NAME
Mouse::Meta::Attribute - attribute metaclassMETHODS
new %args -> Mouse::Meta::Attribute
new %args -> Mouse::Meta::Attribute
Instantiates a new Mouse::Meta::Attribute. Does nothing else.
create OwnerClass, AttributeName, %args -> Mouse::Meta::Attribute
create OwnerClass, AttributeName, %args -> Mouse::Meta::Attribute
Creates a new attribute in OwnerClass. Accessors and helper methods are installed. Some error checking is done.
name -> AttributeName

is_required -> Bool
default -> Item
has_default -> Bool
is_lazy -> Bool
predicate -> MethodName | Undef
has_predicate -> Bool
clearer -> MethodName | Undef

has_type_constraint -> Bool
trigger => CODE | Undef
has_trigger -> Bool
builder => MethodName | Undef
has_builder -> Bool
is_lazy_build => Bool
should_auto_deref -> Bool
Informational methods.
generate_accessor -> CODE
Creates a new code reference for the attribute's accessor.
generate_predicate -> CODE
Creates a new code reference for the attribute's predicate.
generate_clearer -> CODE
Creates a new code reference for the attribute's clearer.
generate_handles -> { MethodName => CODE }
Creates a new code reference for each of the attribute's handles methods.
find_type_constraint -> CODE
Returns a code reference which can be used to check that a given value passes this attribute's type constraint;
verify_against_type_constraint Item -> 1 | ERROR
Checks that the given value passes this attribute's type constraint. Returns 1 on success, otherwise "confess"es.
canonicalize_args Name, %args -> %args
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
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".
