18 | // Summary: | |
19 | // A semantic action policy holder. This holder stores a reference to ref | |
20 | // , a const reference to value1_ref and a const reference to value2_ref. | |
21 | // Typically, value1_ref is a key and value2_ref is value for associative | |
22 | // container operations. | |
23 | // act methods are feed with ref, value1_ref, value2_ref. The parse result | |
24 | // is not used by this holder. | |
25 | // | |
26 | // (This doc uses convention available in actors.hpp) | |
27 | // | |
28 | // Constructor: | |
29 | // ...( | |
30 | // T& ref_, | |
31 | // Value1T const& value1_ref_, | |
32 | // Value2T const& value2_ref_ ); | |
33 | // where ref_, value1_ref and value2_ref_ are stored in the holder. | |
34 | // | |
35 | // Action calls: | |
36 | // act(ref, value1_ref, value2_ref); | |
37 | // | |
38 | // () operators: both | |
