class ObjCAvailabilityCheckExpr

Declaration

class ObjCAvailabilityCheckExpr : public Expr { /* full declaration omitted */ };

Description

A runtime availability query. There are 2 ways to spell this node: Note that we only need to keep track of one \c VersionTuple here, which is the one that corresponds to the current deployment target. This is meant to be used in the condition of an \c if, but it is also usable as top level expressions.
