- Method Detail
  - getConstrainedContainerElementTypes
```
java.util.Set<ContainerElementTypeDescriptor> getConstrainedContainerElementTypes()
```
    If this element is of a container type, e.g. List or Map, a set of descriptors of those container element types is returned, which are constrained or marked with Valid. A container element type is constrained, if it hosts at least one constraint.
    In the context of properties and method return values, container element types of super-types are considered.
    
    Returns:
    
    the set of descriptors representing the container element types that are constrained or are marked with Valid. An empty set will be returned if this element is not of a container type or is of a container type but there are no container element types hosting constraints or marked with Valid.
