public interface GetFeatureInfoRequest
extends Request

Information required for a GetFeatureInfo request.

Q: queryableLayers is a Set - is this true? Or is order important Q: infoFormats - what does this do? Do these match up with querableLayers? Or is it a list of formats our client is willing to understand?

Method Detail

setQueryLayers

void setQueryLayers(Set layers)

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

Parameters:

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

addQueryLayer

void addQueryLayer(Layer layer)

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

Parameters:

layer - a queryable Layer

setInfoFormat

void setInfoFormat(String infoFormat)

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

Parameters:

infoFormat - a value from getInfoFormats()

setFeatureCount

void setFeatureCount(String featureCount)

Parameters:

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

setFeatureCount

void setFeatureCount(int featureCount)

Parameters:

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

setQueryPoint

void setQueryPoint(int x,
                   int y)

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

Parameters:

x - the x point, in pixels

y - the y point, in pixels
