## blindData()

const void * blindData | ( |  | ) | const

inline

## blindDataSize()

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

## getBlindData()

template<typename BlindDataT>

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!=mapToGridType<BlindDataT>(), else a const point of type BlindDataT.

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

## isValid()

bool isValid | ( |  | ) | const

inline

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