Constructor & Destructor Documentation

template<typename T>

lama::LAMAArrayView< T >::LAMAArrayView

(

LAMAArray< T > &

array

)

Constructs a view into the whole passed LAMAArray.

Parameters:

[in,out]

array

the array to get a view into.

References lama::_LAMAArray::constFlag, and LAMA_THROWEXCEPTION.

template<typename T>

lama::LAMAArrayView< T >::LAMAArrayView	(	LAMAArray< T > &	array,

const

Checks if the LAMAArray referenced by other is not the same than the LAMAArray reference by this.

Checks if the LAMAArray referenced by other is not the same than the LAMAArray reference by this. CAVEAT: It is only checked if the LAMAArrays are not the same. Size and offset of the views are not checked for inequality.

Parameters:

[in]

other

Returns:

if this and other are referencing different LAMAArrays.

Checks if the LAMAArray referenced by other is not the same than the LAMAArray reference by this. CAVEAT: It is only checked if the LAMAArrays are not the same. Size and offset of the views are not checked for inequality.

Parameters:

[in]

other
