Examples of net.opengis.wfs.GetFeatureType

net.opengis.wfs.GetFeatureType
A representation of the model object 'Get Feature Type'. A GetFeature element contains one or more Query elements that describe a query operation on one feature type. In response to a GetFeature request, a Web Feature Service must be able to generate a GML3 response that validates using a schema generated by the DescribeFeatureType request. A Web Feature Service may support other possibly non-XML (and even binary) output formats as long as those formats are advertised in the capabilities document.
The following features are supported:
- {@link net.opengis.wfs.GetFeatureType#getQuery Query}
- {@link net.opengis.wfs.GetFeatureType#getMaxFeatures Max Features}
- {@link net.opengis.wfs.GetFeatureType#getOutputFormat Output Format}
- {@link net.opengis.wfs.GetFeatureType#getResultType Result Type}
- {@link net.opengis.wfs.GetFeatureType#getTraverseXlinkDepth Traverse Xlink Depth}
- {@link net.opengis.wfs.GetFeatureType#getTraverseXlinkExpiry Traverse Xlink Expiry}
- {@link net.opengis.wfs.GetFeatureType#getFormatOptions Format Options}
- {@link net.opengis.wfs.GetFeatureType#getMetadata Metadata}
- {@link net.opengis.wfs.GetFeatureType#getStartIndex Start Index}
- {@link net.opengis.wfs.GetFeatureType#getViewParams View Params}
