Method Details

register

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(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(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
