Constants

Any constant value can be passed to annotation, just like if it were used in PHP, by name without quotes:

@MyAnnotation(MY_GLOBAL_CONSTANT)

Also class constants can be used, also with use statements to benefit from short class name.

Example of fully qualified class constant:

...
/**
* @MyAnnotation(MyVendor\MyProject\ClassName::MY_CONSTANT)
*/
public $name;
...

The same example with use statement:

...
use MyVendor\MyProject\ClassName;
...
/**
* @MyAnnotation(ClassName::MY_CONSTANT)
*/
public $name;
...

Addendum will also pre-process special constant prefixes of self and static, to refer to class own constants:

...

const MY_CONSTANT = 1;

/**
* @MyAnnotation(self::MY_CONSTANT)
*/
public $name;
...
