Details
This function is useful for aliasing attributes to improve execution speed. Calling the function created with
makegetter() executes faster than accessing the attribute directly.
Creating a getter function is only useful if it is going to be called several times. Otherwise, the overhead of
creating the getter function outweighs the overhead of accessing the attribute directly.
Example
getlevel = makegetter(smua.source, "levelv")
v = getlevel()
Creates a getter function called
getlevel.
When getlevel() is called, it
returns the value of
smua.source.levelv.

Details
This function is useful for aliasing attributes to improve execution speed. Calling the setter function will execute
faster than accessing the attribute directly.
Creating a setter function is only useful if it is going to be called several times. If you are not calling the
setter function several times, it is more efficient to access the attribute directly.
Example
setlevel = makesetter(smua.source, "levelv")
for v = 1, 10 do
setlevel(v)
end
Creates a setter function called
setlevel.
Using setlevel() in the loop
sets the value of
smua.source.levelv,
performing a source sweep.
