isKnownFeatureType

public boolean isKnownFeatureType(java.lang.String featureType)

returns true if the submitted feature type is known by the data store

describeFeatureType

public void describeFeatureType(WFSDescribeFeatureTypeRequest request)

returns the describtion of one or more feature types

Parameters:

request - conainting the list of feature types that should be described

getFeature

public void getFeature(WFSGetFeatureRequest request)

returns the features that matches the submitted request

Parameters:

request - containing the request for zero, one or more features. The request, may contains a filter that describes the request more detailed

getFeatureWithLock

public void getFeatureWithLock(WFSGetFeatureWithLockRequest request)

Parameters:

request - containing the request for zero, one or more features. The request, may contains a filter that describes the request more detailed
