All Implemented Interfaces:

DeclarativeFunctionDriver

public class DeclarativeFunctionDrivers
extends Object
implements DeclarativeFunctionDriver

The singleton that creates ARQ FunctionFactories from (SHACL, SPIN) function declarations. Can be used by applications to install a different singleton with support for different kinds of functions, such as SHACL-JS or Script-based functions.

get

public static DeclarativeFunctionDrivers get()

set

public static void set(DeclarativeFunctionDrivers value)

create

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

Description copied from interface: DeclarativeFunctionDriver

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 DeclarativeFunctionDriver

Parameters:

function - the function's declaration resource

Returns:

the FunctionFactory or null if this is not responsible

register

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

Registers a new DeclarativeFunctionDriver 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
