Class AbstractTuple

java.lang.Object
ai.timefold.solver.constraint.streams.bavet.common.tuple.AbstractTuple
Direct Known Subclasses:
BiTuple, QuadTuple, TriTuple, UniTuple
public abstract sealed class AbstractTuple extends Object permits UniTuple<A>, BiTuple<A,B>, TriTuple<A,B,C>, QuadTuple<A,B,C,D>
A tuple is an out tuple in exactly one node and an in tuple in one or more nodes.

A tuple must not implement equals()/hashCode() to fact equality, because some stream operations (UniConstraintStream.map(Function), ...) might create 2 different tuple instances to contain the same facts and because a tuple's origin may replace a tuple's fact.

A tuple is modifiable. However, only the origin node of a tuple (the node where the tuple is the out tuple) may modify it.
