org.topbraid.spin.arq.SPINFunctionDrivers

All Implemented Interfaces:

SPINFunctionDriver

public class SPINFunctionDrivers
extends Object
implements SPINFunctionDriver

The singleton that creates ARQ FunctionFactories from SPIN and SHACL functions. Can be used by applications to install a different singleton with support for different kinds of functions, such as SPINx.

Method Detail

get

public static SPINFunctionDrivers get()

set

public static void set(SPINFunctionDrivers value)

create

public SPINFunctionFactory create(org.apache.jena.rdf.model.Resource function)

Description copied from interface: SPINFunctionDriver

If this factory is responsible for the provided function Resource then it must create a FunctionFactory which can then be registered.

Specified by:

create in interface SPINFunctionDriver

Parameters:

function - the SPIN Function's resource

Returns:

the FunctionFactory or null if this is not responsible

register

public void register(org.apache.jena.rdf.model.Property predicate,
                     SPINFunctionDriver driver)

Registers a new SPINFunctionDriver for a given key predicate. For example, SPARQLMotion functions are recognized via sm:body. Any previous entry will be overwritten.

Parameters:

predicate - the key predicate

driver - the driver to register
