Detailed Description

template<typename FT, int N, typename T = int>
class Realm::AffineAccessor< FT, N, T >

An accessor that works for any instance layout that can be linearized using an affine transformation. AffineAccessors are generally more efficient than GenericAccessors, but are only applicable to a subset of instance layouts. The random-access look-ups are O(1) in the size of the instance.

AffineAccessor() [2/7]

template<typename FT , int N, typename T = int>

Realm::AffineAccessor< FT, N, T >::AffineAccessor	(	RegionInstance	inst,
		FieldID	field_id,
		size_t	subfield_offset = 0
	)

Construct an AffineAccessor for the specified instance and field. Implicitly tries to cover the entire instance's domain. NOTE: this constructor will die if the instance is not compatible with AffineAccessor. Call is_compatible(...) first if you're not sure.

Parameters

inst	RegionInstance to construct accessor for.
field_id	FieldID of field to construct accessor for.
subfield_offset	Offset of subfield to construct accessor for.

AffineAccessor() [3/7]

template<typename FT , int N, typename T = int>

Realm::AffineAccessor< FT, N, T >::AffineAccessor	(	RegionInstance	inst,
		FieldID	field_id,
		const Rect< N, T > &	subrect,
		size_t	subfield_offset = 0
	)

Construct an AffineAccessor for the specified instance and field. Limits the domain to the specified subrectangle. NOTE: this constructor will die if the instance is not compatible with AffineAccessor. Call is_compatible(...) first if you're not sure.

Parameters

inst	RegionInstance to construct accessor for.
field_id	FieldID of field to construct accessor for.
subrect	Subrectangle to limit domain to.
subfield_offset	Offset of subfield to construct accessor for.

AffineAccessor() [4/7]

template<typename FT , int N, typename T = int>

template<int N2, typename T2 >

Realm::AffineAccessor< FT, N, T >::AffineAccessor	(	RegionInstance	inst,
		const Matrix< N2, N, T2 > &	transform,
		const Point< N2, T2 > &	offset,
		FieldID	field_id,
		size_t	subfield_offset = 0
	)

Construct an AffineAccessor for the specified instance, field, and coordinate transform.

Parameters

inst	RegionInstance to construct accessor for.
transform	Affine transform to apply to coordinates.
offset	Offset to apply to coordinates.
field_id	FieldID of field to construct accessor for.
subfield_offset	Offset of subfield to construct accessor for.
