8.6 The Operation Class

The class Operation holds a description of a method in the Java programming language for a remote object.

---

Note - The Operation interface is deprecated as of the Java 2 SDK, Standard Edition, v1.2. The 1.2 stub protocol no longer uses the old RemoteRef.invoke method which takes an Operation as one of its arguments. As of the Java 2 SDK, Standard Edition, v1.2, stubs now use the new invoke method which does not require Operation as a parameter.

package java.rmi.server;

public class Operation {
	public Operation(String op);
	public String getOperation();
	public String toString();
}

An Operation object is typically constructed with the method signature.

The method getOperation returns the contents of the operation descriptor (the value with which it was initialized).

The method toString also returns the string representation of the operation descriptor (typically the method signature).
