public function ExecutionContext::validateValue

Validates a value against a constraint.

Use the parameter <tt>$subPath</tt> to adapt the property path for the validated value. For example, take the following object graph:

<pre> (Person)---($address: Address)---($street: string) ^ </pre>

When the validator validates the <tt>Address</tt> instance, the property path stored in the execution context is "address". When you manually validate the property <tt>$street</tt> now, pass the sub path "street" to adapt the full property path to "address.street":

<pre> $context->validate($address->street, new NotNull(), 'street'); </pre>

Parameters

mixed $value The value to validate.:

Constraint|Constraint[] $constraints The constraint(s) to validate against.:

string $subPath The path to append to the context's property path.:

null|string|string[] $groups The groups to validate in. If you don't pass any: groups here, the current group of the context will be used.
