Method Detail

findStatements

ClosableIterator<Statement> findStatements(UriOrVariable contextURI,
                                           ResourceOrVariable subject,
                                           UriOrVariable predicate,
                                           NodeOrVariable object)
                                           throws ModelRuntimeException

Search across all existing models

Parameters:

contextURI -

subject -

predicate -

object -

Returns:

Throws:

ModelRuntimeException

findStatements

ClosableIterator<Statement> findStatements(QuadPattern pattern)
                                           throws ModelRuntimeException

Search across all existing models and retunrs all statements matching the quad pattern

Parameters:

pattern -

Returns:

Throws:

ModelRuntimeException

containsStatements

boolean containsStatements(UriOrVariable contextURI,
                           ResourceOrVariable subject,
                           UriOrVariable predicate,
                           NodeOrVariable object)
                           throws ModelRuntimeException

Parameters:

contextURI -

subject -

predicate -

object -

Returns:

true, if a Model named 'contextURI' contains the statement (s,p,o)

Throws:

ModelRuntimeException

contains

boolean contains(Statement s)
                 throws ModelRuntimeException

Parameters:

s - a Statement

Returns:

true if the modelset contains a model with context s.getContext() which contains the statement s. If the context is null, the default graph is checked.

Throws:

ModelRuntimeException

countStatements

long countStatements(QuadPattern pattern)
                     throws ModelRuntimeException

Parameters:

pattern -

Returns:

the number of statements matchingthe pattern. This is for all graphs matching the context of the pattern (this is none, one or all graphs). In matching graphs the number of matching statements is accumulated and returned.

Throws:

ModelRuntimeException

createQuadPattern

QuadPattern createQuadPattern(UriOrVariable context,
                              ResourceOrVariable subject,
                              UriOrVariable predicate,
                              NodeOrVariable object)

Parameters:

context -

subject -

predicate -

object -

Returns:

a QuadPattern
