Member Function Documentation

◆ allocate()

template<typename T, Index Log2Dim>
bool allocate ( )
inline

◆ data() [1/2]

template<typename T, Index Log2Dim>
LeafBuffer< T, Log2Dim >::ValueType * data ( )
inline

Return a pointer to the array of voxel values.

This method guarantees that the buffer is allocated and loaded.

Warning

◆ data() [2/2]

template<typename T, Index Log2Dim>
const LeafBuffer< T, Log2Dim >::ValueType * data ( ) const
inline

Return a const pointer to the array of voxel values.

This method guarantees that the buffer is allocated and loaded.

Warning
This method should only be used by experts seeking low-level optimizations.

◆ empty()

template<typename T, Index Log2Dim>
bool empty ( ) const
inline

Return true if memory for this buffer has not yet been allocated.

◆ fill()

template<typename T, Index Log2Dim>
void fill ( const ValueType & val)
inline

const ValueType & getValue ( Index i) const
inline

Return a const reference to the i'th element of this buffer.

◆ isOutOfCore()

template<typename T, Index Log2Dim>
bool isOutOfCore ( ) const
inline

Return true if this buffer's values have not yet been read from disk.

◆ memUsage()
