Interface MergeAndCopyStructure<T extends MergeAndCopyStructure<T>>

Type Parameters:

T - the type of object that can be copied or merged into this object

All Known Implementing Classes:

KeyStructure, RangeStructure, ResultStructure, TwoColumnRangeStructure, UniqueResultStructure

public interface MergeAndCopyStructure<T extends MergeAndCopyStructure<T>>

Defines the ability to merge or copy other objects into this MergeAndCopyStructure. Used for data structures.

An example of the use of this interface are the subclasses of SearchStructure. They are defined to be mergeable with objects of the same class (or at least similar classes).

Method Summary

Modifier and Type	Method and Description
T	copy() This method copies the object which calls it.
void	merge(T otherMergeable) Merging adds the contents of the otherMergable to this object.

Method Detail

merge

void merge(T otherMergeable)

Merging adds the contents of the otherMergable to this object. This object then contains the combined content. The other object remains unchanged.Merging a SearchStructure deletes no content, instead equal values are being merged recursively.

Parameters:

otherMergeable - The object that should be merged into this object

copy

T copy()

This method copies the object which calls it. The newly created object has the same properties like the object calling copy().

Returns:

T that is a copy of the calling object
