Creation / Class Methods


*new (genList, maxLength, limit)

Creates a new PSVunion object.

genList - An array of generators. 

Allowed generators: Integers, Streams or Patterns producing intervals or Sieves itself.

Integers and Stream/Pattern output must be strictly positive. 

Integers as generators produce zero and its positive multiples.


maxLength - Integer. Maximum number of items, which the stream will return.

Defaults to inf.


limit - Integer. Limit up to which integers can be returned by the stream.

If no limit is passed, returned integers might go up to default limit 65536.



Examples



p = PSVunion([3, 5], 10)


p.asStream.nextN(15)



a = Sieve(7, 30)


q = PSVunion([a, 100], 10)


q.asStream.all



r = PSVunion([a, 100], limit: 1000)


r.asStream.all
