| 27 | // A semantic action policy holder. This holder stores a reference to ref. | |
| 28 | // act methods are feed with ref and the parse result. | |
| 29 | // | |
| 30 | // (This doc uses convention available in actors.hpp) | |
| 31 | // | |
| 32 | // Constructor: | |
| 33 | // ...(T& ref_); | |
| 34 | // where ref_ is stored. | |
| 35 | // | |
| 36 | // Action calls: | |
| 37 | // act(ref, value); | |
| 38 | // act(ref, first,last); | |
| 39 | // | |
| 40 | // () operators: both | |
