Backend decorator
1min
The backend decorator tells the platform what you want to do with the values stored inside the variables used by your custom action.
The IOProperty property allows you to choose one of four possible directions, that will give you more control on over your custom action:
The most useful are Input and Output. While using Input the custom action expects to receive the value from the user and with Output it will return a value that could be one or more inputs that were used internally.
The None option is the default if the IOProperty is not mentioned.
The InputOutput option is used when a property needs to be both input and output, because it must first receive a value before it uses it in the backend.
