61 This module provides a Hash attribute which provides a number of
64 =head1 PROVIDED METHODS
68 =item B<get($key, $key2, $key3...)>
70 Returns values from the hash.
72 In list context it returns a list of values in the hash for the given keys. In
73 scalar context it returns the value for the last key specified.
75 This method requires at least one argument.
77 =item B<set($key =E<gt> $value, $key2 =E<gt> $value2...)>
79 Sets the elements in the hash to the given values. It returns the new values
80 set for each key, in the same order as the keys passed to the method.
82 This method requires at least two arguments, and expects an even number of
85 =item B<delete($key, $key2, $key3...)>
87 Removes the elements with the given keys.
89 In list context it returns a list of values in the hash for the deleted
90 keys. In scalar context it returns the value for the last key specified.
94 Returns the list of keys in the hash.
96 This method does not accept any arguments.
100 Returns true if the given key is present in the hash.
102 This method requires a single argument.
104 =item B<defined($key)>
106 Returns true if the value of a given key is defined.
108 This method requires a single argument.
112 Returns the list of values in the hash.
114 This method does not accept any arguments.
118 Returns the key/value pairs in the hash as an array of array references.
120 for my $pair ( $object->options->pairs ) {
121 print "$pair->[0] = $pair->[1]\n";
124 This method does not accept any arguments.
128 Returns the key/value pairs in the hash as a flattened list..
130 This method does not accept any arguments.
134 Resets the hash to an empty value, like C<%hash = ()>.
136 This method does not accept any arguments.
140 Returns the number of elements in the hash. Also useful for not empty:
141 C<< has_options => 'count' >>.
143 This method does not accept any arguments.
147 If the hash is populated, returns false. Otherwise, returns true.
149 This method does not accept any arguments.
151 =item B<accessor($key)>
153 =item B<accessor($key, $value)>
155 If passed one argument, returns the value of the specified key. If passed two
156 arguments, sets the value of the specified key.
158 When called as a setter, this method returns the value that was set.
