Class NotificationFilterSupport

Implemented Interfaces:
NotificationFilter, Serializable

public class NotificationFilterSupport
extends Object
implements NotificationFilter

Performs filtering of Notifications based on a list of type prefixes. The type of a notification is compared with each member of the list using String.startsWith(String) and, if one matches, the notification is allowed to pass through the filter. Matching on the beginning of the string is used in preference to wildcards, so type.* will match only notifications with a type beginning with code>type.*, not type. as expected.
Since:
1.5
