Detailed Description

template<typename T>
class xgboost::common::RefResourceView< T >

A vector-like type that holds a reference counted resource.

The vector size is immutable after construction. This way we can swap the underlying resource when needed.

Constructor & Destructor Documentation

template<typename T >

xgboost::common::RefResourceView< T >::RefResourceView	(	value_type *	ptr,
		size_type	n,
		std::shared_ptr< common::ResourceHandler >	mem,
		T const &	init
	)

inline

Construct a view on ptr with length n.

The ptr is held by the mem resource.

Parameters

ptr	The pointer to view.
n	The length of the view.
mem	The owner of the pointer.
init	Initialize the view with this value.
