NAME
Specio::Library::Builtins - Implements type constraint objects for Perl's built-in types
VERSION
version 0.40
DESCRIPTION
This library provides a set of types parallel to those provided by Moose.
The types are in the following hierarchy
Item
Bool
Maybe (of `a)
Undef
Defined
Value
Str
Num
Int
ClassName
Ref
ScalarRef (of `a)
ArrayRef (of `a)
HashRef (of `a)
CodeRef
RegexpRef
GlobRef
FileHandle
Object
Item
Accepts any value
Bool
Accepts a non-reference that is "undef", an empty string, 0, or 1. It also accepts any object which overloads boolification.
Maybe (of `a)
A parameterizable type which accepts "undef" or the type "`a". If not parameterized this type will accept any value.
Undef
Only accepts "undef".
Value
Accepts any non-reference value.
Str
Accepts any non-reference value or an object which overloads stringification.
Num
Accepts nearly the same values as "Scalar::Util::looks_like_number", but does not accept numbers with leading or trailing spaces, infinities, or NaN. Also accepts an object which overloads numification.
Int
Accepts any integer value, or an object which overloads numification and numifies to an integer.
ClassName
Accepts any value which passes "Str" where the string is a loaded package.
Ref
Accepts any reference.
ScalarRef (of `a)
Accepts a scalar reference or an object which overloads scalar dereferencing. If parameterized, the dereferenced value must be of type "`a".
ArrayRef (of `a)
Accepts a array reference or an object which overloads array dereferencing. If parameterized, the values in the arrayref must be of type "`a".
HashRef (of `a)
Accepts a hash reference or an object which overloads hash dereferencing. If parameterized, the values in the hashref must be of type "`a".
CodeRef
Accepts a code (sub) reference or an object which overloads code dereferencing.
RegexpRef
Accepts a regex object created by "qr//" or an object which overloads regex interpolation.
GlobRef
Accepts a glob reference or an object which overloads glob dereferencing.
FileHandle
Accepts a glob reference which is an open file handle, any "IO::Handle" Object or subclass, or an object which overloads glob dereferencing and returns a glob reference which is an open file handle.
Object
Accepts any blessed object.
