Conversion of lightweight object to a heavyweight object

摘要

Processing an object that shares a parent with another object is disclosed. An indication is received with respect to an object that shares a parent object instance with one or more other objects that a change associated with the object is to be made to a data comprising the shared parent object instance. The parent object instance is cloned to create a new parent object instance. The new parent object instance is designated as the parent of the object instance.

主权项

1. A system for processing a lightweight composite object that shares a parent with another lightweight composite object, comprising:
a database for storing a lightweight composite object, one or more other lightweight composite objects, and a parent object instance, wherein the lightweight composite object and the one or more other lightweight composite objects share the parent object instance, wherein the lightweight composite object and the one or more other lightweight objects inherit data and behavior from the shared parent object instance, wherein the lightweight composite object and the one or more other lightweight composite objects each comprise a lightweight object instance and a link to the shared parent object instance, wherein the database stores one copy of the shared parent object instance; an interface for receiving an indication that a change is to be made to data associated with the lightweight composite object, wherein the data comprises data of the shared parent object instance; and a processor configured to: clone the parent object instance to create a new parent object instance; and designate the new parent object instance as the parent of the lightweight object instance corresponding to the lightweight composite object.
