Description copied from interface: Model

Add the RDF statements from a document. Uses content negotiation to request appropriate mime types. If the content type is not found, it may guess from the URL.

See Model for a description of how to traverse a firewall.

See "Reading and Writing RDF in Apache Jena" for more information about determining the syntax.

Specified by:

read in interface Model

Parameters:

url - of the document containing the RDF statements.

Returns:

this model

read

public Model read(Reader reader,
 String base)

Description copied from interface: Model

Using this method is often a mistake. Add statements from an RDF/XML serialization. It is generally better to use an InputStream if possible, otherwise there is a danger of a mismatch between the character encoding of say the FileReader and the character encoding of the data in the file. It is better to explicitly set the serialization format. See Model.read(InputStream, String, String) for explicitily setting the serialization language.

See "Reading and Writing RDF in Apache Jena" for more information about concrete syntaxes.

Specified by:

read in interface Model

base - the base uri to be used when converting relative URI's to absolute URI's and to guess the RDF serialization syntax.

Returns:

the current model

read

public Model read(InputStream reader,
 String base)

Description copied from interface: Model

Add statements from a document. This method assumes the concrete syntax is RDF/XML. See Model.read(InputStream, String, String) for explicitly setting the language.

See "Reading and Writing RDF in Apache Jena" for more information about concrete syntaxes.

Specified by:

read in interface Model

Parameters:

reader - the input stream

base - the base uri to be used when converting relative URI's to absolute URI's. (Resolving relative URIs and fragment IDs is done by prepending the base URI to the relative URI/fragment.) If there are no relative URIs in the source, this argument may safely be null. If the base is the empty string, then relative URIs will be retained in the model. This is typically unwise and will usually generate errors when writing the model back out.

Returns:

the current model

read

public Model read(String url,
 String lang)

Description copied from interface: Model

Add statements from a serializion in language lang to the model.
Predefined values for lang are "RDF/XML", "N-TRIPLE", "TURTLE" (or "TTL") and "N3". null represents the default language, "RDF/XML". "RDF/XML-ABBREV" is a synonym for "RDF/XML".

Specified by:

read in interface Model

Parameters:

url - a string representation of the url to read from

lang - the language of the serialization

Returns:

this model

read

public Model read(String url,
 String base,
 String lang)

Description copied from interface: Model

Read into this model the RDF at url, using baseURI as the base URI if it is non-null. The RDF is assumed to be RDF/XML unless lang is non-null, in which case it names the language to be used. Answer this model.

Specified by:

read in interface Model

read

public Model read(Reader reader,
 String base,
 String lang)

Description copied from interface: Model

Using this method is often a mistake. Add RDF statements represented in language lang to the model.
Predefined values for lang are "RDF/XML", "N-TRIPLE", "TURTLE" (or "TTL") and "N3". null represents the default language, "RDF/XML". "RDF/XML-ABBREV" is a synonym for "RDF/XML".
It is generally better to use an InputStream if possible. Model.read(InputStream,String), otherwise there is a danger of a mismatch between the character encoding of say the FileReader and the character encoding of the data in the file.

Specified by:

read in interface Model

Parameters:

reader - the source of the input serialization

base - the base uri to be used when converting relative URI's to absolute URI's. (Resolving relative URIs and fragment IDs is done by prepending the base URI to the relative URI/fragment.) If there are no relative URIs in the source, this argument may safely be null. If the base is the empty string, then relative URIs will be retained in the model. This is typically unwise and will usually generate errors when writing the model back out.

lang - the language of the serialization null selects the default

Returns:

this model

read

public Model read(InputStream reader,
 String base,
 String lang)

Description copied from interface: Model

Add RDF statements represented in language lang to the model.
Predefined values for lang are "RDF/XML", "N-TRIPLE", "TURTLE" (or "TTL"). null represents the default language, "RDF/XML". "RDF/XML-ABBREV" is a synonym for "RDF/XML".

Specified by:

read in interface Model

Parameters:

reader - the source of the input serialization

base - the base uri to be used when converting relative URI's to absolute URI's. (Resolving relative URIs and fragment IDs is done by prepending the base URI to the relative URI/fragment.) If there are no relative URIs in the source, this argument may safely be null. If the base is the empty string, then relative URIs will be retained in the model. This is typically unwise and will usually generate errors when writing the model back out.

listNameSpaces

public NsIterator listNameSpaces()

Description copied from interface: Model

(You probably don't want this method; more likely you want the PrefixMapping methods that Model supports.) List the namespaces used by predicates and types in the model. This method is really intended for use by the RDF/XML writer, which needs to know these namespaces to generate correct and vaguely pretty XML.

The namespaces returned are those of (a) every URI used as a property in the model and (b) those of every URI that appears as the object of an rdf:type statement.

Note that the notion of "namespace" used here is not that of an XML prefix-namespace, but just of the minimal legal left part of a URI (see Util.splitNamespace for details). If you want the RDF/XML (or N3) namespaces, treat the Model as a PrefixMapping.

Specified by:

listNameSpaces in interface Model

Returns:

an iterator over every predicate and type namespace

• PrefixMapping

samePrefixMappingAs

public boolean samePrefixMappingAs(PrefixMapping other)

setNsPrefix

public Model setNsPrefix(String prefix,
 String uri)

Description copied from interface: PrefixMapping

Specify the prefix name for a URI prefix string. Any existing use of that prefix name is overwritten. The result is this same prefixMapping. (The earlier restriction that adding second prefix for the same URI caused the earlier binding to be deleted has been withdrawn.)

A prefix name must be a valid NCName, or the empty string. The empty string is reserved to mean "the default namespace".

Need not check the RFC2396 validity of the URI. Bad URIs are either silently ignored or behave as if they were good. The earlier restriction that the URI should end with a non-NCName character has been removed.

Note, in particular, that the prefix mapping can only be used if it includes the URI up to any '#' character because '#' is not legal in the local part of an NCName.

Specified by:

setNsPrefix in interface Model

Specified by:

setNsPrefix in interface PrefixMapping

Parameters:

prefix - the string to be used for the prefix.

uri - the URI prefix to be named

Returns:

this PrefixMapping

removeNsPrefix

Specified by:

removeNsPrefix in interface Model

Specified by:

Parameters:

prefix - the prefix string to remove

Returns:

this PrefixMapping

Parameters:

prefixed - a QName or URI

Returns:

the expanded string if possible, otherwise the original string

qnameFor

If there are multiple applicable mappings available, the "most recent" is chosen if that is possible, otherwise one is picked "at random".

The result is primarily intended for human convenience: it is not necessarily a legal QName, as Tail need not be a legal NCName; and there's no way to tell a shortened name from a URI with an unusual scheme.

Specified by:

shortForm in interface PrefixMapping

Parameters:

uri - the URI string to try and prefix-compress

Returns:

the shortened form if possible, otherwise the unchanged argument

Description copied from interface: Model

Create a new, independent, model containing all the statements in this model together with all of those in another given model. By independent we mean that changes to the result model do not affect the operand models, and vice versa.

The new model need not be of the same type as either this model or the argument model: typically it will be a memory-based model, even if this model is a database model.

Specified by:

union in interface Model

Parameters:

model - The other model whose statements are to be included.

Returns:

A new model containing all the statements that are in either model

intersection

public Model intersection(Model other)

Intersect this with another model. As an attempt at optimisation, we try and ensure we iterate over the smaller model first. Nowadays it's not clear that this is a good idea, since size() can be expensive on database and inference models.

Specified by:

intersection in interface Model

Parameters:

other - The other model.

Returns:

A new model containing all the statements that are in both models.

• Model.intersection(org.apache.jena.rdf.model.Model)

intersect

public static Model intersect(Model smaller,
 Model larger)

Answer a Model that is the intersection of the two argument models. The first argument is the model iterated over, and the second argument is the one used to check for membership. [So the first one should be "small" and the second one "membership cheap".]

difference

public Model difference(Model model)

Description copied from interface: Model

Create a new, independent, model containing all the statements in this model which are not in another. The new model need not be of the same type as either this model or the argument model: typically it will be a memory-based model.

Specified by:

difference in interface Model

Parameters:

model - the other model whose statements are to be excluded.

Returns:

a new model containing all the statements in this model that are not in the given model.

toString

public String toString()

Overrides:

toString in class Object

reifiedToString

public String reifiedToString()

isIsomorphicWith

public boolean isIsomorphicWith(Model m)

Answer whether or not these two graphs are isomorphic.

Specified by:

isIsomorphicWith in interface Model

Parameters:

m - Compare against this.

Returns:

boolean True if the two RDF graphs are isomorphic.

getModelLock

public Lock getModelLock()

getLock

public Lock getLock()

Description copied from interface: Model

Get the model lock for this model.

See also the operations Lock.enterCriticalSection(boolean) and Lock.leaveCriticalSection().

It is better to use transactions.

Specified by:

getLock in interface Model

enterCriticalSection

public void enterCriticalSection(boolean requestReadLock)

Description copied from interface: Lock

Enter a critical section. The application must call leaveCriticialSection.

Specified by:

enterCriticalSection in interface Lock

Parameters:

requestReadLock - true implies a read lock, false implies write lock.

See Also:

• Lock.leaveCriticalSection()

leaveCriticalSection

public void leaveCriticalSection()

Description copied from interface: Lock

Leave a critical section. Releases the lock form the matching enterCriticalSection

Specified by:

leaveCriticalSection in interface Lock

See Also:

• Lock.enterCriticalSection(boolean)

register

public Model register(ModelChangedListener listener)

Register the listener with this model by registering its GraphListener adaption with the underlying Graph.

Specified by:

register in interface Model

Parameters:

listener - A ModelChangedListener to register for model events

Returns:

this model, for cascading

See Also:

• ModelChangedListener

unregister

public Model unregister(ModelChangedListener listener)

Unregister the listener from this model by unregistering its GraphListener adaption from the underlying Graph.

Specified by:

unregister in interface Model

Parameters:

listener - A ModelChangedListener to unregister from model events

Returns:

this model, for cascading

See Also:

• ModelChangedListener

adapt

public GraphListener adapt(ModelChangedListener L)

Answer a GraphListener that, when fed graph-level update events, fires the corresponding model-level event handlers in L.

Parameters:

L - a model listener to be wrapped as a graph listener

Returns:

a graph listener wrapping L

• ModelListenerAdapter

notifyEvent

public Model notifyEvent(Object e)

Description copied from interface: Model

Notify any listeners that the event e has occurred.

Specified by:

notifyEvent in interface Model

Parameters:

e - the event that has occurred
