Method Details
- filter
  
  public BavetAbstractBiConstraintStream<Solution_,A,B> filter(BiPredicate<A,B> predicate)
  
  Description copied from interface: BiConstraintStream
  
  Exhaustively test each tuple of facts against the BiPredicate and match if BiPredicate.test(Object, Object) returns true.
  Important: This is slower and less scalable than UniConstraintStream.join(UniConstraintStream, BiJoiner) with a proper BiJoiner predicate (such as Joiners.equal(Function, Function), because the latter applies hashing and/or indexing, so it doesn't create every combination just to filter it out.
  
  Specified by:
  
  filter in interface BiConstraintStream<Solution_,A>
  
  Parameters:
  
  predicate - never null
  
  Returns:
  
  never null
- join
  
  @SafeVarargs public final <C> TriConstraintStream<A,B,C> join(UniConstraintStream<C> otherStream, TriJoiner<A,B,C>... joiners)
  
  Description copied from interface: BiConstraintStream
  
  As defined by BiConstraintStream.join(Class, TriJoiner). For performance reasons, indexing joiners must be placed before filtering joiners.
  This method causes Unchecked generics array creation for varargs parameter warnings, but we can't fix it with a SafeVarargs annotation because it's an interface method. Therefore, there are overloaded methods with up to 4 BiJoiner parameters.
  
  Specified by:
  
  join in interface BiConstraintStream<Solution_,A>
  
  Type Parameters:
  
  C - the type of the third matched fact
  
  Parameters:
  
  otherStream - never null
  
  joiners - never null
  
  Returns:
  
  never null, a stream that matches every combination of [A, B] and C for which all the joiners are true
- ifExists
  
  @SafeVarargs public final <C> BiConstraintStream<A,B> ifExists(UniConstraintStream<C> otherStream, TriJoiner<A,B,C>... joiners)
  
  Description copied from interface: BiConstraintStream
  
  As defined by BiConstraintStream.ifExists(UniConstraintStream, TriJoiner). For performance reasons, indexing joiners must be placed before filtering joiners.
  This method causes Unchecked generics array creation for varargs parameter warnings, but we can't fix it with a SafeVarargs annotation because it's an interface method. Therefore, there are overloaded methods with up to 4 TriJoiner parameters.
  
  Specified by:
  
  ifExists in interface BiConstraintStream<Solution_,A>
  
  Type Parameters:
  
  C - the type of the third matched fact
  
  Parameters:
  
  otherStream - never null
  
  joiners - never null
  
  Returns:
  
  never null, a stream that matches every pair of A and B where C exists for which the TriJoiners are true
- ifNotExists
  
  @SafeVarargs public final <C> BiConstraintStream<A,B> ifNotExists(UniConstraintStream<C> otherStream, TriJoiner<A,B,C>... joiners)
  
  Description copied from interface: BiConstraintStream
  
  As defined by BiConstraintStream.ifNotExists(UniConstraintStream, TriJoiner). For performance reasons, indexing joiners must be placed before filtering joiners.
  This method causes Unchecked generics array creation for varargs parameter warnings, but we can't fix it with a SafeVarargs annotation because it's an interface method. Therefore, there are overloaded methods with up to 4 TriJoiner parameters.
  
  Specified by:
  
  ifNotExists in interface BiConstraintStream<Solution_,A>
  
  Type Parameters:
  
  C - the type of the third matched fact
  
  Parameters:
  
  otherStream - never null
  
  joiners - never null
  
  Returns:
  
  never null, a stream that matches every pair of A and B where C does not exist for which the TriJoiners are true

- distinct
  
  public BiConstraintStream<A,B> distinct()
  
  Description copied from interface: BiConstraintStream
  
  Transforms the stream in such a way that all the tuples going through it are distinct. (No two result tuples are equal.)
  By default, tuples going through a constraint stream are distinct. However, operations such as BiConstraintStream.map(BiFunction) may create a stream which breaks that promise. By calling this method on such a stream, duplicate copies of the same tuple are omitted at a performance cost.

  Returns:

  Description copied from interface: BiConstraintStream
  
  Returns a new BiConstraintStream containing all the tuples of both this BiConstraintStream and the provided UniConstraintStream. The UniConstraintStream tuples will be padded from the right by the result of the padding function.

- flattenLast
  
  public <ResultB_> BiConstraintStream<A,ResultB_> flattenLast(Function<B,Iterable<ResultB_>> mapping)
  
  Description copied from interface: BiConstraintStream
  
  Takes each tuple and applies a mapping on the last fact, which turns it into Iterable. Returns a constraint stream consisting of tuples of the first fact and the contents of the Iterable one after another. In other words, it will replace the current tuple with new tuples, a cartesian product of A and the individual items from the Iterable.
  This may produce a stream with duplicate tuples. See BiConstraintStream.distinct() for details.
  In cases where the last fact is already Iterable, use Function.identity() as the argument.
  Simple example: assuming a constraint stream of (PersonName, Person) [(Ann, (name = Ann, roles = [USER, ADMIN])), (Beth, (name = Beth, roles = [USER])), (Cathy, (name = Cathy, roles = [ADMIN, AUDITOR]))], calling flattenLast(Person::getRoles) on such stream will produce a stream of [(Ann, USER), (Ann, ADMIN), (Beth, USER), (Cathy, ADMIN), (Cathy, AUDITOR)].
  
  Specified by:
  
  flattenLast in interface BiConstraintStream<Solution_,A>
  
  Type Parameters:
  
  ResultB_ - the type of the last fact in the resulting tuples. It is recommended that this type be deeply immutable. Not following this recommendation may lead to hard-to-debug hashing issues down the stream, especially if this value is ever used as a group key.
  
  Parameters:
  
  mapping - never null, function to convert the last fact in the original tuple into Iterable. For performance, returning an implementation of Collection is preferred.
  
  Returns:
  
  never null
- expand
  
  public <ResultC_> TriConstraintStream<A,B,ResultC_> expand(BiFunction<A,B,ResultC_> mapping)
  
  Description copied from interface: BiConstraintStream
  
  Adds a fact to the end of the tuple, increasing the cardinality of the stream. Useful for storing results of expensive computations on the original tuple.
  Use with caution, as the benefits of caching computation may be outweighed by increased memory allocation rates coming from tuple creation. If more than two facts are to be added, prefer BiConstraintStream.expand(BiFunction, BiFunction).
  
  Specified by:
  
  expand in interface BiConstraintStream<Solution_,A>
