Method Detail

getConstraintKey

public abstract java.lang.String getConstraintKey()

get the Constraint Key for this Event. The Constraint Key is used to fetch the Filter Constraints that must be evaluated for this Event. The Constraint Key consists of domain_name and type_name of the Event.

Returns:

a String value

toAny

public abstract Any toAny()

Access this NotificationEvent as Any.

Returns:

an Any value

toStructuredEvent

public abstract StructuredEvent toStructuredEvent()

Access this NotificationEvent as StructuredEvent.

Returns:

a StructuredEvent value

getType

public abstract int getType()

get the Type of this NotificationEvent. The value is one of TYPE_ANY, TYPE_STRUCTURED, or TYPE_TYPED.

Returns:

the Type of this NotificationEvent.

reset

public void reset()

Description copied from class: AbstractPoolable

Reset the Object to an initial state. Subclasses should override this method appropiately to reset the instance to an initial state.

Specified by:

reset in class AbstractPoolable

addReference

public void addReference()

Add a reference on this NotificationEvent. After Usage removeReference must be called.

removeReference

protected void removeReference()

release this NotificationEvent. If the internal Refcounter is zero the NotificationEvent is returned to its pool.
