Method Detail

getScaleHint

public ScaleHint getScaleHint()

Returns:

the scale interval the data source is valid

getName

public QualifiedName getName()

Returns:

the name of the data source. The method may returns null if so no name is defined and a online resource or WFS filter have shall be returned.

getOGCWebService

public abstract OGCWebService getOGCWebService()
                                        throws OGCWebServiceException

Returns:

an instance of the OGCWebService that represents the datasource. Notice: if more than one layer uses data that are offered by the same OWS the deegree WMS shall just use one instance for accessing the OWS

Throws:

OGCWebServiceException

getType

public int getType()

Returns:

the type of the data source. possible values are:

• LOCALWFS
• LOCALWCS
• REMOTEWFS
• REMOTEWCS
• REMOTEWMS

the values are defined as constants in DataSource

isFailOnException

public boolean isFailOnException()

Returns:

true if the requesting of the complete layer and so of the complete request shall fail if access a datasource fails.

isQueryable

public boolean isQueryable()

Returns:

true i a datasource is queryable (considered for GetFeatureInfo requests)

getCapabilitiesURL

public URL getCapabilitiesURL()

Returns:

the URL of the capabilities document describing access to a datasource

getFeatureInfoTransform

public URL getFeatureInfoTransform()

Returns:

the URL of a XSLT script to transform the GML that internaly will be returned as result to a GetFeature or cascaded GetFeatureInfo request. The return is null if no transformation shall be performed.

getValidArea

public Geometry getValidArea()

Returns:

the area a datasource is valid

getRequestTimeLimit

public int getRequestTimeLimit()

Returns:

the maximum time in seconds a datasource shall be able to return a result.

toString

public String toString()

Overrides:
