Enumerations

Enumerations are sets of related integer constants, where each value has a name. Studio has built-in support for enumerations (sequential and non-sequential). These are some properties of enumerations:

Type safe: The compiler checks that the values belong to the enumeration.
User-Friendly: Understanding a piece of code that uses them is easier. Enumerations have a name that indicates what they represent.
Improved Performance: Comparison of enumeration values is reduced to a comparison between integers.

Using Enumerations

Enumerations can be used with a qualified name:

action = Action.SKI

or without qualification, when the type of the enumeration can be inferred from the context:

action = SKIP

To check the value of an Enumeration, you can use the is operator:

if action is CANCEL then
//Do something
end

or if you prefer, the multi-path conditional statement:

case action
when SKIP then
// Process SKIP
when CANCEL then
// Process CANCEL
else
// Handle all other values
end
