Abstract

A method and apparatus for asynchronously calling and implementing objects is disclosed. Object calls to perform an operation are performed asynchronously by calling the appropriate stub function from the client application and passing in the object reference, input parameters, and a pointer to a completion routine. The object reference, input parameters, and completion routine address are provided to a client-side execution environment. The client-side execution environment stores the completion routine address and transmits the input parameters to a server-side execution environment. The server-side execution environment calls a method in the server application that implements the requested operation. The server application performs the requested operation. Once the call has been responded to, the client-side execution environment calls the completion routine and passes it the output parameters to the requested operation. The client application can continue performing other asynchronous operations before the completion routine is called. To asynchronously implement an object that has been called, the appropriate method function in the server application is called which, in turn, calls an asynchronous operation. Once the asynchronous operation returns, the application responds to the client application.
