Constructor & Destructor Documentation

GU_SubDivPacking::GU_SubDivPacking ( )

Default constructor.

GU_SubDivPacking::GU_SubDivPacking ( const GA_AttributeDict dict)

Constructor which builds all float attributes for a dictionary.

GU_SubDivPacking::GU_SubDivPacking ( const GU_SubDivPacking src)

Copy constructor.

GU_SubDivPacking::~GU_SubDivPacking ( )

Destructor.

Member Function Documentation

void GU_SubDivPacking::addAttribute ( GA_Attribute atr,
bool  check_dups,
int  tuple_size = -1 
)

Add a single attribute. If a tuple size is specified, it will override the tuple size fo the attribute. Tuple sizes must be <= the actual attribute tuple size.

void GU_SubDivPacking::addFloatAttributes ( const GA_AttributeDict dict)

Add all float attributes from the given dictionary.

void GU_SubDivPacking::clear ( )

Clear the packing tables.

int GU_SubDivPacking::entries ( void  ) const
inline

Number of attributes.

Definition at line 62 of file GU_SubDivPacking.h.

int GU_SubDivPacking::getCount ( ) const
inline

Number of floats required for the packed array.

Definition at line 65 of file GU_SubDivPacking.h.

const UT_StringArray& GU_SubDivPacking::getNames ( ) const
inline

Offset array into the packed array. This is the offset (not the byte-count)

Definition at line 69 of file GU_SubDivPacking.h.

const UT_IntArray& GU_SubDivPacking::getOffsets ( ) const
inline

Offset array into the packed array. This is the offset (not the byte-count)

Definition at line 73 of file GU_SubDivPacking.h.

int GU_SubDivPacking::getPackedOffset ( const GA_Attribute atr) const

Get the attribute offset (i.e. offset into the packed data)

const UT_IntArray& GU_SubDivPacking::getSizes ( ) const
inline

Number of floats for each attribute (in floats, not bytes)

Definition at line 76 of file GU_SubDivPacking.h.

GU_SubDivPacking& GU_SubDivPacking::operator= ( const GU_SubDivPacking src)

Assignment operator.

template<typename T >
void GU_SubDivPacking::packFloats ( T data,
GA_Offset  off 
) const

Pack floats from an object's attributes into a packed buffer.

template<typename T >
void GU_SubDivPacking::unpackFloats ( GA_Offset  off,
const T data 
) const

Unpack data in the buffer into the object's attributes.
