Docs For Class InfModel

Description

A InfModel Model extends a MemModel , by adding the ability to infer statements from known statements and RDFS/OWL-Schematas.

It uses the same interface as MemModel, thus making the infererence process hidden.

Methods

Constructor InfModel (line 78)

Constructor You can supply a base_uri

access: public

InfModel InfModel ([string $baseURI = NULL])

string $baseURI

add (line 172)

Adds a new triple to the Model without checking if the statement is already in the Model.

So if you want a duplicate free MemModel use the addWithoutDuplicates() function (which is slower then add()) If the statement's predicate label is supported by the inference, the matching rules are added.

throws: PhpError
access: public

void add (object Statement $statement)

object Statement $statement

Redefinition of:

MemModel::add(): Adds a new triple to the MemModel without checking if the statement is already in the MemModel.

Redefined in descendants as:

InfModelB::add() : Adds a new triple to the Model without checking, if the statement is already in the Model. So if you want a duplicate free Model use the addWithoutDuplicates() function (which is slower then add())
InfModelF::add() : Adds a new triple to the MemModel without checking if the statement is already in the MemModel.

findRegex (line 446)

Method to search for triples using Perl-style regular expressions.

NULL input for any parameter will match anything. Example: $result = $m->find_regex( NULL, NULL, $regex ); Finds all triples where the label of the object node matches the regular expression. Returns an empty MemModel if nothing is found.

This function is disabled in the Inference Model

access: public

object MemModel findRegex (string $subject_regex, string $predicate_regex, string $object_regex)

string $subject_regex
string $predicate_regex
string $object_regex

Redefinition of:

MemModel::findRegex(): Method to search for triples using Perl-style regular expressions.

findVocabulary (line 468)

Returns all tripels of a certain vocabulary.

$vocabulary is the namespace of the vocabulary inluding a # : / char at the end. e.g. http://www.w3.org/2000/01/rdf-schema# Returns an empty MemModel if nothing is found.

This function is disabled in the Inference Model.

access: public

object MemModel findVocabulary (string $vocabulary)

string $vocabulary

Redefinition of:

MemModel::findVocabulary(): Returns all tripels of a certain vocabulary.

getSchema (line 400)

Returns a model, containing all Statements, having a Predicate, that is supported by the inference.

access: public

object Model getSchema ()

replace (line 423)

General method to replace nodes of a MemModel.

This function is disabled in the Inference Model.

throws: PhpError
access: public

void replace (object Node $subject, object Node $predicate, object Node $object, object Node $replacement)

object Node $subject
object Node $predicate
object Node $object
object Node $replacement

Redefinition of:

MemModel::replace(): General method to replace nodes of a MemModel.
