43. AST type ussage collection¶
The ast_used module implements type collecting infrasturcture. It allows to determine, if enumeration and structure types are used in the code.
All functions and symbols are in “ast_used” module, use require to get access to it.
require daslib/ast_used
-
OnlyUsedTypes¶
OnlyUsedTypes fields are
st |
table< ast::Structure ?;bool> |
en |
table< ast::Enumeration ?;bool> |
Collection of all structure and enumeration types that are used in the AST.
43.1. Collecting type information¶
-
collect_used_types(vfun: array<Function?> const; vvar: array<Variable?> const; blk: block<(usedTypes:OnlyUsedTypes const):void> const)¶
argument |
argument type |
|---|---|
vfun |
array< ast::Function ?> const |
vvar |
array< ast::Variable ?> const |
blk |
block<(usedTypes: ast_used::OnlyUsedTypes const):void> const |
Goes through list of functions vfun and variables vvar and collects list of which enumeration and structure types are used in them. Calls blk with said list.
