Method and apparatus for efficient programming of electronic payment processing

A device, comprising one or more processors and a memory storing executable instructions executable by the one or more processors to perform acts comprising:

• receiving a plurality of programming language-based descriptions each describing a distinct functional operation of a plurality of functional operations usable to implement an electronic payment process;
• compiling each of the plurality of programming language-based description into a distinct computer-executable code segment of a plurality of code segments, wherein the plurality of code segments correspond to a plurality of states of a finite state machine;
• determining a plurality of transition relationships between states of the plurality of states based on a logic flow of steps of the electronic payment process;
• generating a state transition table based, at least in part, on the plurality of states and the transition relationship between the states;
• and
• configuring the finite state machine using the state transition table at a runtime of an electronic payment system that implements the electronic payment process.

A non-transitory computer-readable storage medium storing contents that, when executed by one or more processors, cause the one or more processors to perform acts comprising:

• receiving a plurality of programming language-based descriptions each describing a distinct functional operation of a plurality of functional operations usable to implement an electronic payment process;
• compiling each of the plurality of programming language-based description into a distinct computer-executable code segment of a plurality of code segments, wherein the plurality of code segments correspond to a plurality of states of a finite state machine;
• determining a plurality of transition relationships between states of the plurality of states based on a logic flow of steps of the electronic payment process;
• generating a state transition table based, at least in part, on the plurality of states and the transition relationship between the states;
• and
• configuring the finite state machine using the state transition table at a runtime of an electronic payment system that implements the electronic payment process.
