      • contains

        public boolean contains​(Resource subj,
                                IRI pred,
                                Value obj,
                                Resource... contexts)
        Description copied from interface: Model
        Determines if statements with the specified subject, predicate, object and (optionally) context exist in this model. The subject, predicate and object parameters can be null to indicate wildcards. The contexts parameter is a wildcard and accepts zero or more values. If no contexts are specified, statements will match disregarding their context. If one or more contexts are specified, statements with a context matching one of these will match. Note: to match statements without an associated context, specify the value null and explicitly cast it to type Resource.

        Examples: model.contains(s1, null, null) is true if any statements in this model have subject s1,
        model.contains(null, null, null, c1) is true if any statements in this model have context c1,
        model.contains(null, null, null, (Resource)null) is true if any statements in this model have no associated context,
        model.contains(null, null, null, c1, c2, c3) is true if any statements in this model have context c1, c2 or c3 .

        Specified by:
        contains in interface Model
        Parameters:
        subj - The subject of the statements to match, null to match statements with any subject.
        pred - The predicate of the statements to match, null to match statements with any predicate.
        obj - The object of the statements to match, null to match statements with any object.
        contexts - The contexts of the statements to match. If no contexts are specified, statements will match disregarding their context. If one or more contexts are specified, statements with a context matching one of these will match.
        Returns:
        true if statements match the specified pattern.
      • add

        public boolean add​(Resource subj,
                           IRI pred,
                           Value obj,
                           Resource... contexts)
        Description copied from interface: Model
        Adds one or more statements to the model. This method creates a statement for each specified context and adds those to the model. If no contexts are specified, a single statement with no associated context is added. If this Model is a filtered Model then null (if context empty) values are permitted and will use the corresponding filtered values.
        Specified by:
        add in interface Model
        Parameters:
        subj - The statement's subject.
        pred - The statement's predicate.
        obj - The statement's object.
        contexts - The contexts to add statements to.

        clear in interface Model
        Parameters:
        context - The context of the statements to remove.
        Returns:
        true if one or more statements have been removed.
      • remove

        public boolean remove​(Resource subj,
                              IRI pred,
                              Value obj,
                              Resource... contexts)
        Description copied from interface: Model
        Removes statements with the specified subject, predicate, object and (optionally) context exist in this model. The subject, predicate and object parameters can be null to indicate wildcards. The contexts parameter is a wildcard and accepts zero or more values. If no contexts are specified, statements will be removed disregarding their context. If one or more contexts are specified, statements with a context matching one of these will be removed. Note: to remove statements without an associated context, specify the value null and explicitly cast it to type Resource.

        Examples: model.remove(s1, null, null) removes any statements in this model have subject s1,
        model.remove(null, null, null, c1) removes any statements in this model have context c1 ,
        model.remove(null, null, null, (Resource)null) removes any statements in this model have no associated context,
        model.remove(null, null, null, c1, c2, c3) removes any statements in this model have context c1, c2 or c3.

        Specified by:
        remove in interface Model
        Parameters:
        subj - The subject of the statements to remove, null to remove statements with any subject.
        pred - The predicate of the statements to remove, null to remove statements with any predicate.
        obj - The object of the statements to remove, null to remove statements with any object.
        contexts - The contexts of the statements to remove. If no contexts are specified, statements will be removed disregarding their context. If one or more contexts are specified, statements with a context matching one of these will be removed.
        Returns:
        true if one or more statements have been removed.
      • filter

        public Model filter​(Resource subj,
                            IRI pred,
                            Value obj,
                            Resource... contexts)
        Description copied from interface: Model
        Returns a filtered view of the statements with the specified subject, predicate, object and (optionally) context. The subject, predicate and object parameters can be null to indicate wildcards. The contexts parameter is a wildcard and accepts zero or more values. If no contexts are specified, statements will match disregarding their context. If one or more contexts are specified, statements with a context matching one of these will match. Note: to match statements without an associated context, specify the value null and explicitly cast it to type Resource.

        The returned model is backed by this Model, so changes to this Model are reflected in the returned model, and vice-versa. If this Model is modified while an iteration over the returned model is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The model supports element removal, which removes the corresponding statement from this Model, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. The statements passed to the add and addAll operations must match the parameter pattern.

        Examples: model.filter(s1, null, null) matches all statements that have subject s1,
        model.filter(null, null, null, c1) matches all statements that have context c1,
        model.filter(null, null, null, (Resource)null) matches all statements that have no associated context,
        model.filter(null, null, null, c1, c2, c3) matches all statements that have context c1, c2 or c3.

        Specified by:
        filter in interface Model
        Parameters:
        subj - The subject of the statements to match, null to match statements with any subject.
        pred - The predicate of the statements to match, null to match statements with any predicate.
        obj - The object of the statements to match, null to match statements with any object.
        contexts - The contexts of the statements to match. If no contexts are specified, statements will match disregarding their context. If one or more contexts are specified, statements with a context matching one of these will match.
        Returns:
        The statements that match the specified pattern.

      • subjects

        public java.util.Set<Resource> subjects()
        Description copied from interface: Model
        Returns a Set view of the subjects contained in this model. The set is backed by the model, so changes to the model are reflected in the set, and vice-versa. If the model is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes all statements from the model for which that element is a subject value, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations if the parameters pred or obj are null.
        Specified by:
        subjects in interface Model
        Returns:
        a set view of the subjects contained in this model
      • predicates

        public java.util.Set<IRI> predicates()
        Description copied from interface: Model
        Returns a Set view of the predicates contained in this model. The set is backed by the model, so changes to the model are reflected in the set, and vice-versa. If the model is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes all statements from the model for which that element is a predicate value, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations if the parameters subj or obj are null.

        Description copied from interface: Model
        Returns a Set view of the objects contained in this model. The set is backed by the model, so changes to the model are reflected in the set, and vice-versa. If the model is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes all statements from the model for which that element is an object value, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations if the parameters subj or pred are null.
