The EventHandler interface defines the contract for an Alfresco repository event handler implementation.

This contract has been reduced to a minimum:

• The type of event the handler will manage.
• Other conditions, called filters, the event must match before it is handled (defaults to none). See Event filter.
• The code to execute when the event is triggered. The business logic implementation for your domain.

A hierarchy of interfaces that extend EventHandler have been defined to cover the different types of Alfresco repository events that can be triggered by the Content Services event system:

• Node created - OnNodeCreatedEventHandler .
• Node updated - OnNodeUpdatedEventHandler .
• Node deleted - OnNodeDeletedEventHandler .
• Parent-Child Association created - OnChildAssocCreatedEventHandler .
• Parent-Child Association deleted - OnChildAssocDeletedEventHandler .
• Peer-Peer Association Created - OnPeerAssocCreatedEventHandler .
• Peer-Peer Association Deleted - OnPeerAssocDeletedEventHandler .
• Permission updated - OnPermissionUpdatedEventHandler .
