Method Details

filter

public final UniDataStream<Solution_,A> filter(Predicate<A> predicate)

Description copied from interface: UniDataStream

Exhaustively test each fact against the Predicate and match if Predicate.test(Object) returns true.

Specified by:

filter in interface UniDataStream<Solution_,A>

ifExists

@SafeVarargs
public final <B> UniDataStream<Solution_,A> ifExists(Class<B> otherClass,
 BiJoiner<A,B>... joiners)

Description copied from interface: UniDataStream

Create a new UniDataStream for every A where B exists for which all BiJoiners are true (for the properties they extract from both facts).

Specified by:

ifExists in interface UniDataStream<Solution_,A>

Type Parameters:

B - the type of the second matched fact

Returns:

a stream that matches every A where B exists for which the BiJoiners are true

ifExists

@SafeVarargs
public final <B> UniDataStream<Solution_,A> ifExists(UniDataStream<Solution_,B> otherStream,
 BiJoiner<A,B>... joiners)

Description copied from interface: UniDataStream

Create a new UniDataStream for every A where B exists for which all BiJoiners are true (for the properties it extracts from both facts).

Specified by:

ifExists in interface UniDataStream<Solution_,A>

Type Parameters:

B - the type of the second matched fact

Returns:

a stream that matches every A where B exists for which the BiJoiners are true

ifNotExists

@SafeVarargs

 BiJoiner<A,B>... joiners)

Description copied from interface: UniDataStream

Create a new UniDataStream for every A where B does not exist for which the BiJoiners are true (for the properties they extract from both facts).

Specified by:

ifNotExists in interface UniDataStream<Solution_,A>

Type Parameters:

B - the type of the second matched fact

Returns:

a stream that matches every A where B does not exist for which the BiJoiners are true

ifNotExists

@SafeVarargs
public final <B> UniDataStream<Solution_,A> ifNotExists(UniDataStream<Solution_,B> otherStream,
 BiJoiner<A,B>... joiners)

Description copied from interface: UniDataStream

Create a new UniDataStream for every A where B does not exist for which the BiJoiners are true (for the properties they extract from both facts).

Specified by:

ifNotExists in interface UniDataStream<Solution_,A>

Type Parameters:

B - the type of the second matched fact

Returns:

a stream that matches every A where B does not exist for which the BiJoiners are true
