public function GenericMetadata::addConstraint in Plug 7

Adds a constraint.

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

• {@link TraversalStrategy::IMPLICIT} if $traverse is enabled and $deep is enabled
• {@link TraversalStrategy::IMPLICIT} | {@link TraversalStrategy::STOP_RECURSION} if $traverse is enabled, but $deep is disabled
• {@link TraversalStrategy::NONE} if $traverse is disabled

Parameters

Constraint $constraint The constraint to add:

Return value

GenericMetadata This object

Throws
