NAME

"Tangence::Meta::Type" - structure representing one "Tangence" value type

DESCRIPTION

This data structure object represents information about a type, such as a method or event argument, a method return value, or a property element type.

Due to their simple contents and immutable nature, these objects may be implemented as singletons.

CONSTRUCTOR

$type = Tangence::Meta::Type->new( $primitive )

Returns an instance to represent the given primitive type signature.

$type = Tangence::Meta::Type->new( $aggregate => $member_type )

Returns an instance to represent the given aggregation of the given type instance.

$type = Tangence::Meta::Type->new_from_sig( $sig )

Parses the given full Tangence type signature and returns an instance to represent it.

ACCESSORS

$agg = $type->aggregate

Returns "prim" for primitive types, or the aggregation name for list and dict aggregate types.

$member_type = $type->member_type

Returns the member type for aggregation types. Throws an exception for primitive types.

$sig = $type->sig
