Ranges and index space identifiers

Classes

group<dimensions>	The cl::sycl::group object is a container for all information about a work group. The cl::sycl::group object is used within the parallel_for_work_group function. The cl::sycl::group object can return information about the local and global sizes of an enqueued nd-range as well as the number of groups and the current group id.
h_item<dimensions>	Identifies an instance of a parallel_for_work_item function object executing at each point in a local range passed to a parallel_for_work_item call.
id<1>	Implementation of id for 1 dimension
id<2>	Implementation of id for 2 dimensions
id<3>	Implementation of id for 3 dimensions
id<dimensions>	base class which the other versions implements specialisations of
item<dimensions, with_offset>	The cl::sycl::item object is a container for all information about a work item. The cl::sycl::item object is used within the handler::parallel_for and information about the local and global sizes of an enqueued nd_range as well as the local and global ids of the work item. item is a derived class of detail::item_base, which is a non-templated class implementing most of the functionality of cl::sycl::item.
nd_item<dimensions>	The cl::sycl::nd_item object is a container for all information about a work-item.
nd_range<dimensions>	Implements the nd_range class of the SYCL specification. An nd_range contains a global and a local range and an offset.
range<1>	1 dimension range definition.
range<2>	2 dimension range definition.
range<3>	3 dimension range definition.
range<dimensions>	range representation of a 1, 2 or 3 dimensional range. A range represents the size of each dimension of the index space.
