Class Method Details

.type_enum(*input) ⇒ Dry::Types[Enum<Symbol>]

Shorthand to declare type as a enum

Parameters:

• input (Array<Symbol>)

Returns:

• (Dry::Types[Enum<Symbol>])

# File 'lib/drymm/shapes/node.rb', line 53

def type_enum(*input)
  type_identifier(input)
end

.type_identifier(klass) ⇒ Dry::Types::Type .type_identifier(name) ⇒ Dry::Types::Type .type_identifier(list) ⇒ Dry::Types::Type

Note:

To hook the assigned type identifier for specific subclass, just override this method.

Returns coercible symbol type with specific value — node type identifier (declared, for example, as ‘type` in Drymm::Shape::LogicNode.inherited).

Examples:

Hook the type value

class Something < Drymm::S::Node
  def self.type_identifier(*)
    super(:hooked)
  end
end

Overloads:

• .type_identifier(klass) ⇒ Dry::Types::Type

  Generates identifier from the given class name

  Parameters:

  • klass (Class)
• .type_identifier(name) ⇒ Dry::Types::Type

  Coerces the given name to symbol and uses it as a node type identifier

  Parameters:

  • name (#to_sym)
• .type_identifier(list) ⇒ Dry::Types::Type

  Builds Dry::Types::Enum from the given list of values

  Parameters:

  • list (Array)

Returns:

• (Dry::Types::Type) —

  coercible symbol type with specific value — node type identifier (declared, for example, as ‘type` in Drymm::Shape::LogicNode.inherited)
