Consequences

• Virtual Proxy can:
• Defer creation of RealSubject
• Defer initialization of RealSubject
• Defer copying of RealSubject (copy-on-write)
• Defer all operations on RealSubject (convert to batch stream to be processed later)
• Remote Proxy can also:
• Provide location transparency
• Reduce number of cross-processor trips by caching local info or batching operations
