Convenience method to register a function at Jena's default registry

register

public void register(String iri,
 Class<?> clazz,
 String methodName,
 Class<?>... paramTypes)

Convenience method that hides checked exceptions from Class.getMethod

registerAll

public void registerAll(boolean lazy,
 Class<?> clz)

Register all static methods with @Iri annotations

registerAll

public void registerAll(boolean lazy,
 Class<?> clz,
 Object invocationTarget)

Register all methods of the class with the given invocationTarget. If the invocation target is null then all static methods will be registered. Otherwise, if the invocation target is non-null then all non-static methods will be registered.

Parameters:

clz -

invocationTarget -

factory

public org.apache.jena.sparql.function.FunctionFactory factory(boolean lazy,
 Method method)

factory

public org.apache.jena.sparql.function.FunctionFactory factory(boolean lazy,
 Method method,
 Object invocationTarget)

getFunction

public static org.apache.jena.sparql.function.Function getFunction(Method method)

Lookup a function for a given method in the default registry. Uses getFunction(FunctionRegistry, Method).

getFunction

public static org.apache.jena.sparql.function.Function getFunction(org.apache.jena.sparql.function.FunctionRegistry registry,
 Method method)

Read a (static) method's @Iri annotation and use it to lookup a function in the given registry At present there is no direct mapping of methods to FuncionFactories (without having to read the @Iri annotation)
