Informational methods.
verify_against_type_constraint Item -> 1 | ERROR
Checks that the given value passes this attribute's type constraint. Returns 1 on success, otherwise confesses.
canonicalize_args Name, %args -> %args
Canonicalizes some arguments to create. In particular, lazy_build is canonicalized into lazy, builder, etc.
validate_args Name, \%args -> 1 | ERROR
Checks that the arguments to create the attribute (ie those specified by has) are valid.
clone_parent OwnerClass, AttributeName, %args -> Mouse::Meta::Attribute
Creates a new attribute in OwnerClass, inheriting options from parent classes. Accessors and helper methods are installed. Some error checking is done.
get_parent_args OwnerClass, AttributeName -> Hash
Returns the options that the parent class of OwnerClass used for attribute AttributeName.
