    returns

    an array of Identifiers for functions

    Exceptions thrown

    NoSuchNamespaceException If the namespace does not exist (optional).

  3. abstract def loadFunction(ident: Identifier): UnboundFunction

    Load a function by identifier from the catalog.

    Load a function by identifier from the catalog.

    ident

    a function identifier

    returns

    an unbound function instance

    Exceptions thrown

    NoSuchFunctionException If the function doesn't exist

  4. abstract def name(): String
