EndianSwapper()

Isis::EndianSwapper::EndianSwapper

(

QString

inputEndian

)

Constructs an EndianSwapper object, determining whether swapping of bytes actually needs to occur and sets the direction of swapping.

Parameters

inputEndian

Byte order of input value (MSB or LSB).

~EndianSwapper()

Isis::EndianSwapper::~EndianSwapper

(

)

Destroys the EndianSwapper object.
