javax.jcr.observation .Event

Event

public interface Event (Code)

An event fired by the observation mechanism.

An event may be a method event or a state-change event. If this is a method event then Event.getType will return the constant Event.METHOD_EVENT. If this is a state-change event then Event.getType will return one of the other int constants defined in this interface.

For each state-change event constant, the values returned by the methods Event.getPath , Event.getIdentifier are explained.

For method events further information about the particular method which caused the event can be acquired through Event.getMethod and Event.getMethodInfo .

The value returned by Event.getUserID is always the same as that returned by javax.jcr.Session.getUserID of the session that caused the event.

public String getIdentifier() throws RepositoryException(Code)
	Returns the identifier associated with this event or `null` if this event has no associated identifier. The meaning of the associated identifier depends upon the type of the event. the identifier associated with this event or `null`if this event has no associated identifier. throws: RepositoryException - if an error occurs. since: JCR 2.0

getMethod
public String getMethod() throws RepositoryException(Code)
	If this is a method event, returns the string constant identify the method that caused this event. String throws: RepositoryException -

getMethodInfo
public Map getMethodInfo() throws RepositoryException(Code)
	If this is a method event, returns a `Map` holding the parameters passed to the method that caused this event. The parameters are held in the `Map` as name/value pairs where the name is the string used in this Javadoc to identify the parameter, and the value is the parameter passed.
