Public Methods

Method	Description
Dispose ( ) : void	This method closes the XmlReader member and the used HttpClientUtil instance.

Protected Methods

Method	Description
CreateFeature ( Geometry geom, string labelField, string labelValue ) : IFeature	This method adds a label to the collection.
GeometryFactory ( HttpClientUtil httpClientUtil, WfsFeatureTypeInfo featureTypeInfo ) : System	Protected constructor for the abstract class.
GeometryFactory ( XmlReader xmlReader, WfsFeatureTypeInfo featureTypeInfo ) : System	Protected constructor for the abstract class.
GetSubReaderOf ( XmlReader reader, string labelValue ) : XmlReader	This method retrieves an XmlReader within a specified context.
GetSubReaderOf ( XmlReader reader, string labelValue, List pathNodes ) : XmlReader	This method retrieves an XmlReader within a specified context. Moreover it collects label values before or after a geometry could be found.
ParseCoordinates ( XmlReader reader ) : Collection	This method parses a coordinates or posList(from 'GetFeature' response).

Private Methods

Method	Description
CreateGeometries ( Features features ) : Collection	Abstract method - overwritten by derived classes for producing instances derived from Mapsui.Geometries.Geometry.
CreateReader ( HttpClientUtil httpClientUtil ) : void	This method initializes the XmlReader member.
InitializePathNodes ( ) : void	This method initializes path nodes needed by the derived classes.
InitializeSeparators ( ) : void	This method initializes separator variables for parsing coordinates. From GML specification: Coordinates can be included in a single string, but there is no facility for validating string content. The value of the 'cs' attribute is the separator for coordinate values, and the value of the 'ts' attribute gives the tuple separator (a single space by default); the default values may be changed to reflect local usage.

Method Details

CreateFeature() protected method

This method adds a label to the collection.

GetSubReaderOf() protected method

This method retrieves an XmlReader within a specified context.

protected GetSubReaderOf ( XmlReader reader, string labelValue ) : XmlReader
reader	System.Xml.XmlReader	An XmlReader instance that is the origin of a created sub-reader
labelValue	string	A string array for recording a found label value. Pass 'null' to ignore searching for label values
return	System.Xml.XmlReader

GetSubReaderOf() protected method

This method retrieves an XmlReader within a specified context. Moreover it collects label values before or after a geometry could be found.

protected GetSubReaderOf ( XmlReader reader, string labelValue, List pathNodes ) : XmlReader
reader	System.Xml.XmlReader	An XmlReader instance that is the origin of a created sub-reader
labelValue	string	A string array for recording a found label value. Pass 'null' to ignore searching for label values
pathNodes	List	A list of instances defining the context of the retrieved reader
return	System.Xml.XmlReader

ParseCoordinates() protected method

This method parses a coordinates or posList(from 'GetFeature' response).

protected ParseCoordinates ( XmlReader reader ) : Collection
reader	System.Xml.XmlReader	An XmlReader instance at the position of the coordinates to read
