template<typename U >

static T npl::NDConstView< T >::castgetStatic ( void *  ptr )

inlinestaticprotected

This is a wrapper function that will be called to safely cast from the underlying type.

Template Parameters

U	Underlying type of pixel, figured out in the constructor

Parameters

ptr	Pointer to memory where the pixel is.

Returns

Correctly cast value

Parameters

index

n-d index to access

Returns

value

Member Data Documentation

template<typename T>

T(* npl::NDConstView< T >::castget) (void *ptr)

protected

Function pointer to the correct function for casting from the underlying type.

Parameters

ptr	location in memory where the pixel is stored

Definition at line 483 of file accessors.h.

template<typename T>

std::shared_ptr<const NDArray> npl::NDConstView< T >::parent

protected

Where to get the dat a from. Also the shared_ptr prevents dealloc.
