.. rst-class:: phpdoctorst .. role:: php(code) :language: php 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\. :Source: `vendor/atk4/core/src/AppScopeTrait.php#13 <>`_ Properties ---------- .. php:attr:: public static _appScopeTrait .. rst-class:: phpdoc-description | Check this property to see if trait is present in the object\. :Source: `vendor/atk4/core/src/AppScopeTrait.php#20 <>`_ :Type: bool .. php:attr:: public static app .. rst-class:: phpdoc-description | Always points to current Application\. :Source: `vendor/atk4/core/src/AppScopeTrait.php#27 <>`_ :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 | | See http://stackoverflow\.com/a/9399615/1466341 for more info\. :Source: `vendor/atk4/core/src/AppScopeTrait.php#47 <>`_ :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\. :Source: `vendor/atk4/core/src/AppScopeTrait.php#59 <>`_ :Type: array
