create

create

public static QuadModel create(Iterable<org.openrdf.model.Statement> statements)

wrap

public static QuadModel wrap(org.openrdf.sail.SailConnection connection,
                             boolean trackChanges)

Returns a QuadModel view of the supplied SailConnection. Given to the use of internal locks in some SAIL implementations (e.g., the MemoryStore), the returned view should be used only inside a thread, similarly to the SailConnection it wraps. Parameter trackChanges enables or disables the checks performed each time a statement is added or removed that the model was changed.

Parameters:

connection - the connection to wrap

trackChanges - true, if addition/deletion operations should return true or false based on whether the model was actually changed by the operation; if false, the check is skipped and all modification operations return true

Returns:

the created QuadModel view

                              org.openrdf.model.Resource... ctxs)

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.

Parameters:

subj - the subject to match, or null to match any subject

pred - the predicate to match, or null to match any predicate

obj - the object to match, or null to match any object

ctxs - the contexts to match; if empty, any statement context will be matched

Returns:

true, if there are statements matching the specified pattern

subj - the subject

pred - the predicate

obj - the object.

ctxs - the contexts to add statements to.

Returns:

true if the model changed as a result of the operation

Throws:

IllegalArgumentException - if this quad model cannot store the given statement, because it is filtered out of this view.

UnsupportedOperationException - if this quad model cannot accept any statements, because it is filtered to the empty set.

clear

public final void clear()

Specified by:

clear in interface Collection<org.openrdf.model.Statement>

Overrides:

clear in class AbstractCollection<org.openrdf.model.Statement>

clear

public final boolean clear(org.openrdf.model.Resource... contexts)

Removes statements with the specified context existing in this quad model.

Parameters:

contexts - the contexts of the statements to remove

Returns:

true, if one or more statements have been removed.

remove

public final boolean remove(@Nullable
                            org.openrdf.model.Resource subj,
                            @Nullable
                            org.openrdf.model.URI pred,
                            @Nullable
                            org.openrdf.model.Value obj,
                            org.openrdf.model.Resource... ctxs)

Removes statements with the specified subject, predicate, object and (optionally) context existing 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 context is 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.

Parameters:

subj - the subject to match, or null to match any subject

pred - the predicate to match, or null to match any predicate

obj - the object to match, or null to match any object

ctxs - the contexts to match; if empty, any statement context will be matched

Returns:

true, if one or more statements have been removed.

removeAll

public boolean removeAll(Collection<?> c)

Specified by:

removeAll in interface Collection<org.openrdf.model.Statement>

Overrides:

removeAll in class AbstractCollection<org.openrdf.model.Statement>

filter

public QuadModel filter(@Nullable
                        org.openrdf.model.Resource subj,
                        @Nullable
                        org.openrdf.model.URI pred,
                        @Nullable
                        org.openrdf.model.Value obj,
                        org.openrdf.model.Resource... ctxs)

Returns a 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 context is 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 quad model is backed by this model, so changes to this model are reflected in the returned model, and vice-versa. If this quad 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 returned quad model supports element removal, which removes the corresponding statement from this model. Statements can be added to the returned quad model only if they match the filter pattern.

Parameters:

subj - the subject to match, or null to match any subject

pred - the predicate to match, or null to match any predicate

obj - the object to match, or null to match any object

ctxs - the contexts to match; if empty, any statement context will be matched

Returns:

a quad model view with the statements matching the pattern specified

filter

public QuadModel filter(Collection<org.openrdf.model.Statement> statements)

Returns an immutable view of a subset of this model, containing the specified statements. The supplied collection of statements must not contain duplicates and must be a subset of the statements in this model.

Parameters:

statements - the statements of this model to include in the returned immutable view, without duplicates

Returns:

an immutable view of this model including only the statements specified

subjects

public final Set<org.openrdf.model.Resource> subjects()

Returns a Set view of the subjects contained in this model. The set is backed by this model, so changes to this 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 the corresponding statement from the model. It does not support element addition, unless this quad model is a filtered quad model with non-null pred and obj filter parameteres.

Returns:

a set view of the subjects contained in this quad model

predicates

public final Set<org.openrdf.model.URI> predicates()

Returns a Set view of the predicates contained in this model. The set is backed by this model, so changes to this 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 the corresponding statement from the model. It does not support element addition, unless this is a filtered quad model with non-null subj and obj filter parameters.

Returns:

a set view of the predicates contained in this quad model

objects

public final Set<org.openrdf.model.Value> objects()

Returns a Set view of the objects contained in this model. The set is backed by this model, so changes to this 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 the corresponding statement from the model. It does not support element addition, unless this is a filtered quad model with non-null subj and pred filter parameters.

Returns:

a set view of the objects contained in this quad model

contexts

public final Set<org.openrdf.model.Resource> contexts()

Returns a Set view of the contexts contained in this model. The set is backed by this model, so changes to this 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 the corresponding statement from the model. It does not support element addition, unless this is a filtered quad model with non-null subj, pred and obj filter parameters.

Returns:

a set view of the contexts contained in this quad model

Gets the object of the statement(s). If the quad model contains one or more statements, all these statements should have the same object. A ModelException is thrown if this is not the case.

Returns:

the object of the statement(s) in this model, or null if this model is empty

Throws:

org.openrdf.model.util.ModelException - if multiple objects are present

@Nullable
public final org.openrdf.model.Resource objectResource()
                                                          throws org.openrdf.model.util.ModelException

Utility method that casts the return value of objectValue() to a Resource, or throws a ModelException if that value is not a Resource.

Returns:

the resource object of statement(s) in this model, or null if this model is empty
