Detailed Description

template<class T>
class itk::ByteSwapper< T >

Perform machine dependent byte swapping.

ByteSwapper is used by I/O classes to perform machine dependent byte swapping. Byte swapping is often used when reading or writing binary files. Files can either be Big Endian (BE) or Little Endian (LE).
