Moose::Meta::Attribute::Native::Trait::Hash - Helper trait for HashRef attributes
package Stuff; use Moose; 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', }, );
This module provides a Hash attribute which provides a number of hash-like operations.
These methods are implemented in Moose::Meta::Attribute::Native::MethodProvider::Hash.
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.
Sets the elements in the hash to the given values.
Removes the elements with the given keys.
Returns the list of keys in the hash.
Returns true if the given key is present in the hash.
Returns true if the value of a given key is defined.
Returns the list of values in the hash.
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"; }
Returns the key/value pairs in the hash as a flattened list..
Resets the hash to an empty value, like %hash = ().
%hash = ()
Returns the number of elements in the hash. Also useful for not empty: has_options => 'count'.
has_options => 'count'
If the hash is populated, returns false. Otherwise, returns true.
If passed one argument, returns the value of the specified key. If passed two arguments, sets the value of the specified key.
