Global object system

A computer-implemented method for sharing objects in a designer environment, the method comprising:

• requesting a global object that derives from a type, wherein the global object is available to all designers in a development project;
• identifying a global object provider capable of generating the requested global object, wherein a global object service identifies the global object provider from a list;
• generating the global object;
• delivering the global object;
• determining if the delivered global object is serializable;
• retaining or discarding the delivered global object based in part of the determination;
• raising a pair of Changing and Changed events that cause the global object service running on a designer to announce to any references of a data source to update to a new value;
• maintaining a plurality of global object providers, the plurality of global object providers maintained in a factory, wherein the factory is remote from the global object service;
• generating a query of the factory to facilitate identification of the global object provider from the plurality of global object providers;
• registering the global object;
• maintaining a table that includes the global object provider capable of generating the global object from a predefined type;
• updating the table as a result from the query of the factory;
• and
• updating the global object in response to a change.

A system that facilitates employing a global object in a designer environment, the system stored in a computer readable storage medium, comprising;

• means for requesting a global object that derives from a type, wherein the global object is available to all designers in a development project;
• means for identifying a global object provider capable of generating the requested global object, wherein a global object service identifies the global object provider from a list;
• means for generating the global object that derives from the type;
• means for delivering the global object that derives from the type;
• means for raising a pair of Changing and Changed events that cause the global object service running on a designer to announce to any references of a data source to update to a new value;
• means for identifying the global object provider from a plurality of providers in a factory, wherein the factory is remote from the global object service;
• means for automating the request for the global object based upon an inference;
• means for registering the global object that derives from the type;
• means for maintaining a table that includes the global object provider capable of generating the global object from a predefined type;
• means for updating the table as a result from the query of the factory;
• and
• means for updating the global object in response to a change.

A computer implemented system stored in a computer readable storage medium, that facilitates obtaining global objects in a designer environment, comprising the following computer executable components:

• a global object service component that maintains a table of one or more global object provider components, the global object provider components are capable of generating global objects that derive from a predefined type;
• a global object provider factory component that supplies the one or more global object provider components to the global object service component, the global object provider factory component is located remote from the global object service component, the one or more global object provider components comprising the global objects and a metadata component that corresponds to at least one of the global objects, wherein the global object is available to all designers in a development project and the global object raises a pair of Changing and Changed events that cause a global object service running on the designer to announce to a reference of a data source to update to a new value;
• one or more global object attribute components that declare the one or more global object provider components;
• a query component that generates a query to identify the one or more global object provider components from the global object provider factory component, wherein the table is updated as a result from the query of and the global objects are updated in response to a change;
• and
• an interface component that facilitates registration of the global objects.
