Interface ModelSetAddRemove

All Superinterfaces:

ClosableIterable<Statement>, java.lang.Iterable<Statement>, Lockable

All Known Subinterfaces:

ModelSet

public interface ModelSetAddRemove
extends ClosableIterable<Statement>, Lockable

Allows to add and removes statements from a ModelSet. Statements without a context are added/removed from the default model. For plain triples models, this is modeled as a number of interfaces: ClosableIterable, ModelWriter, Lockable

Method Summary

void	addAll(java.util.Iterator<? extends Statement> statement) For each statement in the iterator, this method creates a Model named statement.getContextURI if needed.
void	addStatement(Statement statement) This method creates a Model named statement.getContextURI if needed.
void	addStatement(URI contextURI, Resource subject, URI predicate, Node object) This method creates a Model named 'contextURI' if needed.
void	removeAll(java.util.Iterator<? extends Statement> statement) For each statement in the iterator, the statement is removed form the model named statement.getContext(); If the model named statement.getContext() becomes empty, it remains in the ModelSet.
void	removeStatement(Statement statement) Removes the statement (s,p,o) from a model named statement.getContext().
void	removeStatement(URI contextURI, Resource subject, URI predicate, Node object) Removes the statement (s,p,o) from a model named contextURI.
void	removeStatements(QuadPattern quadPattern) Find all models matching the context of the pattern and remove all matching triple patterms from them
void	removeStatements(UriOrVariable context, ResourceOrVariable subject, UriOrVariable predicate, NodeOrVariable object) Find all models matching the context, and remove all (subject, property ,object)-statements from these model
void	update(DiffReader diff) Apply the changes given by this diff in one atomic operation Implementations must check that all statements to be removed are still in the Model.

Method Detail

addStatement

void addStatement(URI contextURI,
                  Resource subject,
                  URI predicate,
                  Node object)
                  throws ModelRuntimeException

This method creates a Model named 'contextURI' if needed. Then the statement (s,p,o) is inserted into that model.

Parameters:

contextURI - a URI or null

subject - a Resource (URI or BlankNode)

predicate -

object - a Node

Throws:

ModelRuntimeException - if any internal (I/O related) exception occurs

addStatement

void addStatement(Statement statement)
                  throws ModelRuntimeException

This method creates a Model named statement.getContextURI if needed. Then the statement (s,p,o) is inserted into that model.

Parameters:

statement -

Throws:

ModelRuntimeException - if any internal (I/O related) exception occurs

addAll

void addAll(java.util.Iterator<? extends Statement> statement)
            throws ModelRuntimeException

For each statement in the iterator, this method creates a Model named statement.getContextURI if needed. Then the statement (s,p,o) is inserted into that model.

Parameters:

statement -

Throws:

ModelRuntimeException - if any internal (I/O related) exception occurs

removeStatement

void removeStatement(URI contextURI,
                     Resource subject,
                     URI predicate,
                     Node object)
                     throws ModelRuntimeException

Removes the statement (s,p,o) from a model named contextURI. If the model named 'contextURI' becomes empty, it remains in the ModelSet.

Parameters:

context - a URI or null

subject - a Resource (URI or BlankNode)

predicate -

object - a Node

Throws:

ModelRuntimeException - if any internal (I/O related) exception occurs

removeStatement

void removeStatement(Statement statement)
                     throws ModelRuntimeException

Removes the statement (s,p,o) from a model named statement.getContext(). If the model named statement.getContext() becomes empty, it remains in the ModelSet.

Parameters:

statement - a Statement

Throws:

ModelRuntimeException - if any internal (I/O related) exception occurs

removeAll

void removeAll(java.util.Iterator<? extends Statement> statement)
               throws ModelRuntimeException

For each statement in the iterator, the statement is removed form the model named statement.getContext(); If the model named statement.getContext() becomes empty, it remains in the ModelSet.

Parameters:

statement -

Throws:

ModelRuntimeException - if any internal (I/O related) exception occurs

removeStatements

void removeStatements(QuadPattern quadPattern)
                      throws ModelRuntimeException

Find all models matching the context of the pattern and remove all matching triple patterms from them

Parameters:

quadPattern -

Throws:

ModelRuntimeException

removeStatements

void removeStatements(UriOrVariable context,
                      ResourceOrVariable subject,
                      UriOrVariable predicate,
                      NodeOrVariable object)
                      throws ModelRuntimeException

Find all models matching the context, and remove all (subject, property ,object)-statements from these model

Throws:

ModelRuntimeException

update

void update(DiffReader diff)
            throws ModelRuntimeException

Apply the changes given by this diff in one atomic operation Implementations must check that all statements to be removed are still in the Model. Otherwise an exception is thrown. First all triples to be removed are removed, then triples to be added are added. In this modelset, this means (s,p,o) is removed from the graph named c, for all statements (c,s,p,o). Note: Models becoming empty are not removed.

Parameters:

diff -

Throws:

ModelRuntimeException - if a model or statement in a model to be removed does not exist.
