventFilter

Compares two event filters to see if they match, meaning that the "contexts" of two events are compatible. For example, a FixedNameEventFilter matches another filter only if they both have the same name set as the filter, while an AlwaysMatchingEventFilter matches any other event filter. A listener that registered to receive notifications like referenceEvent and with referenceEventFilter, will be notified of any occuring event for which referenceEvent.matches(occuringEvent) will return true and referenceEvent.getEventFilter().matches(occurringEvent.getEventFilter()).

Specified by:

matches in interface EventFilter

Parameters:

eventFilter - the event filter to compare to the filter value

Returns:

true if both event filters match. The matching algorithm is left to the filter event implementation. For example the Regex event filter will match another filter if that other filter matches the regex.
