Constructor & Destructor Documentation

ScopeEnv()

morph::ui::detail::ScopeEnv::ScopeEnv ( RtScope const & scope, Bindings const * bindings, Value const * row = nullptr )

inline

Reads scope.

Parameters

scope	The scope.
bindings	The names bound here; may be nullptr.
row	A row to read instead of the scope's (a table's key, evaluated before its row scope exists).
