58 This module provides a simple string attribute, to which mutating string
59 operations can be applied more easily (no need to make an lvalue attribute
60 metaclass or use temporary variables). Additional methods are provided for
63 If your attribute definition does not include any of I<is>, I<isa>,
64 I<default> or I<handles> but does use the C<String> metaclass,
65 then this module applies defaults as in the L</SYNOPSIS>
66 above. This allows for a very basic string definition:
68 has 'foo' => (traits => ['String']);
71 =head1 PROVIDED METHODS
73 These methods are implemented in
74 L<Moose::Meta::Attribute::Native::MethodProvider::String>. It is important to
75 note that all those methods do in place modification of the value stored in
82 Increments the value stored in this slot using the magical string autoincrement
83 operator. Note that Perl doesn't provide analogous behavior in C<-->, so
84 C<dec> is not available.
86 =item B<append($string)>
88 Append a string, like C<.=>.
90 =item B<prepend($string)>
94 =item B<replace($pattern, $replacement)>
96 Performs a regexp substitution (L<perlop/s>). There is no way to provide the
97 C<g> flag, but code references will be accepted for the replacement, causing
98 the regex to be modified with a single C<e>. C</smxi> can be applied using the
101 =item B<match($pattern)>
103 Like C<replace> but without the replacement. Provided mostly for completeness.
115 Sets the string to the empty string (not the value passed to C<default>).
123 L<perlfunc/substr>. We go to some lengths to match the different functionality
124 based on C<substr>'s arity.
