Constructor Details

#initialize(list_of_lists, counts) ⇒ WeightedList

Trims down a list of object lists to given sizes. If there are not enough objects in any particular tier, they are filled up from the tier below/above.

This means there should be 4 :Bs, 8 :Cs, and 8 :Us in the resulting list. But we only have 2 :Bs, so the result is filled up with :Us:

WeightedList.new(list, counts).to_a
# => [
    [:B1, :B2],
    [:C1, :C2, :C3, :C4, :C5, :C6, :C7, :C8],
    [:U1, :U2, :U3, :U4, :U5, :U6, :U7, :U8, :U9, :U10]
  ]

Examples:


list = [
  [:B1, :B2],
  [:C1, :C2, :C3, :C4, :C5, :C6, :C7, :C8, :C9, :C10],
  [:U1, :U2, :U3, :U4, :U5, :U6, :U7, :U8, :U9, :U10]
]
counts = [4, 8, 8]

Parameters:

  • list_of_lists (Array<Array>)
  • counts (Array<Fixnum>)
