Attributes

All attributes are read-only.

"package" ClassName

The package we're providing a signature for. Will be used to look up any stringy type names.

"subname" Str

The sub we're providing a signature for.

"description" Str

"method" ArrayRef[InstanceOf['Type::Params::Parameter']]

"head" ArrayRef[InstanceOf['Type::Params::Parameter']]

"tail" ArrayRef[InstanceOf['Type::Params::Parameter']]

"parameters" ArrayRef[InstanceOf['Type::Params::Parameter']]

"slurpy" InstanceOf['Type::Params::Parameter']

"on_die" CodeRef

"strictness" Bool|ScalarRef

"next" CodeRef

"goto_next" CodeRef

Alias for "next".

"can_shortcut" Bool

Indicates whether the signature has no potential to alter @_ allowing it to be returned without being copied if type checks pass. Generally speaking, you should not provide this to the constructor and rely on Type::Params::Signature to figure it out.

"coderef" InstanceOf['Eval::TypeTiny::CodeAccumulator']

You probably don't want to provide this to the constructor. The whole point of this module is to build it for you!

Attributes related to named parameters

"is_named" Bool

"allow_dash" Bool

"bless" Bool|ClassName

"class" ClassName

"constructor" Str

"class_attributes" HashRef

HashRef suitable for passing to the "import" method of Class::XSAccessor. A default will be generated based on "parameters"

"named_to_list" ArrayRef

Can be coerced from a bool based on "parameters".

"list_to_named" Bool

"oo_trace" Bool

Defaults to true. Indicates whether blessed $arg hashrefs created by the signature will include a '~~caller' key.

Bare attributes

These attributes may be passed to the constructors and may do something, but no methods are provided to access the values later.

"positional" or "pos" ArrayRef

"named" ArrayRef

"multiple" or "multi" ArrayRef

"returns" Bool

Shortcut for setting "returns_scalar" and "returns_list" simultaneously.

"want_source" Bool

"want_details" Bool

"want_object" Bool

"rationalize_slurpies" Bool

Methods

Predicates

Predicate methods return true/false to indicate the presence or absence of attributes.

"has_description"

"has_head"

"has_tail"

"has_parameters"

"has_slurpy"

"has_on_die"

"has_strictness"

"has_returns_scalar"

"has_returns_list"

Class making methods

These methods will be called automatically during object construction and should not typically be called. They are public methods in case it is desired to subclass Type::Params::Signature.

"make_class_pp"

Builds the class specified in "bless" by evaluating Perl code.

"make_class_xs"

Builds the class specified in "bless" using Class::XSAccessor.

"make_class"

Calls either "make_class_pp" or "make_class_xs".

"make_class_pp_code"

Generates the code for "make_class_pp".

Other methods

"BUILD"

Called by the constructors. You should not call this.

"return_wanted"

Normally returns the signature coderef, unless "want_source", "want_details", or "want_object" were provided to the constructor, in which case it will return the source code for the coderef, a hashref of details, or $self.
