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.
