Class Summary

Class	Description
ChildrenProviderHasChildren<CHILDTYPE extends IHasChildren<CHILDTYPE>>	A standard implementation of the IChildrenProvider interface that works with all types that implement IHasChildren.
ChildrenProviderHasChildrenSorted<CHILDTYPE extends IHasChildrenSorted<CHILDTYPE>>	An IChildrenProviderSorted implementation for object implementing the IHasChildrenSorted interface.
ChildrenProviderHasChildrenSorting<CHILDTYPE extends IHasChildren<CHILDTYPE>>	An implementation of the IChildrenProvider interface that works with all types that implement IHasChildren.
ChildrenProviderHasChildrenWithID<KEYTYPE,CHILDTYPE extends IHasChildren<CHILDTYPE> & IHasID<KEYTYPE>>	An implementation of the IChildrenProviderWithID interface that works with all types that implement IHasChildren and IHasID.
ChildrenProviderSorting<CHILDTYPE>	An IChildrenProvider that returns the children in ChildrenProviderSorting.getAllChildren(Object) sorted. The implementation wraps an existing children provider and uses and external comparator for sorting.
ChildrenProviderSortingWithID<KEYTYPE,CHILDTYPE>	An IChildrenProviderWithID with ID that returns the children in ChildrenProviderSorting.getAllChildren(Object) sorted.
