Class EPPBalanceHandler

java.lang.Object

com.verisign.epp.framework.EPPBalanceHandler

All Implemented Interfaces:

EPPEventHandler

Direct Known Subclasses:

BalanceHandler

public abstract class EPPBalanceHandler
extends Object
implements EPPEventHandler

This class provides an interface for handling EPP Balance Commands in a Server implementation. EPPEvents are handled by the handleEvent() method here and routed to the appropriate abstract member function. Subclasses should override the abstract methods to define the desired behavior of a particular command when it is received. A subclassed instance of EPPBalanceHandler should be registered with the EPPDispatcher so that EPPEvents related to the Balance Mapping will be handled there.

Constructor Details

EPPBalanceHandler

public EPPBalanceHandler()

Construct an instance of EPPBalanceHandler. Whenever an EPPBalanceHandler instance is created it also adds EPPBalanceMapFactory to the EPPFactory map factory.

Method Details

getNamespace

public String getNamespace()

Returns the Balance Namespace associated with this handler.

Specified by:

getNamespace in interface EPPEventHandler

Returns:

String the Balance Namespace associated with this handler.

handleEvent

public EPPEventResponse handleEvent(EPPEvent aEvent,
 Object aData)
                             throws EPPEventException

Returns the EPPEventResponse after processing the passed in aEvent. This method receives an EPPEvent and routes it to the appropriate abstract method.

Specified by:

handleEvent in interface EPPEventHandler

Parameters:

aEvent - An EPPEvent that contains the EPPCommand

aData - Any data that a Server needs to send to this EPPBalanceHandler instance.

Returns:

the EPPEventResponse after processing the passed in aEvent.

Throws:

EPPEventException - Thrown if an unrecognized EPPEvent is received

preHandleEvent

protected void preHandleEvent(EPPEvent aEvent,
 Object aData)
                       throws EPPHandleEventException

Handles any common behavior that all Balance commands need to execute before they execute their command specific behavior. The default implementation does nothing.

Parameters:

aEvent - The EPPEvent that is being handled

aData - Any data that a Server needs to send to this EPPBalanceHandler

Throws:

EPPHandleEventException - Thrown if an error condition occurs. It must contain an EPPEventResponse

postHandleEvent

protected void postHandleEvent(EPPEvent aEvent,
 Object aData)
                        throws EPPHandleEventException

Handles any common behavior that all Balance commands need to execute after they execute their command specific behavior. The default implementation does nothing

Parameters:

aEvent - The EPPEvent that is being handled

aData - Any data that a Server needs to send to this EPPBalanceHandler

Throws:

EPPHandleEventException - Thrown if an error condition occurs. It must contain an EPPEventResponse

doBalanceInfo

protected abstract EPPEventResponse doBalanceInfo(EPPEvent aEvent,
 Object aData)

Returns the EPPEventResponse back to the client after processing the passed in aEvent. Invoked when a Balance Info command is received. Subclasses should define the behavior when a Balance Info command is received.

Parameters:

aEvent - The EPPEvent that is being handled

aData - Any data that a Server needs to send to this EPPBalanceHandler

Returns:

the EPPEventResponse back to the client after processing the passed in aEvent.
