One alternative is to do this instead:
BOOST_ENUM_VALUES(BlockType_t, const char*, (SampleIfg)("Sample Interferogram") (SampleSpec)("Sample Spectrum") (SamplePhase)("Sample Phase") (RefIfg)("Reference Interferogram") )
One principle idea of the Boost.Enum library is to hide the fact that integers are really doing the dirty work. I suppose in this case we could expose a 'raw' or 'native' method that would return the index number of the enumeration element. This could then be used for your vector index. Would this work for you?
Yes that would work for me. I took it that the spirit of BOOST_ENUM was indeed to hide the basic type and that you should use BOOST_ENUM_VALUES if you wanted to be sure of the value of each enumeration. There's always a 'but', so mine is that using BOOST_ENUM_VALUES as you suggest requires that the enumeration values start with zero. I think that's most cases.
