Type Parameters:

T - Map type

All Implemented Interfaces:

GlobalMergeBehavior<T,T,T>, Serializable

public class MapMergeBehavior<T extends Map>
extends Object
implements GlobalMergeBehavior<T,T,T>

todo 1. Provide a different merge behavior similar to ListMergeBehavior for LinkedHashMap

Specified by:

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

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

Returns:

true if this behavior supports specified objects merge, false otherwise

merge

@NotNull
public T merge(@NotNull
                        RecursiveMerge merge,
                        @NotNull
                        Class type,

                        T merged,
                        int depth)

Description copied from interface: GlobalMergeBehavior

Performs merge of the two provided objects and returns resulting object. Depending on the case it might be one of the two provided objects or their merge result.

Specified by:

merge in interface GlobalMergeBehavior<T extends Map,T extends Map,T extends Map>

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

depth - merge calls stack depth

Returns:

merge result
