Class GMLFeatureWriter

java.lang.Object
  org.deegree.gml.feature.GMLFeatureWriter

public class GMLFeatureWriter
extends Object

Stream-based writer for GML-encoded features and feature collections.

XLink handling

This implementation is aware of xlinks (local as well as remote) and allows to set the traverseXlinkDepth parameter, which controls the number of feature levels that are exported inline.

Constructor Detail

GMLFeatureWriter

public GMLFeatureWriter(XMLStreamWriter writer,
                        CRS outputCRS)

Parameters:

writer -

outputCRS - crs used for exported geometries, may be null (in that case, the crs of the geometries is used)

GMLFeatureWriter

public GMLFeatureWriter(GMLVersion version,
                        XMLStreamWriter writer,
                        CRS outputCRS,
                        CoordinateFormatter formatter,
                        String referenceTemplate,
                        PropertyName[] requestedProps,
                        int traverseXlinkDepth,
                        int traverseXlinkExpiry,
                        boolean exportSfGeometries)

Parameters:

version - GML version of the output, must not be null

writer -

outputCRS - crs used for exported geometries, may be null (in this case, the original crs of the geometries is used)

formatter - formatter to use for exporting coordinates, e.g. to limit the number of decimal places, may be null (use 5 decimal places)

referenceTemplate - URI template used to create references to local objects, e.g. http://localhost:8080/d3_wfs_lab/services?SERVICE=WFS&REQUEST=GetGmlObject&VERSION=1.1.0&TRAVERSEXLINKDEPTH=1&GMLOBJECTID={} , the substring {} is replaced by the object id

requestedProps - properties to be exported, may be null (export all properties)

traverseXlinkDepth -

traverseXlinkExpiry -

exportSfGeometries -
