ASYNCHRONOUS PROGRAMMING MODEL FOR CONCURRENT WORKFLOW SCENARIOS

摘要

Asynchronous functions in a programming workflow are executed by first storing a context structure comprising workflow-specific global variables and a global-context pointer variable that is a pointer to the context structure. When an asynchronous function is executed, the global-context pointer variable is stored in a local variable and, when the function completes, the global-context pointer variable is restored with the local variable.

1. A method for executing asynchronous functions in a programming workflow, the method comprising:
storing, in a computer memory, a context structure comprising workflow-specific global variables; storing, in the computer memory, a global-context pointer variable comprising a pointer to the context structure; storing the global-context pointer variable in a local variable of an asynchronous function; executing with a computer processor, from a waiting state of the programming workflow, the asynchronous function; and restoring the global-context pointer variable with the local variable.
