public interface Connector
extends Builtin

Interface for connector built-in.
A connector built-in allows for more than one input value
and creates one or more result values.
Usually connectors are used to fetch values from an external
data source like a database.

Method Details

start

void start(BitSet grounds,
 BuiltinReceiver receiver)
    throws ReasoningException,
InterruptedException,
IOException

Start feeding the built-in with input values. Grounds indicates the ground arguments;
receiver catches the results of the evaluation

Parameters:

grounds - , the arguments which are ground

receiver - , the receiver receiving the results

Throws:

ReasoningException

InterruptedException

IOException

input

void input(long[] input)
    throws InterruptedException,
IOException,
SemReasonerException

Feed the built-in with an input tuple.
The built-in may produce at any time results,
may be during feeding or may be after calling stop

Parameters:

input - encoded input tuple

Throws:

InterruptedException

IOException

SemReasonerException

stop

void stop()
   throws InterruptedException,
IOException,
SemReasonerException

stop feeding the built-in with input values

Throws:

InterruptedException

IOException

SemReasonerException
