AppScopeTrait
=============
.. php:namespace:: atk4\core
.. php:trait:: AppScopeTrait
.. rst-class:: phpdoc-description
| Typical software design will create the application scope\. Most frameworks
| relies on "static" properties, methods and classes\. This does puts some
| limitations on your implementation \(you can\'t have multiple applications\)\.
| App Scope will pass the \'app\' property into all the object that you\'re
| adding, so that you know for sure which application you work with\.

Properties
----------
.. php:attr:: public static _appScopeTrait
.. rst-class:: phpdoc-description
| Check this property to see if trait is present in the object\.

`vendor/atk4/core/src/AppScopeTrait.php#20 <https://github.com/atk4/core/blob/master/vendor/atk4/core/src/AppScopeTrait.php#L20>`_
:Type: bool
.. php:attr:: public static app
.. rst-class:: phpdoc-description
| Always points to current Application\.

`vendor/atk4/core/src/AppScopeTrait.php#27 <https://github.com/atk4/core/blob/master/vendor/atk4/core/src/AppScopeTrait.php#L27>`_
:Type: :any:`\\atk4\\ui\\App <atk4\\ui\\App>`
.. php:attr:: public static max_name_length
.. rst-class:: phpdoc-description
| When using mechanism for ContainerTrait, they inherit name of the
| parent to generate unique name for a child\. In a framework it makes
| sense if you have a unique identifiers for all the objects because
| this enables you to use them as session keys, get arguments, etc\.
| Unfortunately if those keys become too long it may be a problem,
| so ContainerTrait contains a mechanism for auto\-shortening the
| name based around max\_name\_length\. The mechanism does only work
| if AppScopeTrait is used, $app property is set and has a
| max\_name\_length defined\.

| Minimum is 20

:Type: int
.. php:attr:: public static unique_hashes
.. rst-class:: phpdoc-description
| As more names are shortened, the substituted part is being placed into
| this hash and the value contains the new key\. This helps to avoid creating
| many sequential prefixes for the same character sequence\. Those
| hashes can also be used to re\-build the long name of the object, but
| this functionality is not essential and excluded from traits\. You
| can find it in a test suite\.
