# Applicability
|
||
|
|
|
||
|
|
* Protection proxy limits access to the real subject.
|
||
|
|
* Virtual proxies are used when an object is expensive to instantiate.
|
||
|
|
* Caching proxies are used to cache expensive calls to the real subject.
|
||
|
|
* Remote proxies are used in distributed object communication.
|
||
|
|
* Smart proxies are used to implement reference counting and log calls to the object.
