InputStream in, java. InfModel An extension to the normal Model interface that supports access to any underlying inference capability. String name, boolean strict Create a new Model associated with the given name. String name Create a Model that does not already exist - equivalent to createModel name, false. String name, boolean strict Find an existing Model that this factory knows about under the given name. String name Equivalent to openModel name, false. String o add a statement to this model.
String o, boolean wellFormed add a statement to this model. String o, java. String l add a statement to this model. String l, boolean wellFormed add a statement to this model. Object o add a statement to this model. List statements add all the statements in the List to this Model, going through the bulk update interface which means turning them into triples in one form or another.
List statements Remove all the statements in the list from this model, using the bulk update interface. String base, java. String lang Add RDF statements represented in language lang to the model.

System Properties Firewalls and Proxies Some of the methods, e. This can be accomplished using the standard java method of setting system properties.
PrefixMapping PrefixMapping. Factory , PrefixMapping. IllegalPrefixException , PrefixMapping. Add all the statements in another model to this model, including the reified statements. Determine whether this model contains any statements with a given subject and property. Determine if an S, P, O pattern is present in this model, with null allowed to represent a wildcard match. Determine if all of the statements in a model are also contained in this model. Determine if all of the statements returned by an iterator are contained in this model.
Determine if any of the statements in a model are also contained in this model. Determine if any of the statements returned by an iterator are contained in this model.
Create a property with a given URI composed from a namespace part and a localname part by concatenating the strings. Build a typed literal label from its value form using whatever datatype is currently registered as the the default representation for this java class.
Create a new, independant, model containing all the statements in this model which are not in another. Test whether the given object m is a model that is equal to this model, which is true iff the underlying graphs are identical Java objects. Find or create a ReifiedStatement corresponding to a Statement. Create a new, independant, model containing all the statements which are in both this model and another.
Answer true iff the model contains no explicit statements ie it's size is zero, listStatements would deliver the empty iterator.
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. Answer an iterator [with no duplicates] over all the resources in this model that have property p. Answer an iterator [with no duplicates] over all the resources in this model that have property p with value o. An alias for listResourcesWithProperty Property , retained for backward compatibility. An alias for listResourcesWithProperty , retained for backward compatibility.
Remove all the statements in the list from this model, using the bulk update interface. Remove any existing maplet with the given prefix name and answer this mapping. Create a new, independant, model containing all the statements in this model together with all of those in another given model. Update this PrefixMapping with the bindings in map , only adding those p, u pairs for which neither p nor u appears in this mapping.
Method Detail size long size size will return the number of statements in a concrete model, for a virtualized model such as one created by an inference engine, it will return an estimated lower bound for the numberof statements in the model but it is possible for a subsequent listStatements on such a model to discover more statements than size indicated. List all resources which are subjects of statements. Subsequent operations on those resource may modify this model.
Return a Resource instance with the given URI in this model. Return a Property instance with the given URI in this model. Create a new anonymous resource whose model is this model. Create a blank node resource with a specified identifier. Operations on the result may modify this model. Create a new resource associated with this model.
Create a literal from a String value. Build a typed literal from its lexical form. Build a typed literal from its value form. No language tag is supplied.
Create a Statement instance. Creating a statement does not add it to the set of statements in the model; see Model::add. This method may return an existing Statement with the correct components and model, or it may construct a fresh one, as it sees fit. Answer a new empty list. Answer a new list containing the resources from the given iterator, in order.
Add the RDF statements from a document. Add statements from a document. See read InputStream, String, String for explicitly setting the language. Add RDF statements represented in language lang to the model. Using this method is often a mistake. 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. Then we are using a file output stream to read data from the input stream and write to the file. Then use the file output stream to write it to file. You can use any of these methods to download the file from URL in java program. If you are looking for performance, then do some analysis by using both methods and see what suits your need. Thanks Pankaj for a very good example, explained is few simple steps. However, since I am a beginner in the field, I still cant apply the example to real exercise, I am trying to solve.
Please, I need your assistance as soon as you can. Have tried with other few examples but cant just complete it. Hello sir, Actually I want to download. I went through this code with different URL but it throws the following exception could you please help me out with this problem. The server might be blocking it, can you try after setting the User-Agent header? That way, it will look like the request is coming from a browser.
