List::Objects::WithUtils::Array::Typed - Type-checking array objects
use List::Objects::WithUtils 'array_of'; use Types::Standard -all; use List::Objects::Types -all; my $arr = array_of( Int() => 1 .. 10 ); $arr->push('foo'); # dies, failed type check $arr->push(11 .. 15); # ok my $arr_of_arrs = array_of( ArrayObj ); $arr_of_arrs->push(, ); # ok, coerces to ArrayObj
This module requires Type::Tie.
The first argument passed to the constructor should be a Type::Tiny type:
use Types::Standard -all; my $arr = array_of Str() => qw/foo bar baz/;
Elements are checked against the specified type when the object is constructed or new elements are added.
If the initial type-check fails, a coercion is attempted.
Values that cannot be coerced will throw an exception.
It's worth noting that this comes with the obvious type-checking performance hit, plus some extra overhead in proxying array operations.
Returns the Type::Tiny type the object was created with.
