Class ListToTypeAdapter<T,L extends List<?>>

java.lang.Object
  org.omnaest.utils.beans.adapter.ListToTypeAdapter<T,L>

Type Parameters:

T -

L -

public class ListToTypeAdapter<T,L extends List<?>>
extends Object

This class creates a proxy implementation for a given Java Bean type which is used as a facade to an underlying List<?>. Be aware of the fact that only the declared fields of the Class or interface type will affect the List and no access on properties declared by supertypes.

Method Detail

newInstance

public static <T> T newInstance(List<?> list,
                                Class<T> clazz,
                                Comparator<String> comparatorPropertyname,
                                boolean underlyingListAware)

Factory method to create a new ListToTypeAdapter for a given List with the given Class as facade. The list will contain as many elements as properties are possible and for each property an immutable index position is reserved. Within the list the objects will be stored in the order the property names have after invoking the given Comparator on them.

Parameters:

list -

clazz -

comparatorPropertyname -

underlyingListAware - : true > returned stub implements ListToTypeAdapter.UnderlyingListAware

Returns:

new

                                boolean underlyingListAware)

Factory method to create a new ListToTypeAdapter for a given List with the given Class as facade. The list will contain as many elements as properties are possible and for each property an immutable index position is reserved. The objects will be stored in the order of the given List of property names.

Parameters:
