# MooseX::Emulate::Class::Accessor::Fast(3pm)

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

## 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.

### follow\_best\_practices

Preface readers with 'get\_' and writers with 'set\_'. See original Class::Accessor documentation for more information.

### mutator\_name\_for

### accessor\_name\_for

See original Class::Accessor documentation for more information.

### set

See original Class::Accessor documentation for more information.

### get

See original Class::Accessor documentation for more information.

### meta
