Detailed Description

template<typename 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).

Constructor & Destructor Documentation

◆ ByteSwapper()

template<typename T >

itk::ByteSwapper< T >::ByteSwapper ( )

protecteddefault

Generic swap method handles type T. The data is swapped and written (in binary) to the ostream given. A total of num values of type T are written and swapped. 2, 4 and 8 byte swapping can be handled. Single byte types are not swapped; others raise an exception. The method is used to swap to and from Big Endian.

◆ ~ByteSwapper()

template<typename T >

itk::ByteSwapper< T >::~ByteSwapper ( )
