Constructor & Destructor Documentation

GridBlindMetaData ( )

inline

Empty constructor.

GridBlindMetaData ( int64_t  dataOffset, uint64_t  valueCount, uint32_t  valueSize, GridBlindDataSemantic  semantic, GridBlindDataClass  dataClass, GridType  dataType  )

inline

GridBlindMetaData ( const GridBlindMetaData &  other )

inline

Copy constructor that resets mDataOffset and zeros out mName.

Member Function Documentation

__hostdev__ const void* blindData ( ) const

inline

returns a const void point to the blind data

Note

assumes that setBlinddData was called

__hostdev__ uint64_t blindDataSize ( ) const

inline

return size in bytes of the blind data represented by this blind meta data

Note

This size includes possible padding for 32 byte alignment. The actual amount of bind data is mValueCount * mValueSize

__hostdev__ const BlindDataT* getBlindData ( ) const

inline

Get a const pointer to the blind data represented by this meta data.

Template Parameters

BlindDataT

Expected value type of the blind data.

Returns

Returns NULL if mGridType!=toGridType<BlindDataT>(), else a const point of type BlindDataT.

Note

Use mDataType=Unknown if BlindDataT is a custom data type unknown to NanoVDB.

__hostdev__ bool isValid ( ) const

inline

return true if this meta data has a valid combination of semantic, class and value tags

Note

this does not check if the mDataOffset has been set!

const GridBlindMetaData& operator= ( const GridBlindMetaData &  rhs )

inline

Copy assignment operator that resets mDataOffset and copies mName.

Parameters

rhs	right-hand instance to copy

Returns

reference to itself

__hostdev__ void setBlindData ( const void *  blindData )

inline

__hostdev__ bool setName ( const char *  name )

inline

Sets the name string.

Parameters

name	c-string source name

Returns

returns false if name has too many characters
