Detailed Description

Large Data Management LDM interface to optimize memory management of tiles .

Specialized buffer object classes may implement this interface to provide additional information about the contents of the buffer.

Constructor & Destructor Documentation

SoBufferPropertiesInterface::SoBufferPropertiesInterface (  ) 

Default constructor.

virtual SoBufferPropertiesInterface::~SoBufferPropertiesInterface (  )  [virtual]

Destructor.


Member Function Documentation

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.

Parameters:
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.
