NAME
MouseX::NativeTraits::HashRef - Helper trait for HashRef attributes
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',
},
);
DESCRIPTION
This module provides a Hash attribute which provides a number of hash-like operations.
PROVIDED METHODS
These methods are implemented in MouseX::NativeTraits::MethodProvider::HashRef.
get($key, $key2, $key3...)
Returns values from the hash.
In list context return a list of values in the hash for the given keys. In scalar context returns the value for the last key
specified.
set($key => $value, $key2 => $value2...)
Sets the elements in the hash to the given values.
delete($key, $key2, $key3...)
Removes the elements with the given keys.
exists($key)
Returns true if the given key is present in the hash.
defined($key)
Returns true if the value of a given key is defined.
keys
Returns the list of keys in the hash.
sorted_keys
Returns the list of sorted keys in the hash.
values
Returns the list of values in the hash.
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]
";
}
elements
Returns the key/value pairs in the hash as a flattened list.
clear
Resets the hash to an empty value, like "%hash = ()".
count
Returns the number of elements in the hash. Also useful for not empty: "has_options => 'count'".
is_empty
If the hash is populated, returns false. Otherwise, returns true.
accessor
If passed one argument, returns the value of the specified key. If passed two arguments, sets the value of the specified key.
