Method Details

standardRegistry

public static IteratorFunctionRegistry standardRegistry()

get

public static IteratorFunctionRegistry get()

get

public static IteratorFunctionRegistry get(org.apache.jena.sparql.util.Context context)

set

public static void set(org.apache.jena.sparql.util.Context context,
 IteratorFunctionRegistry reg)

put

public void put(String uri,
 Class<?> funcClass)

Insert a class that is the iterator function implementation

Parameters:

uri - String URI

funcClass - Class for the function (new instance called).

put

public void put(String uri,
 IteratorFunctionFactory f)

Insert a iterator. Re-inserting with the same URI overwrites the old entry.

Parameters:

uri -

f -

isRegistered

public boolean isRegistered(String uri)

keys

public Iterator<String> keys()

Iterate over URIs

remove

public IteratorFunctionFactory remove(String uri)

Remove by URI

Parameters:

uri -

Returns:

get

public IteratorFunctionFactory get(String uri)

Lookup by URI

Returns:

the iterator, or null
