```
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

```
    Description copied from interface: BiConstraintStream
    
    Create a new TriConstraintStream for every combination of [A, B] and C for which the TriJoiner is true (for the properties it extracts from both facts).
    Important: This is faster and more scalable than a join followed by a filter, because it applies hashing and/or indexing on the properties, so it doesn't create nor checks every combination of [A, B] and C.
    
    Specified by:
    
    join in interface BiConstraintStream<Solution_,A>
    
    Type Parameters:
    
    C - the type of the third matched fact
    
    Parameters:
    
    otherStream - never null
    
    joiner - never null

    never null, a stream that matches every combination of [A, B] and C for which the TriFunction is true

```
    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:

```
    Description copied from interface: BiConstraintStream
    
    Combines the semantics of BiConstraintStream.groupBy(BiFunction, BiFunction) and BiConstraintStream.groupBy(BiConstraintCollector). That is, the first three facts in the tuple follow the BiConstraintStream.groupBy(BiFunction, BiFunction) semantics. The final fact is the result of applying the first BiConstraintCollector.finisher() on all the tuples of the original BiConstraintStream that belong to the group.
    
    Specified by:
    
    groupBy in interface BiConstraintStream<Solution_,A>
    
    Type Parameters:
    
    GroupKeyA_ - the type of the first fact in the destination QuadConstraintStream's tuple
    
    GroupKeyB_ - the type of the second fact in the destination QuadConstraintStream's tuple
    
    GroupKeyC_ - the type of the third fact in the destination QuadConstraintStream's tuple
    
    ResultContainerD_ - the mutable accumulation type (often hidden as an implementation detail)
    
    ResultD_ - the type of the fourth fact in the destination QuadConstraintStream's tuple
    
    Parameters:
    
    groupKeyAMapping - never null, function to convert the original tuple into a first fact
    
    groupKeyBMapping - never null, function to convert the original tuple into a second fact
    
    groupKeyCMapping - never null, function to convert the original tuple into a third fact
    
    collectorD - never null, the collector to perform the grouping operation with See ConstraintCollectors for common operations, such as count(), sum() and others.
    
    Returns:
    
    never null

```
    Description copied from interface: BiConstraintStream
    
    Convert the BiConstraintStream to a QuadConstraintStream, consisting of unique tuples with four facts.
    The first fact is the return value of the first group key mapping function, applied on the incoming tuple. The second fact is the return value of the second group key mapping function, applied on all incoming tuples with the same first fact. The third fact is the return value of the third group key mapping function, applied on all incoming tuples with the same first fact. The fourth fact is the return value of the fourth group key mapping function, applied on all incoming tuples with the same first fact.
    
    Specified by:
    
    groupBy in interface BiConstraintStream<Solution_,A>
    
    Type Parameters:
    
    GroupKeyA_ - the type of the first fact in the destination QuadConstraintStream's tuple
    
    GroupKeyB_ - the type of the second fact in the destination QuadConstraintStream's tuple
    
    GroupKeyC_ - the type of the third fact in the destination QuadConstraintStream's tuple
    
    GroupKeyD_ - the type of the fourth fact in the destination QuadConstraintStream's tuple
    
    Parameters:
    
    groupKeyAMapping - never null, function to convert the original tuple into a first fact
    
    groupKeyBMapping - never null, function to convert the original tuple into a second fact
    
    groupKeyCMapping - never null, function to convert the original tuple into a third fact
    
    groupKeyDMapping - never null, function to convert the original tuple into a fourth fact
    
    Returns:
    
    never null

public <ResultA_> UniConstraintStream<ResultA_> map(BiFunction<A,B,ResultA_> mapping)
```
    Description copied from interface: BiConstraintStream
    
    As defined by UniConstraintStream.map(Function).
    
    Specified by:
    
    map in interface BiConstraintStream<Solution_,A>
    
    Type Parameters:
    
    ResultA_ - the type of the only fact in the resulting UniConstraintStream's tuple
    
    Parameters:
    
    mapping - never null, function to convert the original tuple into the new tuple
    
    Returns:
    
    never null
  - 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
    
    Parameters:
    
    mapping - never null, function to convert the last fact in the original tuple into Iterable
    
    Returns:
    
    never null
