Module of DDD pattern.

@class BaseModule
@implements RootInterface
@module base-domain
###
class BaseModule

    constructor: (@name, @path, @facade) ->

    ###*
    is root (to identify RootInterface)
    @property {Boolean} isRoot
    @static
    ###
    @isRoot: true


    ###*
    Get facade

    @deprecated just call facade property
    @method getFacade
    @return {Facade}
    @chainable
    ###
    getFacade: -> @facade


    ###*
    Get module

    @method getModule
    @return {BaseModule}
    ###
    getModule: -> @


    normalizeName: (name) ->
        if not name.match '/'
            return @name + '/' + name

    ###
    getModel: (firstName) ->
        @facade.require @normalizeName firstName

    ###*
    create an instance of the given modFirstName using obj
    if obj is null or undefined, empty object will be created.

        @facade.createService(modFirstName, params...)


    ###*
    create a preferred repository instance
    3rd, 4th ... arguments are the params to pass to the constructor of the repository

    @method createPreferredRepository
    @param {String} modFirstName
    @param {Object} [options]
    @param {Object} [options.noParent] if true, stop requiring parent class
    @return {BaseRepository}
