NAME

Coat::Types -- Type constraints handling for Coat

DESCRIPTION

Attributes in Coat are bound to types with the keyword 'isa'. This lets Coat perform type-constraint validation when a value is set to an attribute of the class.

The following types are supported by Coat (based on the ones provided by Moose, those that are not available in Moose are marked 'C')

    Any
    Item
      Bool
      Undef
      Defined
        Value
          Num
            Int
              Timestamp (C)
          Str
            ClassName
        Ref
          ScalarRef
          ArrayRef
          HashRef
          CodeRef

Each of these types provides a static method called "is_valid" which takes a value and returns a boolean telling if the value given is valid according to the type.

METHODS

validate

This module provides a method for validating a value set to an attribute. It calls the appropriate "is_valid" method according to the type given.

If the type given is not a known type, it will be assumed this is a classname, and the value will then be checked with ClassName->is_valid.
