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