#properties ⇒ Hash

Class properties

Examples:

def properties

end

#property(name, type = Object, one_of: nil, assert: ->(_) { true }, allow_nil: false, default: nil) ⇒ void

This method returns an undefined value.

Adds a new “property” to the class

Examples:

property name, type: String, assert: ->(v) { v.length > 3 }, allow_nil: true
property scores, type: [Integer], assert: ->(v) { v >= 0 }, default: []

Parameters:

  • name (Symbol) —

    the property name

  • type (Class, Array<Class>) (defaults to: Object) —

    the expected value or values type

  • one_of (Array) (defaults to: nil) —

    the accepted values

  • assert (Proc) (defaults to: ->(_) { true }) —

    a lambda processing the value and returning true or false

  • allow_nil (true, false) (defaults to: false) —

    allow nil as a value

  • default (Object) (defaults to: nil) —

    default value if not set on initialization
