                          throws InterpreterException

Description copied from interface: Dispatcher

Invokes a function based on given parameters.

Specified by:

dispatch in interface Dispatcher

Parameters:

metadata - Metadata used for error reporting.

exprId - Expression identifier which can be used together with metadata to get information about the dispatch target for error reporting.

functionName - the logical name of the function being invoked.

overloadIds - A list of function overload ids. The dispatcher selects the unique overload from this list with matching arguments.

args - The arguments to pass to the function.

Returns:

The result of the function call.

Throws:

InterpreterException - if something goes wrong.

immutableCopy

public Dispatcher.ImmutableCopy immutableCopy()

Description copied from interface: Dispatcher

Returns an Dispatcher.ImmutableCopy from current instance.

Specified by:

immutableCopy in interface Dispatcher
