◆ JITSymbol() [5/7]
|
inline |
Create a symbol for a definition that doesn't have a known address yet.
- Parameters
-
GetAddress A functor to materialize a definition (fixing the address) on demand.
This constructor allows a JIT layer to provide a reference to a symbol definition without actually materializing the definition up front. The user can materialize the definition at any time by calling the getAddress method.
