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

VERSION

version 2.2012

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.
