JooseX.Attribute.Accessor.Combined - a role, combining setter and getter methods into one, ala perl

SYNOPSIS

        Class('Some.Class', { 
            has : {
                attr : {
                    is : 'rwc',

                    init : 'some init value'
                }
            }
        })

        var instance = new Some.Class()

        instance.attr() == 'some init value'  // call to combined accessor as getter

        instance.attr('some other value')     // call to combined accessor as setter

        instance.attr() == 'some other value' // attribute was changed

DESCRIPTION

This role combines the getter and setter methods into one, having the same name as attribute itself.

Call this method without arguments will be directed to the actual getter call.

Call with some arguments provided will be directed to setter call.

Its safe to combine this role with Lazy and Trigger, but it should be applied after them.

USAGE

To enable this role provide the trailing c character in attribute's is option:

        has : {
            attr : {
                is : 'rwc',

                init : 'some init value'
            }
        }

Alternatively, explicitly specify isCombined option with some true value:

        has : {
            attr : {
                is : 'rw',

                isCombined : true,

                init : 'some init value'
            }
        }
