Method Detail

subsumes

public boolean subsumes(FeatureMap aFeatureMap)

Test if this featureMap includes all features from aFeatureMap However, if aFeatureMap contains a feature whose value is equal to gate.creole.ANNIEConstants.LOOKUP_CLASS_FEATURE_NAME (which is normally "class"), then GATE will attempt to match that feature using an ontology which it will try to retreive from a feature in both the feature map through which this method is called and in aFeatureMap. If these do not return identical ontologies, or if either feature map does not contain an ontology, then matching will fail, and this method will return false. In summary, this method will not work normally when aFeatureMap contains a feature with the name "class".

Specified by:

subsumes in interface FeatureMap

Parameters:

aFeatureMap - object which will be included or not in this FeatureMap obj.If this param is null then it will return true.

Returns:

true if aFeatureMap is incuded in this obj. and false if not.

subsumes

public boolean subsumes(Ontology ontologyLR,
                        FeatureMap aFeatureMap)

Tests if this featureMap object includes aFeatureMap features.
If the feature map contains class and (optionally) ontology features:
then the ontologyLR is used to provide ontology based subsume with respect to the subClassOf relations.

Specified by:

subsumes in interface FeatureMap

Parameters:

ontologyLR - an ontology to be used for the subsume

aFeatureMap - object which will be included or not in this FeatureMap obj.

Returns:

true if this includes aFeatureMap and false if not.

getClassForURIOrName

protected OClass getClassForURIOrName(Ontology ontologyLR,
                                      String name)

Look up the given name in the given ontology. First we try treating the name as a complete URI and attempt to find the matching OClass. If this fails (either the name is not a URI or there is no class by that URI) then we try again, treating the name as local to the default namespace of the ontology.

Parameters:

ontologyLR - the ontology

name - the URI or local resource name to look up

Returns:

the corresponding OClass, or null if no suitable class could be found.

subsumes

public boolean subsumes(FeatureMap aFeatureMap,
                        Set<? extends Object> aFeatureNamesSet)

Tests if this featureMap object includes aFeatureMap but only for the those features present in the aFeatureNamesSet. However, if aFeatureMap contains a feature whose value is equal to gate.creole.ANNIEConstants.LOOKUP_CLASS_FEATURE_NAME (which is normally "class"), then GATE will attempt to match that feature using an ontology which it will try to retreive from a feature in both the feature map through which this method is called and in aFeatureMap. If these do not return identical ontologies, or if either feature map does not contain an ontology, then matching will fail, and this method will return false. In summary, this method will not work normally when aFeatureMap contains a feature with the name "class" if that feature is also in aFeatureNamesSet.

Specified by:

subsumes in interface FeatureMap

Parameters:

aFeatureMap - which will be included or not in this FeatureMap obj.If this param is null then it will return true.

aFeatureNamesSet - is a set of strings representing the names of the features that would be considered for subsumes. If aFeatureNamesSet is null then subsumes(FeatureMap) will be called.

Returns:

true if all features present in the aFeaturesNameSet from aFeatureMap are included in this obj, or false otherwise.

put

public Object put(Object key,
                  Object value)
