Overview

A component has a set of inputs an outputs. Every ‘tick` a componnent computes its outputs, but the componnent will wait for the `tock` before the componnent updates its own outputs

Defined Under Namespace

#[](port) ⇒ Input, Output

Gets the teminal assigned to the port

Parameters:

  • port (Symbol) —

    The symbol that represents the terminal

Returns:

def [](port)
  p = @port_mappings[port]
  case p[:type]
  when :input
    @inputs[p[:number]]
  when :output
    @outputs[p[:number]]
  end
end

#[]=(port, terminal) ⇒ Input, Output

Assigns to an input or output

Parameters:

  • port (Symbol) —

    The symbol that represents the terminal

  • terminal (Input, Output) —

    The terminal to assign

Returns:

  • (Input, Output) —

    The terminal that was passed in

  end
end

#initialize(opts = {}) ⇒ Object

Creates the Component with inputs and outputs

Parameters:

  • opts (Hash) (defaults to: {}) —

    options to create the Component with

Options Hash (opts):

  • :inputs (Array<Input>, FixNum) —

    The array of inputs to use, or the number of inputs to create
