    - #### contains

          public boolean contains(Resource subj,
                                  IRI pred,
                                  Value obj,
                                  Resource... contexts)

      Deprecated.
      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` .

      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)

      Deprecated.
      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.
      Parameters:
        `subj` - The statement's subject.
        `pred` - The statement's predicate.
        `obj` - The statement's object.
        `contexts` - The contexts to add statements to.

    - #### remove

          public boolean remove(Resource subj,
                                IRI pred,
                                Value obj,
                                Resource... contexts)

      Deprecated.
      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`.

      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.

    - #### clear

          public boolean clear(Resource... contexts)

      Deprecated.
      Description copied from interface: `Model`
      Removes statements with the specified context exist in this model.
      Specified by:
        `clear` in interface `Model`
      Overrides:
        `clear` in class `AbstractModel`
      Parameters:
        `contexts` - The context of the statements to remove.
      Returns:
        `true` if one or more statements have been removed.

    - #### filter

          public Model filter(Resource subj,
                              IRI pred,
                              Value obj,
                              Resource... contexts)

      Deprecated.
      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`.

      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.
