Interface CommandCaller

All Known Subinterfaces:

CacheableCommand

All Known Implementing Classes:

CacheableCommandImpl

---

public interface CommandCaller

This interface allows the caller of a command to have additional invalidation dependencies added by this command. If the caller is a cacheable JSP or command, then it sets an object that supports this interface on the command that is called using the CacheableCommand.setCaller method. Every CacheableCommand is a CommandCaller. When the client is a command, it would call the following:

     command.setCaller(this);

The request object for a JSP/Servlet is a CommandCaller. When the client is a JSP/Servlet, it would call the following:

     command.setCaller(request);

The called command gets the caller via the CacheableCommand.getCaller method, and uses this interface to add the dependencies.

See the white paper for more information.
