Method Summary

void	afterInitialize() invoked to ensure that thre RDBMS instance is already created within Sail
void	createDependenciesTable() need to handle creation of DEPEND table because some of the rules may need more than 2 columns to store the dependency (rules with three or more triple templates in CustomInferencer) An example of such rule: a rdf:type owl:TransitiveProperty x a b b a c infer: x a c so the (x a c) triple is dependant from all those
void	doInferencing() the entry point for statement inferencing
void	initialize(RdfSchemaRepository sail, Map configParams) invoked within sail.initialize(Map configParam).
void	initRdfSchema() invoked to initialize the basic RDFS schema for the repository
void	markAxioms() invoked to mark the currently added statements as axioms
void	processNewStatements() invoked when some staements are being added so to infer the dependancy information for them
void	removeExpiredStatements() invoked when some statements are being removed
void	setDependencyInferencer(boolean useDependencyInferencer)

Method Detail

initialize

public void initialize(RdfSchemaRepository sail,
                       Map configParams)

invoked within sail.initialize(Map configParam). Allows to initialize the custom inferencer(s) with params provided in system.conf

Parameters:

sail - - to which the inferencer is embedded

configParams - - a map holding the sail's confic parameters

initRdfSchema

public void initRdfSchema()

invoked to initialize the basic RDFS schema for the repository

doInferencing

public void doInferencing()

the entry point for statement inferencing

setDependencyInferencer

public void setDependencyInferencer(boolean useDependencyInferencer)

removeExpiredStatements

public void removeExpiredStatements()
                             throws SQLException

invoked when some statements are being removed

Throws:

SQLException

processNewStatements

public void processNewStatements()
                          throws SQLException

invoked when some staements are being added so to infer the dependancy information for them

Throws:

SQLException

markAxioms

public void markAxioms()
                throws SQLException

invoked to mark the currently added statements as axioms

Throws:

SQLException

createDependenciesTable

public void createDependenciesTable()
                             throws SQLException

need to handle creation of DEPEND table because some of the rules may need more than 2 columns to store the dependency (rules with three or more triple templates in CustomInferencer) An example of such rule: a rdf:type owl:TransitiveProperty x a b b a c infer: x a c so the (x a c) triple is dependant from all those

Throws:

SQLException

afterInitialize

public void afterInitialize()

invoked to ensure that thre RDBMS instance is already created within Sail
