- The pTraits_cmptType returns the data type of 'cmptType' (for
arithmetic and VectorSpace types) or is simply a pass-through.
This can be combined with the pTraits_nComponents for casting.
For example,
function
(
reinterpret_cast<pTraits_cmptType<Type>::type*>(buf.data()),
(buf.size()/pTraits_nComponents<Type>::value)
);
ENH: extend Foam::identityOp so support array indexing (pass-through)
