/**
* 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($value, Constraint $constraint)
* {
* $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($value, Constraint $constraint)
* {
* $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.
