Detailed Description

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

A generic accessor that works for any instance layout. GenericAccessors. While useful, these accessors are generally more expensive and should be used with caution. A read/write operation via this accessor could potentially result in a network transaction, assuming the data is stored on a remote node

GenericAccessor() [2/3]

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

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

Construct a GenericAccessor for the specified instance and field. Implicitly tries to cover the entire instance's domain.

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.

GenericAccessor() [3/3]

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

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

Construct a GenericAccessor for the specified instance and field. Limits the domain to the specified subrectangle.

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.
