# NAME
Simple::Accessor - very simple, light and powerful accessor

# VERSION

version 1.02

# DESCRIPTION

Simple::Accessor provides a simple object layer without any dependency.
It can be used where other ORM could be considered too heavy.
But it has also the main advantage to only need one single line of code.

It can be easily used in scripts...

# Usage

Create a package and just call Simple::Accessor.
The new method will be imported for you, and all accessors will be directly
accessible.

    package MyClass;

    # that s all what you need ! no more line required
    use Simple::Accessor qw{foo bar cherry apple};

You can now call 'new' on your class, and create objects using these attributes

    package main;    
    use MyClass;

    my $o = MyClass->new() 
        or MyClass->new(bar => 42) 
        or MyClass->new(apple => 'fruit', cherry => 'fruit', banana => 'yummy');

You can get / set any value using the accessor

    is $o->bar(), 42;
    $o->bar(51);
    is $o->bar(), 51;
    

You can provide your own init method that will be call by new with default args.
This is optional.

    package MyClass;

    sub build { # previously known as initialize
        my ($self, %opts) = @_;
        
        $self->foo(12345);
    }

You can also provide individual builders / initializers 

    sub _build_bar { # previously known as _initialize_bar
        # will be used if no value has been provided for bar
        1031;
    }

    sub _build_cherry {
        'red';
    }

You can even use a very basic but useful hook system.
Any false value return by before or validate, will stop the setting process.
Be careful with the after method, as there is no protection against infinite loop.

    sub _before_foo {
        my ($self, $v) = @_;
    
        # do whatever you want with $v
        return 1 or 0;
    }

    sub _validate_foo {
        my ($self, $v) = @_;
        # invalid value ( will not be set )
        return 0 if ( $v == 42);
        # valid value
        return 1;        
    }

    sub _after_cherry {
        my ($self) = @_;
        
        # use the set value for extra operations
        $self->apple($self->cherry());
    }
    

# METHODS

None. The only public method provided is the classical import.
