Method Summary

Modifier and Type	Method	Description
UniDataStream<Solution_,A>	filter(Predicate<A> predicate)	Exhaustively test each fact against the Predicate and match if Predicate.test(Object) returns true.
<B> UniDataStream<Solution_,A>	ifExists(UniDataStream<Solution_,B> otherStream, BiJoiner<A,B>... joiners)	Create a new UniDataStream for every A where B exists for which all BiJoiners are true (for the properties it extracts from both facts).
<B> UniDataStream<Solution_,A>	ifExists(Class<B> otherClass, BiJoiner<A,B>... joiners)	Create a new UniDataStream for every A where B exists for which all BiJoiners are true (for the properties they extract from both facts).
default UniDataStream<Solution_,A>	ifExistsOther(Class<A> otherClass, BiJoiner<A,A>... joiners)	Create a new UniDataStream for every A, if another A exists that does not Object.equals(Object) the first, and for which the BiJoiners are true (for the properties they extract from both facts).
<B> UniDataStream<Solution_,A>	ifNotExists(UniDataStream<Solution_,B> otherStream, BiJoiner<A,B>... joiners)	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).
<B> UniDataStream<Solution_,A>	ifNotExists(Class<B> otherClass, BiJoiner<A,B>... joiners)	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).
default UniDataStream<Solution_,A>	ifNotExistsOther(Class<A> otherClass, BiJoiner<A,A>... joiners)	Create a new UniDataStream for every A, if no other A exists that does not Object.equals(Object) the first, for which the BiJoiners are true (for the properties they extract from both facts).

Method Details

filter

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

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

ifExists

<B> UniDataStream<Solution_,A> ifExists(Class<B> otherClass,
 BiJoiner<A,B>... joiners)

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

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

<B> UniDataStream<Solution_,A> ifExists(UniDataStream<Solution_,B> otherStream,
 BiJoiner<A,B>... joiners)

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

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

ifExistsOther

default UniDataStream<Solution_,A> ifExistsOther(Class<A> otherClass,
 BiJoiner<A,A>... joiners)

Create a new UniDataStream for every A, if another A exists that does not Object.equals(Object) the first, and for which the BiJoiners are true (for the properties they extract from both facts).

Returns:

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

ifNotExists

<B> UniDataStream<Solution_,A> ifNotExists(Class<B> otherClass,
 BiJoiner<A,B>... joiners)

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).

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

<B> UniDataStream<Solution_,A> ifNotExists(UniDataStream<Solution_,B> otherStream,
 BiJoiner<A,B>... joiners)

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).

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

ifNotExistsOther

default UniDataStream<Solution_,A> ifNotExistsOther(Class<A> otherClass,
 BiJoiner<A,A>... joiners)

Create a new UniDataStream for every A, if no other A exists that does not Object.equals(Object) the first, for which the BiJoiners are true (for the properties they extract from both facts).

Returns:

a stream that matches every A where a different A does not exist
