Moose::Meta::Attribute::Native::Trait::String - Helper trait for Str attributes
version 2.1003
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");
This trait provides native delegation methods for strings.
If you don't provide an isa value for your attribute, it will default to Str.
isa
Str
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.
--
dec
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.
replace($pattern, $replacement)
Performs a regexp substitution ("s" in perlop). There is no way to provide the g flag, but code references will be accepted for the replacement, causing the regex to be modified with a single e. /smxi can be applied using the qr operator. This method returns the new value.
g
e
/smxi
qr
This method requires two arguments.
match($pattern)
Runs the regex against the string and returns the matching value(s).
chop
Just like "chop" in perlfunc. This method returns the chopped character.
chomp
Just like "chomp" in perlfunc. This method returns the number of characters removed.
clear
Sets the string to the empty string (not the value passed to default).
default
This method does not have a defined return value.
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.
