queryables abstract method

Future<OGCQueryableObject?> queryables()

Get optional metadata about queryable properties for the feature collection represented by this source.

Returns null if no "queryables" metadata is available for this feature source.

An instance of OGCQueryableObject contains metadata about supported queryable parameters (in properties) instantiated as OGCQueryableProperty objects. You may use this information when specifying actual query parameters (for feature collection properties) using BoundedItemsQuery class when calling items or itemsAll.

An OGC API Features service providing "queryables" metadata must publish support for the Queryables conformance class specified in the OGC API - Features - Part 3: Filtering standard.

Implementation

Future<OGCQueryableObject?> queryables();
