mousex::nativetraits::str
MouseX::NativeTraits::Str(3pm) User Contributed Perl Documentation MouseX::NativeTraits::Str(3pm)
NAME
MouseX::NativeTraits::Str - Helper trait for Str attributes
SYNOPSIS
package MyHomePage;
use Mouse;
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 module provides a simple string attribute, to which mutating string operations can be applied more easily (no need to make an lvalue
attribute metaclass or use temporary variables). Additional methods are provided for completion.
PROVIDED METHODS
These methods are implemented in MouseX::NativeTraits::MethodProvider::Str. It is important to note that all those methods do in place
modification of the value stored in the attribute.
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.
append($string)
Append a string, like ".=".
prepend($string)
Prepend a string.
replace($pattern, $replacement)
Performs a regexp substitution ("s" in perlop). A code references will be accepted for the replacement, causing the regexp to be
modified with a single "e". "/smxi" can be applied using the "qr" operator.
replace($pattern, $replacement)
Performs a regexp substitution ("s" in perlop) with the "g" flag. A code references will be accepted for the replacement, causing the
regexp to be modified with a single "e". "/smxi" can be applied using the "qr" operator.
match($pattern)
Like "replace" but without the replacement. Provided mostly for completeness.
chop
"chop" in perlfunc
chomp
"chomp" in perlfunc
clear
Sets the string to the empty string (not the value passed to "default").
length
"length" in perlfunc
substr
"substr" in perlfunc. We go to some lengths to match the different functionality based on "substr"'s arity.
METHODS
meta
method_provider_class
helper_type
