class blark.transform.Action(name: Token, body: StatementList | None, meta: Meta | None = None)[source]

Bases: object

A full, named action declaration.

Actions belong to function blocks. Actions may not contain variable blocks, but may contain an implementation. Variable references are assumed to be from the local namespace (i.e., the owner function block) or in the global scope.

Examples:

ACTION ActName
END_ACTION

ACTION ActName
    iValue := iValue + 2;
END_ACTION
