Constructor Detail

AbstractEventMapper

protected AbstractEventMapper(String id,
                              Properties properties)
                       throws BaseException

id - id

properties - properties

Throws:

Method Detail

getID

public String getID()

Get the mapper's unique system id.

Specified by:

getID in interface IEventMapper

Returns:

mapper's unique system id

getDescription

public String getDescription()

Get the mapper's displayable name.

Specified by:

getDescription in interface IEventMapper

Returns:

mapper's displayable name

getDescription

public String getDescription(Locale locale)

Get the mapper's localized displayable name.

Specified by:

getDescription in interface IEventMapper

Parameters:

locale - locale

Returns:

mapper's localized displayable name

map

public abstract IEvent map(IEvent event)

Map or transform an event prior to sending it to the receiver from one kind to another which then is sent to the receiver. It might be a good idea to put the orginal event in the user defined parameter of the new mapped and sent event.

Specified by:

map in interface IEventMapper

Parameters:

event - event to be mapped

Returns:

mapped event

getEvents

public IEventList getEvents(IEventBroker broker)

Returns a list of mapped event templates for all possible events this mapper can send. The event instances contained in the list are "templates", that means the event parameter is not relevant. An implementation of this method should call the broker and ask it to call all its senders to get the list of all possible event templates which can possibly be handed over to a mapper/receiver. Then the mapper should check, which of these event templates are supported and can be mapped and should return these mapped event templates in a list.

Specified by:

getEvents in interface IEventMapper

Parameters:

broker - broker to be asked for all possible events of all of its senders

Returns:

list of event templates for all possible events this mapper can return in conjunction with the broker
