Implements a query method that selection all data subsets of a distributed dataset covered by a region of interest.
The class Distributed_data_subset_locality_query_mode implements the base class IDistributed_data_subset_locality_query_mode. The purpose of the implementation is to conveniently determine all data subsets of a distributed dataset that are inside or intersect a given spatial area.

Instantiating a query method using the distributed dataset unique identifier and a given region of interest.
The spatial query is defined in continuous space which requires a bounding box defined using floating-point min and max values.
- Parameters
-
| [in] | tag | The mi::neuraylib::Tag_struct identifies the distributed dataset. |
| [in] | coverage | The bounding box specifies the region of interest for the locality query. |

Instantiating a query method using the distributed dataset unique identifier and a given region of interest.
The spatial query is defined in continuous space but the region of interest here is defined using integer min and max values. The bounding box is converted to a floating-point bounding box first.
- Parameters
-
| [in] | tag | The mi::neuraylib::Tag_struct identifies the distributed dataset. |
| [in] | coverage | The bounding box specifies the region of interest for the locality query. |

Implements the query method that applies to a distributed dataset that is referred to by an unique identifier.
- Returns
- Return the
mi::neuraylib::Tag_struct that uniquely identifies the entire distributed dataset.

Implements the spatial query method let determine data localities based on a spatial coverage.
The bounding box represented by mi::math::Bbox_struct<mi::Float32, 3> specify a spatial region of interest. All data subsets that are covered at least partially, will be considered in a data locality.
- Returns
- Returns the a bounding box that represents a region of interest for determining the data locality. An invalid bounding box will be ignored and the space that the entire distributed dataset covers will be considered instead.
