Interface EventFilter

All Known Implementing Classes:
AbstractEventFilter, AspectAddedFilter, AspectRemovedFilter, AssocTypeFilter, ContentAddedFilter, ContentChangedFilter, EventTypeFilter, IsFileFilter, IsFolderFilter, MimeTypeFilter, NodeAspectFilter, NodeMovedFilter, NodeTypeChangedFilter, NodeTypeFilter, PropertyAddedFilter, PropertyChangedFilter, PropertyCurrentValueFilter, PropertyPreviousValueFilter, PropertyRemovedFilter, PropertyValueFilter
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface EventFilter
Predicate definition for the class RepoEvent to be able to define event filters that check different conditions in the corresponding events (i.e. the node type has changed, a property has a specific value, etc.).

These event filters can be used in the event handlers (EventHandler) to narrow down the conditions required to execute the custom behaviour the integrator is aiming when implementing an event handler.

  • Method Summary

    Modifier and Type
    Method
    Description
    default EventFilter
    and(EventFilter other)
    Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
    default EventFilter
    negate()
    Returns a predicate that represents the logical negation of this predicate.
    default EventFilter
    or(EventFilter other)
    Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
    boolean
    test(org.alfresco.repo.event.v1.model.RepoEvent<org.alfresco.repo.event.v1.model.DataAttributes<org.alfresco.repo.event.v1.model.Resource>> event)
    Evaluates this predicate on the given argument.

  • Method Details

    • test

      boolean test(org.alfresco.repo.event.v1.model.RepoEvent<org.alfresco.repo.event.v1.model.DataAttributes<org.alfresco.repo.event.v1.model.Resource>> event)
      Evaluates this predicate on the given argument.
      Parameters:
      event - the input argument
      Returns:
      true if the input argument matches the predicate, otherwise false

    • and

      default EventFilter and(EventFilter other)
      Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. When evaluating the composed predicate, if this predicate is false, then the other predicate is not evaluated.

      Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

      Parameters:
      other - a predicate that will be logically-ANDed with this predicate
      Returns:
      a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate
      Throws:
      NullPointerException - if other is null

    • negate

      default EventFilter negate()
      Returns a predicate that represents the logical negation of this predicate.
      Returns:
      a predicate that represents the logical negation of this predicate

    • or

      default EventFilter or(EventFilter other)
      Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. When evaluating the composed predicate, if this predicate is true, then the other predicate is not evaluated.

      Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

      Parameters:
      other - a predicate that will be logically-ORed with this predicate
      Returns:
      a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate
      Throws:
      NullPointerException - if other is null
