Detailed Description

template<typename Dest, ShDataType DestDT, typename Src, ShDataType SrcDT>
struct SH::ShDataVariantCast< Dest, DestDT, Src, SrcDT >

Handles casting between S and D storage types.

The actual data cast will have type ShHostType<SRC> to ShHostType<DEST> and may have some extra conversion code (e.g. clamping) applied in addition to the default C cast for those types.

Member Function Documentation

template<typename Dest, ShDataType DestDT, typename Src, ShDataType SrcDT> void SH::ShDataVariantCast< Dest, DestDT, Src, SrcDT >::doCast (  ShVariant *  dest, const ShVariant *  src )  const [virtual]

Casts data from src into dest. src must have Src value type and SrcDT data type. dest similarly must match Dest and DestDT. Also, must guarantee dest != src (it will work if they are the same but what a waste...) Implements SH::ShVariantCast.
