```
TriConstraintStream<A,B,C> filter(TriPredicate<A,B,C> predicate)
```
    Exhaustively test each tuple of facts against the TriPredicate and match if TriPredicate.test(Object, Object, Object) returns true.
    Important: This is slower and less scalable than BiConstraintStream.join(UniConstraintStream, TriJoiner) with a proper TriJoiner predicate (such as Joiners.equal(BiFunction, Function), because the latter applies hashing and/or indexing, so it doesn't create every combination just to filter it out.
    
    Parameters:
    
    predicate - never null
    
    Returns:
    
    never null
  - join
```
default <D> QuadConstraintStream<A,B,C,D> join(UniConstraintStream<D> otherStream)
```
    Create a new QuadConstraintStream for every combination of [A, B, C] and D.
    Important: Filtering this is slower and less scalable than a join(UniConstraintStream, QuadJoiner), because it doesn't apply hashing and/or indexing on the properties, so it creates and checks every combination of [A, B] and C.
    
    Type Parameters:
    
    D - the type of the fourth matched fact
    
    Parameters:
    
    otherStream - never null
    
    Returns:
    
    never null, a stream that matches every combination of [A, B, C] and D
  - join
```
default <D> QuadConstraintStream<A,B,C,D> join(UniConstraintStream<D> otherStream,
                                                                 QuadJoiner<A,B,C,D> joiner)
```
    Create a new QuadConstraintStream for every combination of [A, B] and C for which the QuadJoiner is true (for the properties it extracts from all 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, C] and D.
    
    Type Parameters:
    
    D - the type of the fourth matched fact
    
    Parameters:
    
    otherStream - never null
    
    joiner - never null
    
    Returns:
    
    never null, a stream that matches every combination of [A, B, C] and D for which the QuadJoiner is true
  - join

```
    As defined by join(Class, QuadJoiner). 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 QuadJoiner parameters.
    
    Type Parameters:
    
    D - the type of the fourth matched fact
    
    Parameters:
    
    otherStream - never null
    
    joiners - never null
    
    Returns:
    
    never null, a stream that matches every combination of [A, B, C] and D for which all the joiners are true
  - join
```
default <D> QuadConstraintStream<A,B,C,D> join(Class<D> otherClass)
```
    Create a new QuadConstraintStream for every combination of [A, B, C] and D.
    Important: QuadConstraintStream.filter(QuadPredicate) Filtering} this is slower and less scalable than a join(Class, QuadJoiner), because it doesn't apply hashing and/or indexing on the properties, so it creates and checks every combination of [A, B, C] and D.
    Note that, if a legacy constraint stream uses ConstraintFactory.from(Class) as opposed to ConstraintFactory.forEach(Class), a different range of D may be selected. (See ConstraintFactory.from(Class) Javadoc.)
    This method is syntactic sugar for join(UniConstraintStream).
    
    Type Parameters:
    
    D - the type of the fourth matched fact
    
    Parameters:
    
    otherClass - never null

```
    Convert the TriConstraintStream 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.
    
    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
  - map
```
<ResultA_> UniConstraintStream<ResultA_> map(TriFunction<A,B,C,ResultA_> mapping)
```
    As defined by UniConstraintStream.map(Function).
    
    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
```
<ResultC_> TriConstraintStream<A,B,ResultC_> flattenLast(Function<C,Iterable<ResultC_>> mapping)
```
    As defined by BiConstraintStream.flattenLast(Function).
    
    Type Parameters:
    
    ResultC_ - 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
    
    Returns:
    
    never null
  - distinct
```
TriConstraintStream<A,B,C> distinct()
```
    Removes duplicate tuples from the stream, according to the tuple's facts equals/hashCode methods, such that only distinct tuples remain. (No two tuples will equal.)
    By default, tuples going through a constraint stream are distinct. However, operations such as map(TriFunction) may create a stream which breaks that promise. By calling this method on such a stream, duplicate copies of the same tuple will be omitted at a performance cost.
    
    Returns:
    
    never null

```
    Applies a negative Score impact, subtracting the constraintWeight multiplied by the match weight, and returns a builder to apply optional constraint properties.
    For non-int Score types use penalizeLong(Score, ToLongTriFunction) or penalizeBigDecimal(Score, TriFunction) instead.

    The constraintWeight comes from an ConstraintWeight annotated member on the ConstraintConfiguration, so end users can change the constraint weights dynamically. This constraint may be deactivated if the ConstraintWeight is zero. If there is no ConstraintConfiguration, use ConstraintStream.impact(String, Score) instead.
    The Constraint.getConstraintPackage() defaults to ConstraintConfiguration.constraintPackage().
    
    Parameters:
    
    constraintName - never null, shows up in ConstraintMatchTotal during score justification
    
    matchWeigher - never null, the result of this function (matchWeight) is multiplied by the constraintWeight
    
    Returns:
    
    never null
