```
public abstract void register(Builtin impl)
```
    Register an implementation for a given builtin using its default name.
    
    Parameters:
    
    impl - the implementation of the builtin
  - register
```
public abstract void register(java.lang.String functor,
                              Builtin impl)
```
    Register an implementation for a given builtin functor.
    
    Parameters:
    
    functor - the name of the functor used to invoke the builtin
    
    impl - the implementation of the builtin
  - getImplementation
```
public abstract Builtin getImplementation(java.lang.String functor)
```
    Find the implementation of the given builtin functor.
    
    Parameters:
    
    functor - the name of the functor being invoked.
    
    Returns:
    
    a Builtin or null if there is none registered under that name
  - getImplementationByURI
```
public abstract Builtin getImplementationByURI(java.lang.String uri)
```
    Find the implementation of the given builtin functor.
    
    Parameters:
    
    uri - the URI of the builtin to be retrieved
    
    Returns:
    
    a Builtin or null if there is none registered under that name
