Class ListMergeBehavior<T extends List>

java.lang.Object

com.alee.api.merge.behavior.ListMergeBehavior<T>

Type Parameters:

T - List type

All Implemented Interfaces:

GlobalMergeBehavior<T,T,T>, Serializable

public class ListMergeBehavior<T extends List>
extends Object
implements GlobalMergeBehavior<T,T,T>

Smart List merge behavior that tracks `Identifiable` elements It will attempt to find identifiable elements in list and merge them. Other elements will simply be added to the end of the list in provided order. This is the best way we can handle list elements merge without any additional information on the elements.

Description copied from interface: GlobalMergeBehavior

Returns whether or not this behavior supports specified objects merge.

Specified by:

supports in interface GlobalMergeBehavior<T extends List,T extends List,T extends List>

Parameters:

merge - RecursiveMerge algorithm

type - expected resulting object Class type

base - base object, should never be null

merged - object to merge, should never be null

base - base object, should never be null

merged - object to merge, should never be null

depth - merge calls stack depth

Returns:

merge result
