Using Global Variables

Avoid creating global variables if possible. You can declare global variables in the ‘include hook’. But when using such global variable, make sure that the logic doesn’t make uncertain assumptions about which hooks are invoked at runtime and in which sequence.

Static variables can be used. However, using static variables for optimization may be limited, because a new process may be started for handling a new request (method invocation) that arrives in LN.

Note: Never use any (global) variables that are created and used in the code as generated by the LN Implementation Generator. They are subject to change, and compatibility is never guaranteed.
