// Summary:
|
|
// A semantic action policy holder. This holder stores a reference to ref
|
|
// , a const reference to value1_ref and a const reference to value2_ref.
|
|
// Typically, value1_ref is a key and value2_ref is value for associative
|
|
// container operations.
|
|
// act methods are feed with ref, value1_ref, value2_ref. The parse result
|
|
// is not used by this holder.
|
|
//
|
|
// (This doc uses convention available in actors.hpp)
|
|
//
|
|
// Constructor:
|
|
// ...(
|
|
// T& ref_,
|
|
// Value1T const& value1_ref_,
|
|
// Value2T const& value2_ref_ );
|
|
// where ref_, value1_ref and value2_ref_ are stored in the holder.
|
|
//
|
|
// Action calls:
|
|
// act(ref, value1_ref, value2_ref);
|
|
//
|
|
// () operators: both
|
|
