vrs::DataLayoutStructArray< T, Size > Struct Template Reference

Helper class to include DataLayout structs containing a sliced array of DataPieceXXX and DataLayoutStruct while preserving the required uniqueness of the field names. Embedded DataPiece objects will have a name automatically prefixed with the name of the DataLayoutStruct, with a '/0'... /Size-1' in between. More...

Detailed Description

template<typename T, size_t Size>
struct vrs::DataLayoutStructArray< T, Size >

Helper class to include DataLayout structs containing a sliced array of DataPieceXXX and DataLayoutStruct while preserving the required uniqueness of the field names. Embedded DataPiece objects will have a name automatically prefixed with the name of the DataLayoutStruct, with a '/0'... /Size-1' in between.

DataLayoutStructArray can be nested within other DataLayoutStruct. If nesting arrays is not required consider using DataPieceArray instead of DataLayoutStructArray as it will be more efficient. Example:

struct PoseLayout : public DataLayoutStruct { DATA_LAYOUT_STRUCT(PoseLayout)

vrs::DataPieceVector<vrs::Matrix4Dd> orientation{"orientation"}; vrs::DataPieceVector<vrs::Matrix3Dd> translation{"translation"}; };

struct Tracking : public AutoDataLayout { DataLayoutStructArray<PoseLayout, 2> hands{"hands"};

vrs::AutoDataLayoutEnd endLayout; };

Tracking will declare:

• 2 vrs::DataPieceVector<vrs::Matrix4Dd> fields, labelled: "0/orientation" and "1/orientation"
• 2 vrs::DataPieceVector<vrs::Matrix3Dd> fields, labelled: "0/translation" and "1/translation"
