Expressions describing conditionality or constraints of the AARCHMRS data are expressed using an Abstract Syntax Tree (AST) format. This format mainly stems from two base AST nodes:
To represent expressions such as A ==> B or A == B etc. we use AST.BinaryOp.
To represent expressions such as NOT x, -2 or !(A) we use AST.UnaryOp.
The rest of the AST models are used within these contexts.
Note
While this AST is based on ASL, it is technically not ASL. It is only intended for use in AARCHMRS data.
Please see the ASL reference specification if you need an official ASL AST.
