 - filter
```
UniConstraintStream<A> filter(Predicate<A> predicate)
```
 Exhaustively test each fact against the Predicate and match if Predicate.test(Object) returns true.
 
 Parameters:
 
 predicate - never null
 
 Returns:
 
 never null
 - join
```
default  BiConstraintStream<A,B> join(UniConstraintStream otherStream)
```
 Create a new BiConstraintStream for every combination of A and B.
 Important: Filtering this is slower and less scalable than a join(UniConstraintStream, BiJoiner), because it doesn't apply hashing and/or indexing on the properties, so it creates and checks every combination of A and B.
 
 Type Parameters:
 
 B - the type of the second matched fact
 
 Parameters:
 
 otherStream - never null
 
 Returns:
 
 never null, a stream that matches every combination of A and B
 - join
```
default  BiConstraintStream<A,B> join(UniConstraintStream otherStream,
 BiJoiner<A,B> joiner)
```
 Create a new BiConstraintStream for every combination of A and B for which the BiJoiner 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 and B.
 
 Type Parameters:
 
 B - the type of the second matched fact
 
 Parameters:
 
 otherStream - never null
 
 joiner - never null
 
 Returns:
 
 never null, a stream that matches every combination of A and B for which the BiJoiner is true
 - join
```
default  BiConstraintStream<A,B> join(UniConstraintStream otherStream,
 BiJoiner<A,B> joiner1,
 BiJoiner<A,B> joiner2)
```
 As defined by join(UniConstraintStream, BiJoiner). For performance reasons, indexing joiners must be placed before filtering joiners.
 
 Type Parameters:
 
 B - the type of the second matched fact
 
 Parameters:
 
 otherStream - never null
 
 joiner1 - never null
 
 joiner2 - never null
 
 Returns:

 Type Parameters:
 
 B - the type of the second matched fact
 
 Parameters:
 
 otherStream - never null
 
 joiner1 - never null

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

<GroupKeyA_,GroupKeyB_,GroupKeyC_> TriConstraintStream<GroupKeyA_,GroupKeyB_,GroupKeyC_> groupBy(Function<A,GroupKeyA_> groupKeyAMapping,
 Function<A,GroupKeyB_> groupKeyBMapping,
 Function<A,GroupKeyC_> groupKeyCMapping)
```
 Convert the UniConstraintStream to a TriConstraintStream, consisting of unique tuples with three 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.
 
 Type Parameters:
 
 GroupKeyA_ - the type of the first fact in the destination TriConstraintStream's tuple; must honor the general contract of hashCode.
 
 GroupKeyB_ - the type of the second fact in the destination TriConstraintStream's tuple; must honor the general contract of hashCode.
 
 GroupKeyC_ - the type of the third fact in the destination TriConstraintStream's tuple; must honor the general contract of hashCode.
 
 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

 Function<A,GroupKeyB_> groupKeyBMapping,
 Function<A,GroupKeyC_> groupKeyCMapping,
 UniConstraintCollector<A,ResultContainerD_,ResultD_> collectorD)
```
 Combines the semantics of groupBy(Function, Function) and groupBy(UniConstraintCollector). That is, the first three facts in the tuple follow the groupBy(Function, Function) semantics. The final fact is the result of applying the first UniConstraintCollector.finisher() on all the tuples of the original UniConstraintStream that belong to the group.

 - map
```
<ResultA_> UniConstraintStream<ResultA_> map(Function<A,ResultA_> mapping)
```
 Transforms the stream in such a way that tuples are remapped using the given function. This may produce a stream with duplicate tuples. See distinct() for details.
 There are several recommendations for implementing the mapping function:
 
 Purity. The mapping function should only depend on its input. That is, given the same input, it always returns the same output.
 
 Bijectivity. No two input tuples should map to the same output tuple, or to tuples that are equal. Not following this recommendation creates a constraint stream with duplicate tuples, and may force you to use distinct() later, which comes with a performance cost.
 
 Immutable data carriers. The objects returned by the mapping function should be identified by their contents and nothing else. If two of them have contents which equal, then they should likewise equal and preferably be the same instance. The objects returned by the mapping function should also be immutable, meaning their contents should not be allowed to change.
 
 Simple example: assuming a constraint stream of tuples of Persons [Ann(age = 20), Beth(age = 25), Cathy(age = 30)], calling map(Person::getAge) on such stream will produce a stream of Integers [20, 25, 30],
 Example with a non-bijective mapping function: assuming a constraint stream of tuples of Persons [Ann(age = 20), Beth(age = 25), Cathy(age = 30), David(age = 30), Eric(age = 20)], calling map(Person::getAge) on such stream will produce a stream of Integers [20, 25, 30, 30, 20].
 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
```
<ResultA_> UniConstraintStream<ResultA_> flattenLast(Function<A,Iterable<ResultA_>> mapping)
```
 Takes each tuple and applies a mapping on it, which turns the tuple into a Iterable. Returns a constraint stream consisting of contents of those iterables. This may produce a stream with duplicate tuples. See distinct() for details.
 In cases where the original tuple is already an Iterable, use Function.identity() as the argument.
 Simple example: assuming a constraint stream of tuples of Persons [Ann(roles = [USER, ADMIN]]), Beth(roles = [USER]), Cathy(roles = [ADMIN, AUDITOR])], calling flattenLast(Person::getRoles) on such stream will produce a stream of [USER, ADMIN, USER, ADMIN, AUDITOR].
 
 Type Parameters:
 
 ResultA_ - the type of facts 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 original tuple into Iterable
 
 Returns:
 
 never null
 - distinct
```
UniConstraintStream<A> distinct()
```
 Transforms the stream in such a way that all the tuples going through it are distinct. (No two tuples will equal.)
 By default, tuples going through a constraint stream are distinct. However, operations such as map(Function) 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

default Constraint impactConfigurable(String constraintName,
 ToIntFunction<A> matchWeigher)
```
 Deprecated, for removal: This API element is subject to removal in a future version.
 Prefer impactConfigurable(ToIntFunction).
 
 Positively or negatively impact the Score by the ConstraintWeight multiplied by the match weight.
 Use penalizeConfigurable(...) or rewardConfigurable(...) instead, unless this constraint can both have positive and negative weights.
 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.
 For non-int Score types use impactConfigurableLong(String, ToLongFunction) or impactConfigurableBigDecimal(String, Function) 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:
