NAME
MooseX::AttributeHelpers::String - string attribute typeSYNOPSIS
package MyHomePage; use Moose; use MooseX::AttributeHelpers; has 'text' => ( metaclass => 'String', is => 'rw', isa => 'Str', default => sub { '' }, provides => { append => "add_text", replace => "replace_text", } ); 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.If your attribute definition does not include any of is, isa, default or provides but does use the "String" metaclass, then this module applies defaults as in the ``SYNOPSIS'' above. This allows for a very basic counter definition:
has 'foo' => (metaclass => 'String'); $obj->append_foo;
METHODS
- meta
- method_provider
- has_method_provider
- helper_type
- process_options_for_provides
- Run before its superclass method.
- check_provides_values
- Run after its superclass method.
PROVIDED METHODS
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 analogeous 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). 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.
- 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").
