java.lang.Objectorg.biojava.bio.CollectionConstraint.And
A collection constraint that accpepts collections iff they are accepted by both child constraints. This effectively matches the intersection of the items matched by the two constraints.

subConstraintOf
returns true if the constraint

A pair of constraints super and sub are in a superConstraint/subConstraint relationship if every object accepted by sub is also accepted by super. To put it another way, if instanceOf was used as a set-membership indicator function over some set of objects, then the set produced by super would be a superset of that produced by sub.
It is not expected that constraints will neccesarily
maintain references to super/sub types. It will be more usual
to infer this relationship by introspecting the constraints
themselves. For example,
CollectionConstraint.ByClass
will infer
subConstraintOf by looking at the possible class of all items
matching subConstraint.
