Description

Pattern for arbitrary set operations of integer generators with point output. For an introduction and more examples see Sieves and Psieve patterns.

Class Methods

PSVop.new(genList, op: 'u', difIndex: 0, maxLength: inf, limit)

Creates a new PSVop object.

Arguments:

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.

op

One of the Symbols 'u', 's', 'sd', 'd' as abbreviations for set operations 'union', 'sect', 'symdif', 'dif' or a Pattern/Stream to produce such. Defaults to 'u'.

difIndex

Integer or a Pattern/Stream to produce such. Determines the generator from which will be subtracted in case of operation 'dif'. Defaults to 0.

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.
