Interface org.ginf.Model

public interface Model
This is a programming interface to an RDF model. An RDF model is a directed labeled graph. This interface represents a model as set of triples. Every triple has a subject, a predicate and an object.

Method Index

o add(Resource, Resource, RDFnode)
Adds a new triple to the model.
o add(Resource, Resource, String)
Adds a new triple to the model.
o add(Triple)
Adds a new triple to the model.
o contains(Triple)
Tests if the model contains the given triple.
o create()
Creates empty model of the same Class
o difference(Model)
Set difference with another model.
o duplicate()
Clone the model.
o elements()
Enumerate triples
o find(Resource, Resource, RDFnode)
General method to search for triples.
o find1(Resource, Resource, RDFnode)
Search for a single triple.
o getURI()
Returns current base URI setting.
o remove(Triple)
Removes the triple from the model.
o setURI(String)
Set a base URI for the message.
o size()
Number of triples in the model
o union(Model)
Set union with another model.

Methods

o setURI 
 public abstract void setURI(String uri)
Set a base URI for the message. Affects creating of new resources and serialization syntax. null is just alright, meaning that the serializer will use always rdf:about and never rdf:ID

o getURI 
 public abstract String getURI()
Returns current base URI setting.

o size 
 public abstract int size()
Number of triples in the model

Returns:
number of triples
o elements 
 public abstract Enumeration elements()
Enumerate triples

o contains 
 public abstract boolean contains(Triple t)
Tests if the model contains the given triple.

Returns:
true if the triple belongs to the model; false otherwise.

o add 
 public abstract void add(Resource subject,
                          Resource predicate,
                          String object)
Adds a new triple to the model. A literal is created out of the string parameter object. This method is just a shortcut.

Resource
o add 
 public abstract void add(Resource subject,
                          Resource predicate,
                          RDFnode object)
Adds a new triple to the model. The object of the triple is an RDFnode.

Resource, RDFnode
o add 
 public abstract void add(Triple t)
Adds a new triple to the model.

See Also:
Triple
o remove 
 public abstract void remove(Triple t)
Removes the triple from the model.

Triple
o find 
 public abstract Model find(Resource subject,
                            Resource predicate,
                            RDFnode object)
General method to search for triples. null input for any parameter will match anything.

Example: Model result = m.find( null, RDF.type, new Resource("http://...#MyClass") )

finds all instances of the class MyClass

See Also:
Resource, RDFnode
o find1 
 public abstract Triple find1(Resource subject,
                              Resource predicate,
                              RDFnode object)
Search for a single triple. null input for any parameter will match anything.

Returns:
a single triple if such was found;
null if nothing was found;
otherwise a RuntimeException is thrown.
o duplicate 
 public abstract Model duplicate()
Clone the model.

o create 
 public abstract Model create()
Creates empty model of the same Class

o union 
 public abstract Model union(Model m)
Set union with another model.

Returns:
this, i.e. the model itself
o difference 
 public abstract Model difference(Model m)
Set difference with another model.

Returns:
this, i.e. the model itself
