NAME

       Parse::Method::Signatures::TypeConstraint - turn parsed TC data into Moose TC object

DESCRIPTION

       Class used to turn PPI elements into Moose::Meta::TypeConstraint objects.

ATTRIBUTES

   tc
	   Lazy Build.

       The Moose::Meta::TypeConstraint object for this type constraint, built when requested. "tc_callback" will be called for each individual
       component type in turn.

   tc_callback
	   Type: CodeRef

	   Default: "find_registered_constraint"

       Callback used to turn type names into type objects. See "type_constraint_callback" in Parse::Method::Signatures for more details and an
       example.

   from_namespace
	   Type: ClassName

       If provided, then the default "tc_callback" will search for MooseX::Types in this package.

METHODS

   find_registered_constraint
       Will search for an imported MooseX::Types in "from_namespace" (if provided). Failing that it will ask the
       Moose::Meta::TypeConstraint::Registry for a type with the given name.

       If all else fails, it will simple return the type as a string, so that Moose's auto-vivification of classnames to type will work.

   to_string
       String representation of the type constraint, approximately as parsed.

NAME

       Parse::Method::Signatures::Param - a parsed parameter from a signature

ATTRIBUTES

       All attributes of this class are read-only.

   required
       Is this parameter required (true) or optional (false)?

   sigil
       The effective sigil ('$', '@' or '%') of this parameter.

   type_constraints
	   Type: Parse::Method::Signatures::TypeConstraint

	   Predicate: has_type_constraints

       Representation of the type constraint for this parameter. Most commonly you will just call "meta_type_constraint" and not access this
       attribute directly.

   default_value
	   Type: Str

	   Predicate: has_default_value

       A string that should be eval'd or injected to get the default value for this parameter. For example:

	$name = 'bar'

       Would give a default_value of "'bar'".

   constraints
	   Type: ArrayRef[Str]

	   Predicate: has_constraints

       "where" constraints for this type. Each member of the array a the string (including enclosing braces) of the where constraint block.

   param_traits
	   Type: ArrayRef[ Tupple[Str,Str] ]

	   Predicate: has_traits

       Traits that this parameter is declared to have. For instance

	$foo does coerce

       would have a trait of

	['does', 'coerce']

METHODS

   to_string
   meta_type_constraint
       Get the Moose::Meta::TypeConstraint for this parameter. Check first that the type has a type constraint:

	$tc = $param->meta_type_constraint if $param->has_type_constraints;
