Class WMSQueryLayers

java.lang.Object

com.atakmap.android.maps.tilesets.mobac.QueryLayers

com.atakmap.android.maps.tilesets.mobac.WMSQueryLayers

public class WMSQueryLayers
extends QueryLayers

Concrete class extending the QueryLayers abstract class, providing an implementation for querying a WMS server's GetCapabilities operation.

WMS layers may form a tree structure. Non-leaf nodes may be displayable as layers in their own right, or not. The layer metadata this class provides is returned in a recursive structure to represent that tree. The Layer.isDisplayable() method may be called to determine if a layer is a displayable layer, rather than just a "container" layer.

The WMS specification can be found here: http://cite.opengeospatial.org/teamengine/about/wms/1.1.1/site/ and http://cite.opengeospatial.org/teamengine/about/wms/1.3.0/site/

WMSQueryLayers

public WMSQueryLayers(java.lang.String baseURLStr)

Create a new WMSQueryLayers object with the given URL string that points to a WMS server. baseURLStr may be missing the protocol, in which case HTTP is assumed and "http://" will be pre-pended to the URL string.

No processing or network access is done at this time except for URL syntax validation; process() must be called to actually query the WMS.

Parameters:

baseURLStr - the URL of the WMS server.

Throws:

java.lang.IllegalArgumentException - if baseURLStr is not a valid URL, the above protocol exception notwithstanding.

WMSQueryLayers

public WMSQueryLayers(java.net.URL baseURL)

Create a new WMSQueryLayers object with the given URL that points to a WMS server.

No processing or network access is done at this time except for URL syntax validation; process() must be called to actually query the WMS.

Parameters:

baseURL - the URL of the WMS server.

Method Detail

process

public void process()
             throws java.io.IOException

Description copied from class: QueryLayers

Actually perform the query of the map server. An exception will be thrown in case of any failure. This function performs network access.

Specified by:

process in class QueryLayers

Throws:

java.io.IOException - in case of error.

constructAggregate

public static WebMapLayer constructAggregate(java.lang.String title,
                                             java.util.List<WebMapLayer> layers)

Responsible for producing an aggregate WebMapLayer Tested with: https://geoint.nrlssc.navy.mil/maritime/wms?REQUEST=GetCapabilities&VERSION=1.3.0&SERVICE=WMS

Parameters:

title - supplied title for the aggregrate.

layers - the layers to aggregate together.
