| CustomCollectionEditor | back to summary |
|---|---|
| public CustomCollectionEditor(Class<? extends Collection<E>> collectionType, boolean nullAsEmptyCollection) Create a new CustomCollectionEditor for the given target type. If the incoming value is of the given type, it will be used as-is. If it is a different Collection type or an array, it will be converted to a default implementation of the given Collection type. If the value is anything else, a target Collection with that single value will be created. The default Collection implementations are: ArrayList for List, TreeSet for SortedSet, and LinkedHashSet for Set.

| alwaysCreateNewCollection | back to summary |
|---|---|
| protected boolean alwaysCreateNewCollection() Return whether to always create a new Collection, even if the type of the passed-in Collection already matches. Default is "false"; can be overridden to enforce creation of a new Collection, for example to convert elements in any case.

| convertElement | back to summary |
|---|---|
| protected Object convertElement(Object element) Hook to convert each encountered Collection/array element. The default implementation simply returns the passed-in element as-is. Can be overridden to perform conversion of certain elements, for example String to Integer if a String array comes in and should be converted to a Set of Integer objects. Only called if actually creating a new Collection!
This is by default not the case if the type of the passed-in Collection
already matches. Override
