struct

Croupier::Task::Inputs

Inherits Enumerable < Struct < Value < Object

A read-only view of a task's inputs. Runs read input sets without locks, so additions go through TaskManager.add_input, which locks and defers them until the run ends; there's no removal.

Constructors

new(task : Task)

Source

Instance methods

<<(input : String) : self

Same as TaskManager.add_input on this task

Source

add(input : String) : Bool

Same as TaskManager.add_input on this task: false if the task already had the input

Source

each

Must yield this collection's elements to the block.

Source

empty?

Returns true if self does not contain any element.

([] of Int32).empty? # => true
([1]).empty?         # => false
[nil, false].empty?  # => false

#present? returns the inverse.

Source

includes?(input : String) : Bool

Source

inspect(io : IO) : Nil

Appends this struct's name and instance variables names and values to the given IO.

struct Point
  def initialize(@x : Int32, @y : Int32)
  end
end

p1 = Point.new 1, 2
p1.to_s    # "Point(@x=1, @y=2)"
p1.inspect # "Point(@x=1, @y=2)"

Source

size

Returns the number of elements in the collection.

[1, 2, 3, 4].size # => 4

Source

to_s(io : IO) : Nil

Same as #inspect(io).
