Method: Type::Definition#initialize

Defined in:
lib/type/definition.rb

#initialize(name = nil, parent = nil, &block) ⇒ Object

Create a new Type::Definition

You should never have to use Type::Definition#initialize directly;
instead use Type::Definition::generate()

Parameters:

  • name (Symbol) (defaults to: nil) —

    (nil) Capital-letter symbol (e.g., :Int32) for which to register this definition globally. If defining a Type::Definition with name :FooBar, the following are registerde:

    - `Type::FooBar`: a reference to the `Type::Definition`
- `Type::FooBar()`: an alias to `Type::FooBar::cast!()`
- `Type::FooBar?()`: an alias to `Type::FooBar::validate?()`
  • parent (Symbol, Type::Definition) (defaults to: nil) —

    A parent Type::Definition whose validation and casting is done before it is done in self. See the builtin Type::Int32 for an example.
