Method Details

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 <B> BiConstraintStream<A,B> join(UniConstraintStream<B> 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 <B> BiConstraintStream<A,B> join(UniConstraintStream<B> 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 <B> BiConstraintStream<A,B> join(UniConstraintStream<B> 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:

never null, a stream that matches every combination of A and B for which all the joiners are true

join

default <B> BiConstraintStream<A,B> join(UniConstraintStream<B> otherStream,
 BiJoiner<A,B> joiner1,
 BiJoiner<A,B> joiner2,
 BiJoiner<A,B> joiner3)

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

joiner3 - never null

Returns:

never null, a stream that matches every combination of A and B for which all the joiners are true

join

default <B> BiConstraintStream<A,B> join(UniConstraintStream<B> otherStream,
 BiJoiner<A,B> joiner1,
 BiJoiner<A,B> joiner2,
 BiJoiner<A,B> joiner3,
 BiJoiner<A,B> joiner4)

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

joiner3 - never null

joiner4 - never null

Returns:

never null, a stream that matches every combination of A and B for which all the joiners are true

join

<B> BiConstraintStream<A,B> join(UniConstraintStream<B> 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 <B> BiConstraintStream<A,B> join(Class<B> 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

join

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.

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 at 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].

Use with caution, as the increased memory allocation rates coming from tuple creation may negatively affect performance.

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. For performance, returning an implementation of Collection is preferred.

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

concat

UniConstraintStream<A> concat(UniConstraintStream<A> otherStream)

Returns a new UniConstraintStream containing all the tuples of both this UniConstraintStream and the provided UniConstraintStream. Tuples in both this UniConstraintStream and the provided UniConstraintStream will appear at least twice.

For instance, if this stream consists of [A, B, C] and the other stream consists of [C, D, E], this.concat(other) will consist of [A, B, C, C, D, E]. This operation can be thought of as an or between streams.

Parameters:

otherStream - never null

Returns:

never null

concat

default <B> BiConstraintStream<A,B> concat(BiConstraintStream<A,B> otherStream)

Returns a new BiConstraintStream containing all the tuples of both this UniConstraintStream and the provided BiConstraintStream. The UniConstraintStream tuples will be padded from the right by null.

For instance, if this stream consists of [A, B, C] and the other stream consists of [(C1, C2), (D1, D2), (E1, E2)], this.concat(other) will consist of [(A, null), (B, null), (C, null), (C1, C2), (D1, D2), (E1, E2)].

This operation can be thought of as an or between streams.

Parameters:

otherStream - never null

Returns:

never null

concat

<B> BiConstraintStream<A,B> concat(BiConstraintStream<A,B> otherStream,
 Function<A,B> paddingFunctionB)

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

For instance, if this stream consists of [A, B, C] and the other stream consists of [(C1, C2), (D1, D2), (E1, E2)], this.concat(other, a -> null) will consist of [(A, null), (B, null), (C, null), (C1, C2), (D1, D2), (E1, E2)].

This operation can be thought of as an or between streams.

Parameters:

otherStream - never null

paddingFunctionB - never null, function to find the padding for the second fact

Returns:

never null

concat

default <B,
C> TriConstraintStream<A,B,C> concat(TriConstraintStream<A,B,C> otherStream)

Returns a new TriConstraintStream containing all the tuples of both this UniConstraintStream and the provided TriConstraintStream. The UniConstraintStream tuples will be padded from the right by null.

For instance, if this stream consists of [A, B, C] and the other stream consists of [(C1, C2, C3), (D1, D2, D3), (E1, E2, E3)], this.concat(other) will consist of [(A, null), (B, null), (C, null), (C1, C2, C3), (D1, D2, D3), (E1, E2, E3)].
