function GenericMetadata::addConstraint

Adds a constraint.

If the constraint {@link Valid} is added, the cascading strategy will be changed to {@link CascadingStrategy::CASCADE}. Depending on the $traverse property of that constraint, the traversal strategy will be set to one of the following:

{@link TraversalStrategy::IMPLICIT} if $traverse is enabled
{@link TraversalStrategy::NONE} if $traverse is disabled

Return value

$this

Throws

ConstraintDefinitionException When trying to add the {@link Cascade} or {@link Traverse} constraint
