Abstract

Notifying original state listeners within a domain model. Identifying listener registration information pertaining to a listener. Monitoring a hierarchical relationship tree for an observable event, whereby the hierarchical relationship tree includes model objects, and whereby an observable event includes one or more of a change to a model object, an error condition associated with a model object, and the hierarchical relationship tree returning to an original state. Determining that a first observable event to the hierarchical relationship tree has occurred. Transmitting a notification to the listener detailing the occurrence of the first observable event. Determining that a second observable event to the hierarchical relationship tree has occurred. Determining that a third observable event to the hierarchical relationship tree has occurred, whereby the third observable event includes the hierarchical relationship tree returning to an original state. Transmitting a notification to the listener detailing the occurrence of the third observable event.

Claims

1. A method for notifying a listener within a domain model, the method comprising:

registering, by a computer, a listener to a model object based on a plurality of listener registration information, wherein the plurality of listener registration information includes the model object to which the listener will register, a feature of the model object to which the listener will register, and a listener type of the listener, and wherein a list of each listener type is maintained, and wherein registering the listener comprises adding the listener to the list corresponding to the listener type, and wherein the listener receives at least one notification, and wherein the model object is part of a hierarchical relationship tree comprising a plurality of related model objects;

determining that an initial change has occurred to the model object or one of the plurality of related model objects within the hierarchical relationship tree that alters the hierarchical relationship tree from an original state based on a notification algorithm, wherein the notification algorithm determines whether a change alters the hierarchical relationship tree from the original state or returns the hierarchical relationship tree to the original state;

transmitting a first notification to the registered listener based on the determined initial change, wherein the transmitted notification includes a plurality of details corresponding to the determined initial change, and wherein the first notification may be transmitted to the registered listener based on the listener type associated with the registered listener;

displaying a change indicator in a user interface beside the model object and each related model object within the plurality of related model objects affected by the determined initial change;

determining that a subsequent change has occurred to the model object or one of the plurality of related model objects within the hierarchical relationship tree that returns the hierarchical relationship tree to the original state based on the notification algorithm;

transmitting a second notification to the registered listener based on the determined subsequent change detailing the subsequent change has occurred; and

removing the displayed change indicator in the user interface beside the model object and each related model object within the plurality of related model objects affected by the transmitted second notification.
