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.

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
