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.
