Hello all,
I am writing a gui which controls external hardware thru an interface protocol.
Currently i defined all my control commands into a structure with common read and write functions that are called via function handles.
This works great!
Except to get it to work the way I wanted it to work i needed to use a global variable, and dynamically define a variable. Both of which everyone tells me I am a horrible person for doing.
But i successfully impletmented this with 50 or so Commands for several 'B' level module units, i can call each command just by typing the desired structure element .in this example CallOutput = A.B.C1(1,4) will perform my hardware call and set A.B.C1 to the same value simultaneously.
Thus allowing me to avoid typing 5 or 6 lines of code in the main script everytime i want to issue a command or pull a state from the hardware.
But also allowing me to just define the parameters of each command in the structure then pass those parameters to the read function, rather than haveing to write a different read function for each command.
A.B.C2 = @(x,y) Test(x,y,A,'B','C1');
A.D.C2 = @(x,y) Test(x,y,A,'D','C1');
CallOutput1 = A.B.C2(1,4)
CallOutput2 = A.D.C2(5,6)
function Z=Test(X,Y,A,Module,Command)
While this works, the issue i face now is that matlab shows
"Warning: The value of local variables may have been changed to match the globals. Future versions of MATLAB will require that you declare a variable to be global before you use that variable. "
A) I recognize using a global is not the best of ideas
B) i dont want to get scewed later if matlab changes how the globals work
So now you have the background, lets get to my actual question.
It has come to my attention that i can maybe create a class and achieve the same functionality, but without the use of globals.
however, I am struggling with determining how the class functionality mirrors the structure/functionality I have already created.
I really like my ability to call what i need in the form of a structure, where the commands all together, but segregated into their own related groupings via different levels of the structure.
Classdef seems to have a single layer of depth within it while my structure has multiple layers A.B.C, etc.
Creating a subclass seems to want me to create a new file.
I am simply not seeing how i can translate my current structure into a class.
Do i need to define a new classdef file for everysingle command i need to use? (that would be C level in the above example code?) this would result is hundreds of individual files.. Which doesnt seem like the way its supposed to work. Thus i must be missing something.
Can someone help me by looking at the above code and indicating how it could be re-written into a class?
Once i see an example of what i need to do, i should be able to carry myself the rest of the way. its just this first step i cant wrap my brain around.
