Detailed Description

template<typename TArrayExtents, typename TRecordDim, typename TSelectorForMapping1, template< typename... > typename MappingTemplate1, template< typename... > typename MappingTemplate2, bool SeparateBlobs = false>
struct llama::mapping::Split< TArrayExtents, TRecordDim, TSelectorForMapping1, MappingTemplate1, MappingTemplate2, SeparateBlobs >

Mapping which splits off a part of the record dimension and maps it differently then the rest.

Template Parameters
TSelectorForMapping1Selects a part of the record dimension to be mapped by MappingTemplate1. Can be a RecordCoord, a type list of RecordCoords, a type list of tags (selecting one field), or a type list of type list of tags (selecting one field per sub list). dimension to be mapped differently.
MappingTemplate1The mapping used for the selected part of the record dimension.
MappingTemplate2The mapping used for the not selected part of the record dimension.
SeparateBlobsIf true, both pieces of the record dimension are mapped to separate blobs.
