Description
luo stands for 'live uo' table, it provides functors that, when called, access the underlying values from the UO table. Thus it provides a tool to pass a UO table variable name to a function and have the value retrieved at a later point in execution.
While similar functionality can be obtain by passing around strings, the live uo methods have the advantage of being of type 'function' and passing argument checks where functions are expected, thus no special string handling needs to be implemented, and misspelled method names raise an immediate error where specified.
Live UO Methods
There is a method for each corresponding name in the UO table. Additionally, the following methods return tables of UO values with a single call:
