Object management facility which includes a snapshot facility for providing data transfer between two objects.

摘要

A computer having a file management system and a plurality of objects is presented. The file management allows for the coordination the transfer of data between objects (611-614). A link (615 - 617) with a view may be created between child objects (612 - 614) and a parent object (611) as follows. A user specifies to the child object the data to be displayed and to the parent object a location in which the data is to be displayed. The user causes the file management system to link the child object and the parent object, so that link data structure includes a reference name which identifies the link data structure, a reference to the child object, a reference to the parent object and a data identifier which identifies the data to be transferred. Upon request from the parent object, the child object displays the data in the location specified by the parent object. When the file management system receives the request from the parent object it sends a request for the transfer of the data to the child object. This request includes the location where the data is to be displayed and the data identifier.
