◆ doubleCopy()

void nidas::util::NoFlipConverter::doubleCopy	(	const double &	,
		void *	) const

inlinevirtual

Copy 8 byte double to the given address, doing endian conversion.

Pointer to address does not need to be 8-byte aligned.

Implements nidas::util::EndianConverter.

inlinevirtual

Implements nidas::util::EndianConverter.

◆ doubleValue() [2/2]

double nidas::util::NoFlipConverter::doubleValue ( const void * ) const

inlinevirtual

Get 8 byte double at address, do endian conversion.

Pointer to address does not need to be 8-byte aligned.

Implements nidas::util::EndianConverter.

◆ floatCopy()

void nidas::util::NoFlipConverter::floatCopy	(	const float &	,
		void *	) const

inlinevirtual

Copy 4 byte float to the given address, doing endian conversion.

Pointer to address does not need to be 4-byte aligned.

Implements nidas::util::EndianConverter.

◆ floatValue() [1/2]

float nidas::util::NoFlipConverter::floatValue ( const float & p ) const

inlinevirtual

Implements nidas::util::EndianConverter.

◆ floatValue() [2/2]

float nidas::util::NoFlipConverter::floatValue ( const void * ) const

inlinevirtual

Get 4 byte float at address, do endian conversion.

Pointer to address does not need to be 4-byte aligned.

◆ getConverter() [1/2]

const EndianConverter * EndianConverter::getConverter ( EndianConverter::endianness input )

staticinherited

Return an EndianConverter for converting from an endian represenation to the endian representation of th host.

If both are the same, then the converter that is returned just does memcpy's and does not change the representation. It is a const pointer since all its methods are const, and the pointer is owned by EndianConverter.

◆ getConverter() [2/2]

const EndianConverter * EndianConverter::getConverter	(	EndianConverter::endianness	input,
