NAME
       Moose::Meta::Attribute::Native::Trait::String - Helper trait for Str attributes

VERSION
       version 2.0604

SYNOPSIS
         package MyHomePage;
         use Moose;

         has 'text' => (
             traits  => ['String'],
             is      => 'rw',
             isa     => 'Str',
             default => q{},
             handles => {
                 add_text     => 'append',
                 replace_text => 'replace',
             },
         );

         my $page = MyHomePage->new();
         $page->add_text("foo");    # same as $page->text($page->text . "foo");

DESCRIPTION
       This trait provides native delegation methods for strings.

DEFAULT TYPE
       If you don't provide an "isa" value for your attribute, it will default to "Str".

PROVIDED METHODS
       •   inc

           Increments the value stored in this slot using the magical string autoincrement operator. Note
           that Perl doesn't provide analogous behavior in "--", so "dec" is not available. This method
           returns the new value.

           This method does not accept any arguments.

       •   append($string)

           Appends to the string, like ".=", and returns the new value.

           This method requires a single argument.

       •   prepend($string)

           Prepends to the string and returns the new value.

           This method requires a single argument.

       •   replace($pattern, $replacement)

           Performs a regexp substitution ("s" in perlop). There is no way to provide the "g" flag, but code
           references will be accepted for the replacement, causing the regex to be modified with a single
           "e". "/smxi" can be applied using the "qr" operator. This method returns the new value.

           This method requires two arguments.

       •   match($pattern)

           Runs the regex against the string and returns the matching value(s).

           This method requires a single argument.

       •   chop

           Just like "chop" in perlfunc. This method returns the chopped character.

           This method does not accept any arguments.

       •   chomp

           Just like "chomp" in perlfunc. This method returns the number of characters removed.

           This method does not accept any arguments.

       •   clear

           Sets the string to the empty string (not the value passed to "default").

           This method does not have a defined return value.

           This method does not accept any arguments.

       •   length

           Just like "length" in perlfunc, returns the length of the string.

       •   substr

           This acts just like "substr" in perlfunc. When called as a writer, it returns the substring that
           was replaced, just like the Perl builtin.

           This method requires at least one argument, and accepts no more than three.
