NAME¶
Specio::Library::Builtins - Implements type constraint objects for Perl's built-in types
VERSION¶
version 0.47
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.
