DISTRIBUTING AND SYNCHRONIZING OBJECTS

摘要

The described embodiments distribute and synchronize objects in a network. More specifically, the described embodiments distribute copies of objects locally (i.e., store copies of objects in local address spaces). By storing a copy of a given object in a local address space, the object's methods may be executed locally, which can help to avoid excessive network traffic associated with remotely executing the object's methods. However, executing an object's methods locally can result in the state of the object (i.e., data associated with the object, etc.) becoming out of sync with other copies of the object in the network. To avoid issues associated with unsynchronized copies of the object in the network, the described embodiments use a policy that specifies conditions under which objects are to be synchronized.

1. A method for synchronizing objects, comprising:
in a computer, performing operations for:
copying an object from a remote computer across a network to said computer, said object being a programming unit that includes executable methods and data operated on by said methods;obtaining a policy for synchronizing said methods and data between said computer and said remote computer, wherein said policy is temporally based; andsynchronizing said methods and data between said computer and said remote computer based on said policy.
