Method for efficient location of corba objects based on an unmarshaled object key in a request
View Patent ↗Disclosed are methods and threads for responding to a request to perform an operation on a server object as may be provided in software form within an object request broker (ORB) server library or an ORB server. The specified object is identified by a marshaled object key in a conventional manner. The method improves upon prior art techniques by directly locating the object using the marshaled object key free of any unmarshaling step. The specified operation can then be invoked on the located object. The method applies to both in-process and out-of-process requests. In a preferred implementation, the marshaled object key is utilized as a hash key to directly access a pointer to the object.
1. A computer implemented system for handling a request to perform an operation on one of a plurality of computer server objects, each of the plurality of computer server objects comprising an associated object key, the computer implemented system comprising:
a computer comprising a processor, the processor configured to:
perform processing associated with receiving a first request from a first computer client, the first request comprising a first requested operation to be performed on a first target object and an activation record, wherein the activation record includes a pointer to a location of the first target object;
perform processing associated with locating the first target object by using the activation record;
perform processing associated with invoking the first requested operation on the first target object;
perform processing associated with receiving a second request from a second computer client, the second request comprising a marshaled object key and a second requested operation to be performed on a second target object, wherein the second target object includes a first associated object key, and wherein the marshaled object key includes a byte array computed by transforming the first associated object key;
perform processing associated with unmarshaling the marshaled object key from the second request to create an unmarshaled object key;
perform processing associated with locating the second target object by using the unmarshaled object key to traverse the plurality of objects;
perform processing associated with creating an entry in a table associating the marshaled object key with the second target object after locating the second target object;
perform processing associated with invoking the second requested operation on the second target object;
perform processing associated with receiving a third request from a third computer client, the third request comprising the marshaled object key and a third requested operation to be performed on the second target object;
perform processing associated with locating the second target object by using the marshaled object key as a key for the table; and
perform processing associated with invoking the third requested operation on the second target object after locating the second target object.
