Typedefs:

typedef DataT ElementT;: Allow function templates to find type of array.
typedef SArray3dIterC<DataT> IteratorT;: Type of iterator.

Variables:

Methods:

SArray3dC(): Default constructor.
SArray3dC(SizeT dim1,SizeT dim2,SizeT dim3): Constructor.
SArray3dC(const BufferC<DataT> & bf,SizeT size1,SizeT size2,SizeT startOffset = 0,SizeT stride = 0): Constructor using the buffer 'bf'.
This can be used, for example to view a 1d array, as a 3d array. startOffset is the location in the buffer to use as 0,0. If stride is set to zero, size2 is used.
NOT IMPLEMENTED, Will be on request.
SArray3dC<DataT> Copy() const: Copy array.
