Constructor Detail

AbstractGetFeatureInfoRequest

public AbstractGetFeatureInfoRequest(java.net.URL onlineResource,
                                     GetMapRequest request)

Constructs a GetFeatureInfoRequest. It will set the REQUEST and VERSION parameters, over-writing and values set there previously.

Parameters:

onlineResource - the URL pointing to the place to execute a GetFeatureInfo request

request - a previously configured GetMapRequest that the query will be executed on

Method Detail

getFinalURL

public java.net.URL getFinalURL()

Description copied from interface: Request

Once the properties of the request are configured, this will return the URL that points to the server and contains all of the appropriate name/value parameters.

Specified by:

getFinalURL in interface Request

Overrides:

getFinalURL in class AbstractRequest

See Also:

addQueryLayer

public void addQueryLayer(Layer layer)

Description copied from interface: GetFeatureInfoRequest

Add a Layer to the set of layers to be queried in the request. This Layer must have queryable set to true.

Specified by:

addQueryLayer in interface GetFeatureInfoRequest

Parameters:

layer - a queryable Layer

See Also:

GetFeatureInfoRequest.addQueryLayer(org.geotools.data.ows.Layer)

setQueryLayers

public void setQueryLayers(java.util.Set layers)

Description copied from interface: GetFeatureInfoRequest

An unordered set of type Layer. These are the layers that the GetFeatureInfo request will be performed on.

Specified by:

setQueryLayers in interface GetFeatureInfoRequest

Parameters:

layers - A Set of type Layer, each to be queried

See Also:

GetFeatureInfoRequest.setQueryLayers(java.util.Set)

setInfoFormat

public void setInfoFormat(java.lang.String infoFormat)

Description copied from interface: GetFeatureInfoRequest

Sets the INFO_FORMAT parameter, which specifies the format of the GetFeatureInfoResponse. Valid values are available in getInfoFormats()

Specified by:

setInfoFormat in interface GetFeatureInfoRequest

Parameters:

infoFormat - a value from getInfoFormats()

See Also:

setFeatureCount

public void setFeatureCount(java.lang.String featureCount)

Specified by:

setFeatureCount in interface GetFeatureInfoRequest

Parameters:

featureCount - the maximum number of features to return in the response

See Also:

GetFeatureInfoRequest.setFeatureCount(java.lang.String)

setFeatureCount

public void setFeatureCount(int featureCount)

Specified by:

setFeatureCount in interface GetFeatureInfoRequest

Parameters:

featureCount - the maximum number of features to return in the response

See Also:

GetFeatureInfoRequest.setFeatureCount(int)

setQueryPoint

public void setQueryPoint(int x,
                          int y)

Description copied from interface: GetFeatureInfoRequest

The point on the image (in pixels) to be queried. The image is represented by the GetMapRequest passed into the constructor.

Specified by:

setQueryPoint in interface GetFeatureInfoRequest

Parameters:

x - the x point, in pixels

y - the y point, in pixels

See Also:

GetFeatureInfoRequest.setQueryPoint(int, int)

getQueryX

protected java.lang.String getQueryX()

Created because the 1.3.0 spec changes this parameter name. The 1.3.0 spec should over-ride this method.

Returns:

a String representing the x-axis query point

getQueryY

protected java.lang.String getQueryY()

Created because the 1.3.0 spec changes this parameter name. The 1.3.0 spec should over-ride this method.

Returns:

a String representing the y-axis query point

initRequest

protected void initRequest()

initVersion

protected abstract void initVersion()
