NAME

MooseX::Emulate::Class::Accessor::Fast - Emulate Class::Accessor::Fast behavior using Moose attributes

SYNOPSYS

    package MyClass;
    use Moose;
    with 'MooseX::Emulate::Class::Accessor::Fast';
    #fields with readers and writers
    __PACKAGE__->mk_accessors(qw/field1 field2/);
    #fields with readers only
    __PACKAGE__->mk_ro_accessors(qw/field3 field4/);
    #fields with writers only
    __PACKAGE__->mk_wo_accessors(qw/field5 field6/);

DESCRIPTION

This module attempts to emulate the behavior of Class::Accessor::Fast as accurately as possible using the Moose attribute system. The public API of "Class::Accessor::Fast" is wholly supported, but the private methods are not. If you are only using the public methods (as you should) migration should be a matter of switching your "use base" line to a "with" line.

While I have attempted to emulate the behavior of Class::Accessor::Fast as closely as possible bugs may still be lurking in edge-cases.

BEHAVIOR

Simple documentation is provided here for your convenience, but for more thorough documentation please see Class::Accessor::Fast and Class::Accessor.

A note about introspection

Please note that, at this time, the "is" flag attribute is not being set. To determine the "reader" and "writer" methods using introspection in later versions of Class::MOP ( > 0.38) please use the "get_read_method" and "get_write_method" methods in Class::MOP::Attribute. Example

    # with Class::MOP <= 0.38
    my $attr = $self->meta->find_attribute_by_name($field_name);
    my $reader_method = $attr->reader || $attr->accessor;
    my $writer_method = $attr->writer || $attr->accessor;
    # with Class::MOP > 0.38
    my $attr = $self->meta->find_attribute_by_name($field_name);
    my $reader_method = $attr->get_read_method;
    my $writer_method = $attr->get_write_method;

METHODS

BUILD $self %args

Change the default Moose class building to emulate the behavior of C::A::F and store arguments in the instance hashref.

mk_accessors @field_names

Create read-write accessors. An attribute named $field_name will be created. The name of the c<reader> and "writer" methods will be determined by the return value of "accessor_name_for" and "mutator_name_for", which by default return the name passed unchanged. If the accessor and mutator names are equal the "accessor" attribute will be passes to Moose, otherwise the "reader" and "writer" attributes will be passed. Please see Class::MOP::Attribute for more information.

mk_ro_accessors @field_names

Create read-only accessors.

mk_ro_accessors @field_names

Create write-only accessors.
