◆ Reset()

virtual void LIBEVAL::CONTEXT::Reset ( )
inlinevirtual

Release every value allocated by the previous evaluation and rewind the stack so the same CONTEXT can be reused for another Run() without being reconstructed.

This keeps the owned- value vector's buffer allocated, so a reused context performs zero heap allocation for the common evaluation. Overrides must chain to this base after rewinding their own per-run state.

Reimplemented in PCBEXPR_CONTEXT.
