| // Summary: |
| // A semantic action policy holder. This holder stores a reference to ref |
| // and a const reference to value_ref. |
| // act methods are feed with ref and value_ref. The parse result is |
| // not used by this holder. |
| // |
| // (This doc uses convention available in actors.hpp) |
| // |
| // Constructor: |
| // ...(T& ref_, ValueT const& value_ref_); |
| // where ref_ and value_ref_ are stored in the holder. |
| // |
| // Action calls: |
| // act(ref, value_ref); |
| // |
| // () operators: both |
