AbstractParser

public AbstractParser()

Creates a Parser for dealing with WMS XML.

Method Detail

parseCapabilities

public Capabilities parseCapabilities(WMService service,
                                      InputStream inStream)
                               throws IOException

Parses the WMT_MS_Capabilities XML from the given InputStream into a Capabilities object.

Specified by:

parseCapabilities in interface IParser

Parameters:

service - the WMService from which this MapDescriptor is derived

inStream - the inputStream containing the WMT_MS_Capabilities XML to parse

Returns:

the MapDescriptor object created from the specified XML InputStream

Throws:

IOException

getRootPath

protected abstract String getRootPath()

checkCapabilities

protected void checkCapabilities(Document doc)
                          throws IOException

Throws:

IOException

parseCapabilities

protected abstract Capabilities parseCapabilities(WMService service,
                                                  Document doc)
                                           throws IOException

Throws:

IOException

getTitlePath

protected String getTitlePath()

getTitle

protected String getTitle(Document doc)
                   throws IOException

Throws:

IOException

protected LinkedList<String> getFormatList(Document doc)
                                    throws IOException

Throws:

IOException

getInfoFormats

protected LinkedList<String> getInfoFormats(Document doc)

wmsLayerFromNode

public MapLayer wmsLayerFromNode(Node layerNode)

Traverses the DOM tree underneath the specified Node and generates a corresponding WMSLayer object tree. The returned WMSLayer will be set to have the specified parent.

Parameters:

layerNode - a DOM Node which is a XML element

Returns:

a WMSLayer with complete subLayer tree that corresponds to the DOM Node provided
