Applying timed operations to non-timed functions

An apparatus comprising:

• a computer readable storage medium storing a computer readable program executed by a processor, the computer readable program comprising:
• an encapsulation module discovering, by parsing source code, a caller calling a function, wherein the function does not perform timed operations, encapsulating the function in a timed method adapter, wherein the caller calls the timed method adapter in place of the function, and passing the timed method adapter an object and an argument for the function;
• the timed method adapter calling a set invoker, passing the set invoker the object, the function, and the argument for the function;
• the set invoker saving the argument, calling an invoke thread, and returning to the timed method adapter;
• the invoke thread invoking the function and passing the function the object and the argument;
• the timed method adapter further waiting for an execution result from the function and monitoring for an expiration of a timeout, wherein if the function returns the execution result before expiration of the timeout, the timed method adapter returns the execution result to the caller else if the timeout expires before the function returns the execution result, the timed method adapter directs the invoke thread to cancel the function and returns a timeout exception to the caller.

A system comprising:

• a computer readable storage medium storing a computer readable program executed by a processor, the computer readable program comprising:
• an encapsulation module discovering, by parsing source code, a caller calling a function and encapsulating the function in a timed method adapter;
• the caller calling the timed method adapter in place of the function, passing the timed method adapter an object and an argument for the function;
• the timed method adapter calling a set invoker, passing the set invoker the object, the function, and the argument for the function;
• the set invoker saving the argument, calling an invoke thread, and returning to the timed method adapter;
• the invoke thread invoking the function and passing the function the object and the argument;
• the timed method adapter further waiting for an execution result from the function and monitoring for an expiration of a timeout, wherein if the function returns the execution result before expiration of the timeout, the timed method adapter returns the execution result to the caller else if the timeout expires before the function returns the execution result, the timed method adapter directs the invoke thread to cancel the function and returns a timeout exception to the caller.

A method for deploying computer infrastructure, comprising integrating a computer readable storage medium tangibly embodying a computer readable program into a computing system, wherein the program in combination with the computing system performs the following:

• discovering, by parsing source code, a caller calling a function, wherein the function does not perform timed operations;
• encapsulating the function in a timed method adapter with a timeout, wherein the timeout is a time interval;
• replacing the function with the timed method adapter;
• calling the timed method adapter in place of the function from the caller, passing the timed method adapter an object and an argument for the function;
• calling a set invoker from the timed method adapter, passing the set invoker the object, the function, and the argument for the function;
• saving the argument from the set invoker;
• calling an invoke thread from the set invoker;
• returning from the set invoker to the timed method adapter;
• waiting for an execution result from the function at the timed method adapter, monitoring for an expiration of a timeout;
• invoking the function from the invoke thread, passing the function the object and the argument;
• if the function returns the execution result before expiration of the timeout, returning the execution result to the caller;
• and
• if the timeout expires before the function returns the execution result, directing the invoke thread to cancel the function and return a timeout exception to the caller.
