Member Enumeration Documentation

enum GU_AttributeSwap::SwapMethod

Operation to perform. Move will remove the source. Note the point attribute P cannot be moved so it will be instead silently copied. Swap exchanges the pair. If destination is missing, it is copied.

enum GU_AttributeSwap::TypeInfo

What to do about typeinfos. When stashing attributes one often wants to clear the transform type so succeeding deformers don't also change your stashed values, this becomes the preserve-dest. OTOH, when duplicating, you want the copy to have the source typeinfo. This is ignored for swapping.

Member Function Documentation

static bool GU_AttributeSwap::swapAttribute ( GU_Detail *  gdp, SwapMethod  method, TypeInfo  typeinfo, GA_AttributeOwner  owner, const UT_StringRef &  srcname, const UT_StringRef &  dstname  )

Does the method to the two named attributes. If swapping a missing attribute, will first create it. source attribute is assumed to exist. Returns false if failed for some reason; note there are special rules about how P can change. You must invoke gdp->refreshCachedAttributes() if there is a risk you changed the P attribute!
