Specialized buffer object classes may implement this interface to provide additional information about the contents of the buffer.
SoBufferObject SoCpuBufferCompressed SoCpuBufferUniform
SoBufferPropertiesInterface::SoBufferPropertiesInterface | ( | ) |
Default constructor.
virtual SoBufferPropertiesInterface::~SoBufferPropertiesInterface | ( | ) | [virtual] |
Destructor.
virtual bool SoBufferPropertiesInterface::getMinMax | ( | double & | min, | |
double & | max | |||
) | [pure virtual] |
Get the min and max values in the buffer, if they are known.
Returns FALSE if these values have not been set or computed. Returns TRUE if values are available.
min | user variable to store min value | |
max | user variable to store max value |
Implemented in SoCpuBufferBasicProperty, SoCpuBufferBitSet, SoCpuBufferCompressed, SoCpuBufferFromVolumeReader, and SoCpuBufferUniform.
virtual size_t SoBufferPropertiesInterface::getRealSize | ( | ) | const [pure virtual] |
Returns the real size of the buffer in bytes.
For a standard buffer this is the same as the size. For a compressed buffer this is the compressed size. For a uniform (single value) buffer this is the size of a single value.
Implemented in SoCpuBufferBasicProperty, SoCpuBufferBitSet, SoCpuBufferCompressed, SoCpuBufferFromVolumeReader, and SoCpuBufferUniform.
