NAME
Class::Accessor::Assert - Accessors which type-checkSYNOPSIS
use Class::Accessor::Assert; __PACKAGE__->mk_accessors( qw( +foo bar=Some::Class baz @bits ) );
DESCRIPTION
This is a version of Class::Accessor which offers rudimentary type-checking and existence-checking of arguments to constructors and set accessors.To specify that a member is mandatory in the constructor, prefix its name with a "+". To specify that it needs to be of a certain class when setting that member, suffix "=CLASSNAME". Unblessed reference types such as "=HASH" or "=ARRAY" are acceptable.
To specify that a member is an array, prefix its name with a "@". These members also have the following four special methods that wrap the builtin array operations "push", "pop", "unshift", and "shift":
# for a @bits member: $y->bits_push(@new_values); print $y->bits_pop; $y->bits_unshift(@new_values); print $y->bits_shift;
The "@" can be combined with the "+" prefix to make a member that is an array that you must set in the constructor. The "+" must precede the "@".
# 'foo' is required in the constructor __PACKAGE__->mk_accessors(qw( +@foo ));
