trait sample extends AnyRef
Sample attribute value(s).
Apply sample
keyword to attribute to return a single sample (random) attribute value of entities matching the molecule.
Person.age.insert(25, 34, 37, 42, 70) Person.age(sample).get.head === 42 // or other..
Apply sample(n)
to return Vector of up to n distinct sample values.
Person.age(sample(3)).get.head === Vector(70, 25, 37) // or other..
If values don't need to be distinct, random(n)
can be used also.

Distinct sample values of attribute.
Distinct sample values of attribute.
Applysample(n)
to an attribute to return a Vector of up to n distinct sample values (can at most return the number of values that match).Person.age.insert(25, 34, 37, 42, 70) Person.age(sample(3)).get.head === Vector(42, 25, 42) // or other..
