Method and apparatus for fast, local CORBA object references

A method for creating a first object reference associated with a servant object in an object-based system, the method comprising:

• determining when a first client representation which includes a first pointer to the servant object is valid;
• creating a second client representation when it is determined that the first client representation is not valid, the second client representation including a second pointer to the servant object;
• and
• creating an association between the first object reference and the second client reference, wherein the first object reference is arranged to invoke the servant object, the first object reference being local to the servant object.

A method for processing a request to create a local-only object reference in an object-based system, the method comprising:

• receiving the request to create the local only object reference, the request being received on a servant object;
• requesting a first client representation from a server representation;
• determining whether the first client representation is valid;
• and
• creating a new client representation when it is determined that the first client representation is not valid.

A customization object in an object-based system, the customization object being arranged to be invoked only by a client which is in a first process with the customization object, the customization object comprising:

• a pre-local method arranged to store a copy of a representation of the customization object;
• a post-local method, wherein the post-local method is associated with the pre-local method;
• and
• a servant method arranged to check for a pointer from the client to the customization object, wherein the pointer is arranged to indicate whether the customization object is suitable for invocation.

A computer system arranged to create an object reference, wherein the object reference is associated with a local-only servant object, the computer system comprising:

• a processor;
• a first base class arranged to create a first object that represents the object reference, wherein the first base class is associated with an object request broker;
• a local-only create closure;
• and
• a second base class, the second base class including an operation that is arranged to be called with the local-only create closure, wherein the operation is arranged to create a server-side representation associated with the local-only servant object, the server-side representation being arranged to be stored in the first object that represents the object reference.

A computer program product for creating a first object reference associated with a servant object in an object-based system, wherein the first object reference is arranged to invoke the servant object, the first object reference being local to the servant object, the computer program product comprising:

• computer code that determines when a first client representation which includes a first pointer to the servant object is valid;
• computer code that creates a second client representation when it is determined that the first client representation is not valid, the second client representation includes a second pointer to the servant object;
• and
• a computer readable medium that stores the computer codes.

A computer program product for creating an object reference, wherein the object reference is associated with a local-only servant object, the method comprising:

• computer code that implements a first base class to create a first object that represents the object reference, wherein the first base class is associated with an object request broker;
• computer code that obtains a local-only create closure;
• computer code that calls an operation on a second base class, the operation being called with the local-only create closure, wherein the operation is arranged to create a server-side representation associated with the local-only servant object, the server-side representation being arranged to be stored in the first object that represents the object reference;
• and
• a computer readable medium that stores the computer codes.
