Object reference in a system
View Patent ↗A system can be configured using configuration objects that have the ability to refer to one another. In one embodiment, the present invention includes such a system having a plurality of objects used to configure the system, each object having a uniform resource identifier (URI), and an object reference table to enable the plurality of objects to reference each other without using URIs.
1. A method for updating an object reference table comprising a plurality of records, wherein each record represents an object and comprises an object identifier (OID) field and a uniform resource identifier (URI) field, and wherein an object is electronic data that encodes configuration information for a processor-based system, the method comprising:
using a processor to determine that an object has been deleted, or to determine that an object has been created, or to determine that an object's URI has changed, wherein the object is associated with an OID and a URI;
responsive to determining that the object has been deleted:
determining a record in the object reference table that corresponds to the deleted object, wherein a reference identifier associated with the record matches a reference identifier associated with the object; and
deleting the OID field value of the record or setting the OID field value of the record to null;
responsive to determining that the object has been created:
determining a record in the object reference table that corresponds to the created object, wherein the URI associated with the record matches the URI associated with the created object; and
setting the OID field value of the record to the OID associated with the created object; and
responsive to determining that the object's URI has changed:
determining a record in the object reference table that corresponds to the changed object, wherein the OID associated with the record matches the OID associated with the changed object; and
setting the URI field value of the record to the URI associated with the changed object.
2. A computer system for updating an object reference table comprising a plurality of records, wherein each record represents an object and comprises an object identifier (OID) field and a uniform resource identifier (URI) field, and wherein an object is electronic data that encodes configuration information for a processor-based system, the computer system comprising a processor configured to perform a method, the method comprising:
determining that an object has been deleted, or determining that an object has been created, or determining that an object's URI has changed, wherein the object is associated with an OID and a URI;
responsive to determining that the object has been deleted:
determining a record in the object reference table that corresponds to the deleted object, wherein a reference identifier associated with the record matches a reference identifier associated with the object; and
deleting the OID field value of the record or setting the OID field value of the record to null;
responsive to determining that the object has been created:
determining a record in the object reference table that corresponds to the created object, wherein the URI associated with the record matches the URI associated with the created object; and
setting the OID field value of the record to the OID associated with the created object; and
responsive to determining that the object's URI has changed:
determining a record in the object reference table that corresponds to the changed object, wherein the OID associated with the record matches the OID associated with the changed object; and
setting the URI field value of the record to the URI associated with the changed object.
3. A computer-readable storage medium containing a computer program product for updating an object reference table comprising a plurality of records, wherein each record represents an object and comprises an object identifier (OID) field and a uniform resource identifier (URI) field, and wherein an object is electronic data that encodes configuration information for a processor-based system, the computer program product comprising computer program code for:
determining that an object has been deleted, or determining that an object has been created, or determining that an object's URI has changed, wherein the object is associated with an OID and a URI;
responsive to determining that the object has been deleted:
determining a record in the object reference table that corresponds to the deleted object, wherein a reference identifier associated with the record matches a reference identifier associated with the object; and
deleting the OID field value of the record or setting the OID field value of the record to null;
responsive to determining that the object has been created:
determining a record in the object reference table that corresponds to the created object, wherein the URI associated with the record matches the URI associated with the created object; and
setting the OID field value of the record to the OID associated with the created object; and
responsive to determining that the object's URI has changed:
determining a record in the object reference table that corresponds to the changed object, wherein the OID associated with the record matches the OID associated with the changed object; and
setting the URI field value of the record to the URI associated with the changed object.
4. A method for updating an object reference table comprising a plurality of records, wherein each record represents an object and comprises an object identifier (OID) field and a uniform resource identifier (URI) field, and wherein an object is electronic data that encodes configuration information for a processor-based system, the method comprising:
using a processor to determine that an object has been created, wherein the object is associated with an OID and a URI; and
responsive to determining that the object has been created:
determining a record in the object reference table that corresponds to the created object, wherein the URI associated with the record matches the URI associated with the created object; and
setting the OID field value of the record to the OID associated with the created object.
5. The method of claim 4 , wherein the object that has been created is an imported object.
6. The method of claim 4 , wherein the object that has been created is a re-activated object.
7. The method of claim 4 , further comprising:
determining that an object has been deleted, wherein the object is associated with an OID and a URI; and
responsive to determining that the object has been deleted:
determining a record in the object reference table that corresponds to the deleted object, wherein a reference identifier associated with the record matches a reference identifier associated with the object; and
deleting the OID field value of the record or setting the OID field value of the record to null;
8. The method of claim 7 , wherein the reference identifier associated with the object is globally unique.
9. The method of claim 7 , wherein the reference identifier associated with the object is used by another object to refer to the object with which the reference identifier is associated.
10. The method of claim 4 , further comprising:
determining that an object's URI has changed, wherein the object is associated with an OID and a URI; and
responsive to determining that the object's URI has changed:
determining a record in the object reference table that corresponds to the changed object, wherein the OID associated with the record matches the OID associated with the changed object; and
setting the URI field value of the record to the URI associated with the changed object.
