=head1 NAME
MouseX::NativeTraits::HashRef - Helper trait for HashRef attributes
=head1 SYNOPSIS
package Stuff;
use Mouse;
has 'options' => (
traits => ['Hash'],
is => 'ro',
isa => 'HashRef[Str]',
default => sub { {} },
handles => {
set_option => 'set',
get_option => 'get',
has_no_options => 'is_empty',
num_options => 'count',
delete_option => 'delete',
pairs => 'kv',
},
);
=head1 DESCRIPTION
This module provides a Hash attribute which provides a number of
hash-like operations.
=head1 PROVIDED METHODS
These methods are implemented in
L<MouseX::NativeTraits::MethodProvider::HashRef>.
=over 4
=item B<get($key, $key2, $key3...)>
Returns values from the hash.
In list context return a list of values in the hash for the given keys.
In scalar context returns the value for the last key specified.
=item B<set($key =E<gt> $value, $key2 =E<gt> $value2...)>
Sets the elements in the hash to the given values.
=item B<delete($key, $key2, $key3...)>
Removes the elements with the given keys.
=item B<exists($key)>
Returns true if the given key is present in the hash.
=item B<defined($key)>
Returns true if the value of a given key is defined.
=item B<keys>
Returns the list of keys in the hash.
=item B<sorted_keys>
Returns the list of sorted keys in the hash.
=item B<values>
Returns the list of values in the hash.
=item B<kv>
Returns the key/value pairs in the hash as an array of array references.
for my $pair ( $object->options->pairs ) {
print "$pair->[0] = $pair->[1]\n";
}
=item B<elements>
Returns the key/value pairs in the hash as a flattened list.
=item B<clear>
Resets the hash to an empty value, like C<%hash = ()>.
=item B<count>
Returns the number of elements in the hash. Also useful for not empty:
C<< has_options => 'count' >>.
=item B<is_empty>
If the hash is populated, returns false. Otherwise, returns true.
=item B<accessor>
If passed one argument, returns the value of the specified key. If passed two
arguments, sets the value of the specified key.
