Detailed Description

A named variable, e.g. "x".

There are two distinct places in which a Variable can appear in the AST. A variable declaration introduces a new variable, and can occur in 3 places: Let-expressions: (Let (x = t) u) Functions: (Function (x : t) u) Self-applicable functions (SFunction (x) t)

If a variable occurs in any other location, it is a reference to an existing variable declaration – e.g. 'x' in (x * y + z). To save space, we don't allocate a separate AST node for variable references; a reference is just a pointer to the original declaration.

SExpr* clang::threadSafety::til::Variable::definition ( )
inline

Return the definition of the variable. For let-vars, this is the setting expression. For function and self parameters, it is the type of the variable.
