MooseX::AttributeShortcuts::Trait::Attribute(3) User Contributed Perl Documentation MooseX::AttributeShortcuts::Trait::Attribute(3)

MooseX::AttributeShortcuts::Trait::Attribute - Shortcuts attribute trait proper

This document describes version 0.037 of MooseX::AttributeShortcuts::Trait::Attribute - released November 20, 2017 as part of MooseX-AttributeShortcuts.

This is the actual attribute trait that implements MooseX::AttributeShortcuts. You should consult that package's documentation for information on any of the new attribute options; we're mainly going to document the additional attributes, methods, and role parameters that this role provides.
All methods we include that chain off Moose's "_process_options()" are prefixed with "_mxas_" and generally are not documented in the POD; we document any internal methods of Moose::Meta::Attribute that we wrap or otherwise override we document here as well.

Parameterized roles accept parameters that influence their construction. This role accepts the following parameters.

CodeRef, read-only.

Contains the name of the method that will be invoked as a trigger.

Here we wrap _process_options() instead of the newer _process_is_option(), as that makes our life easier from a Moose 1.x/2.x compatibility perspective -- and that we're generally altering more than just the 'is' option at one time.

Here we create and install any custom accessors that have been defined.

We hijack attach_to_class in order to install our anon_builder, if we have one. Note that we don't go the normal associate_method/install_accessor/etc route as this is kinda... different. (That is, the builder is not an accessor of this attribute, and should not be installed as such.)

Predicate for the "constraint" attribute.

Predicate for the "original_isa" attribute.

Predicate for the "trigger_method" attribute.

Returns the metaclass we'll use to install a inline builder.

Returns the writer prefix; this is almost always "set_".

Returns the builder prefix; this is almost always "_build_".

We accept two parameters on the use of this module; they impact how builders and writers are named.

    use MooseX::::AttributeShortcuts -writer_prefix => 'prefix';
The default writer prefix is "_set_". If you'd prefer it to be something else (say, "_"), this is where you'd do that.

    use MooseX::AttributeShortcuts -builder_prefix => 'prefix';
The default builder prefix is "_build_", as this is what "lazy_build" in Moose does, and what people in general recognize as build methods.

Please see those modules/websites for more information related to this module.
