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.

NAME

       Config::Model::HashId - Handle hash element for configuration model

VERSION

       version 2.021

SYNOPSIS

       See "SYNOPSIS" in Config::Model::AnyId

DESCRIPTION

       This class provides hash elements for a Config::Model::Node.

       The hash index can either be en enumerated type, a boolean, an integer or a string.

CONSTRUCTOR

       HashId object should not be created directly.

Hash model declaration
       See model declaration section from Config::Model::AnyId.

Methods
   get_type
       Returns "hash".

   fetch_size
       Returns the number of elements of the hash.

   firstkey
       Returns the first key of the hash. Behaves like "each" core perl function.

   nextkey
       Returns the next key of the hash. Behaves like "each" core perl function.

   swap ( key1 , key2 )
       Swap the order of the 2 keys. Ignored for non ordered hash.

   move ( key1 , key2 )
       Rename key1 in key2.

   move_after ( key_to_move [ , after_this_key ] )
       Move the first key after the second one. If the second parameter is omitted, the first key is placed in first position. Ignored for non
       ordered hash.

   move_up ( key )
       Move the key up in a ordered hash. Attempt to move up the first key of an ordered hash will be ignored. Ignored for non ordered hash.

   move_down ( key )
       Move the key down in a ordered hash. Attempt to move up the last key of an ordered hash will be ignored. Ignored for non ordered hash.

   load_data ( hash_ref | array_ref )
       Load check_list as a hash ref for standard hash.

       Ordered hash should be loaded with an array ref or with a hash containing a special "__order" element. E.g. loaded with either:

	 [ a => 'foo', b => 'bar' ]

       or

	 { __order => ['a','b'], b => 'bar', a => 'foo' }
