public class KeyStructure<K,V extends SearchStructure<R> & MergeAndCopyStructure<V>,R>
extends AbstractMapStructure<K,V,R>
implements MergeAndCopyStructure<KeyStructure<K,V,R>>

An implementation of AbstractMapStructure mapping keys to nested SearchStructures much like a map. This structure is useful for values that can be identified by their key. The generic types are described in AbstractMapStructure.

Method Summary

KeyStructure<K,V,R>	copy() This method copies the object which calls it.
static <K,V extends SearchStructure<R> & MergeAndCopyStructure<V>,R> KeyStructure<K,V,R>	create() Creates a new empty KeyStructure.
static <K,V extends SearchStructure<R> & MergeAndCopyStructure<V>,R> KeyStructure<K,V,R>	createWith(K key, V value) Creates a new KeyStructure and put the given key value pair.
SearchStructure<R>	get(Object key) Returns the nested SearchStructure for the given key.
void	merge(KeyStructure<K,V,R> map) Merging adds the contents of the otherMergable to this object.

Method Detail

create

public static <K,V extends SearchStructure<R> & MergeAndCopyStructure<V>,R> KeyStructure<K,V,R> create()

Creates a new empty KeyStructure.

createWith

public static <K,V extends SearchStructure<R> & MergeAndCopyStructure<V>,R> KeyStructure<K,V,R> createWith(K key,
                                                                                                          V value)

Creates a new KeyStructure and put the given key value pair.

get

public SearchStructure<R> get(Object key)

Description copied from class: SearchStructure

Returns the nested SearchStructure for the given key. This method never returns null. If no value exists for a given key an EmptySearchStructure is returned as a fall-back.

Specified by:

get in class SearchStructure<R>

Parameters:

key - The key for the requested nested SearchStructure

Returns:

The nested SearchStructure or an EmptySearchStructure if the key does not exist.

merge

public void merge(KeyStructure<K,V,R> map)

Description copied from interface: MergeAndCopyStructure

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.

Specified by:

merge in interface MergeAndCopyStructure<KeyStructure<K,V extends SearchStructure<R> & MergeAndCopyStructure<V>,R>>

Parameters:

map - The object that should be merged into this object

copy

public KeyStructure<K,V,R> copy()

Description copied from interface: MergeAndCopyStructure

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

Specified by:

copy in interface MergeAndCopyStructure<KeyStructure<K,V extends SearchStructure<R> & MergeAndCopyStructure<V>,R>>

Returns:

T that is a copy of the calling object
