Method Detail

notifyPost

public void notifyPost(Event event,
                       EventPattern pattern,
                       boolean patternDeleted,
                       DataSession session,
                       DataProxy dataspace,
                       ItemData oldValue,
                       ItemBinding oldBinding,
                       ValueBase closure)

Description copied from class: DataCallbackPost

notification of a matched event or pseudo event. As with DataCallback, you pass your own DataCallbackPost subclass as an argument to DataProxy.createSession(equip.data.DataCallback, equip.runtime.ValueBase) when creating a new DataSession. Note that post callbacks may be received AFTER a session or pattern has been deleted (if and only if this is done in a notify callback on the same event). NOTE: this class is not currently (2003-10-16) supported in the C++ version.

Specified by:

notifyPost in class DataCallbackPost

Parameters:

event - The matched event being enacted by the dataspace.

pattern - The pattern that was matched.

patternDeleted - Whether the pattern has been deleted as a result of the event, e.g. matched.

session - The DataSession generating this callback.

dataspace - The local dataspace generating this callback.

oldValue - (for update and delete only) the old value of the data item (before this event was enacted)

oldBinding - (for update and delete only) the old value of the item binding (before this event was enacted)

closure - As provided when the DataSession was created.

notify

public void notify(Event event,
                   EventPattern pattern,
                   boolean patternDeleted,
                   DataSession session,
                   ValueBase closure)

Description copied from class: DataCallback

notification of a matched event or pseudo event. Note, should really have more info here, e.g. dataspace.

Specified by:

notify in class DataCallback

Parameters:

event - The matched event being enacted by the dataspace.

pattern - The pattern that was matched.

patternDeleted - Whether the pattern has been deleted as a result of the event, e.g. matched.

session - The DataSession generating this callback.

closure - As provided when the DataSession was created.
