/**

 * The context of a validation run.
 | 
						|
 *
 | 
						|
 * The context collects all violations generated during the validation. By
 | 
						|
 * default, validators execute all validations in a new context:
 | 
						|
 *
 | 
						|
 *     $violations = $validator->validate($object);
 | 
						|
 *
 | 
						|
 * When you make another call to the validator, while the validation is in
 | 
						|
 * progress, the violations will be isolated from each other:
 | 
						|
 *
 | 
						|
 *     public function validate(mixed $value, Constraint $constraint): void
 | 
						|
 *     {
 | 
						|
 *         $validator = $this->context->getValidator();
 | 
						|
 *
 | 
						|
 *         // The violations are not added to $this->context
 | 
						|
 *         $violations = $validator->validate($value);
 | 
						|
 *     }
 | 
						|
 *
 | 
						|
 * However, if you want to add the violations to the current context, use the
 | 
						|
 * {@link ValidatorInterface::inContext()} method:
 | 
						|
 *
 | 
						|
 *     public function validate(mixed $value, Constraint $constraint): void
 | 
						|
 *     {
 | 
						|
 *         $validator = $this->context->getValidator();
 | 
						|
 *
 | 
						|
 *         // The violations are added to $this->context
 | 
						|
 *         $validator
 | 
						|
 *             ->inContext($this->context)
 | 
						|
 *             ->validate($value)
 | 
						|
 *         ;
 | 
						|
 *     }
 | 
						|
 *
 | 
						|
 * Additionally, the context provides information about the current state of
 | 
						|
 * the validator, such as the currently validated class, the name of the
 | 
						|
 * currently validated property and more. These values change over time, so you
 | 
						|
 * cannot store a context and expect that the methods still return the same
 | 
						|
 * results later on.
