FeatureQuery dataclass

Bases: BaseInterface

Represents definitions of a query to obtain features from a list of layers. Be aware, that filters are not applied to the QslJobLayer in this implementation since passed filters can contain inter-layer-references.

Attributes:

  • layers (list[QslJobLayer]) –

    A list layers which should only reference vector sources and be queried.

  • aliases (list[str]) –

    An optional list of alias names. This has to be the same length as the list of datasets.

  • filter (OgcFilterFES20) –

    An optional filter which might reference all passed layers thats why layers has to be added

QslJobParameterFeature dataclass

Bases: QslJobParameter

As defined in WFS 2.0 specs, a request can be subdivided in a list of queries. This class is representing that.

Attributes:

  • queries (list[FeatureQuery]) –

    A list of queries which features should be extracted for.

  • start_index (int) –

    The offset for paging reason.

  • count (int | None) –

    The number of results to return.
