Method Details

bindContent

public static <E> void bindContent(Multiset<E> source,
 ObservableMultiset<? extends E> target)

Creates a unidirectional content binding from the given source Multiset to the given target ObservableMultiset.

Type Parameters:

E - The element type of the given Multiset and ObservableMultiset.

Parameters:

source - The Multiset whose content to update when the given ObservableMultiset changes.

target - The ObservableMultiset whose content is to be observed.

bindContent

public static <K,
V> void bindContent(SetMultimap<K,V> source,
 ObservableSetMultimap<? extends K,? extends V> target)

Creates a unidirectional content binding from the given source SetMultimap to the given target ObservableSetMultimap.

Type Parameters:

K - The key type of the given SetMultimap and ObservableSetMultimap.

V - The value type of the given SetMultimap and ObservableSetMultimap.

Parameters:

source - The SetMultimap whose content to update when the given ObservableSetMultimap changes.

target - The ObservableSetMultimap whose content is to be observed.

bindContentBidirectional

public static <E> void bindContentBidirectional(ObservableMultiset<E> source,
 ObservableMultiset<E> target)

Creates a bidirectional content binding between the given ObservableMultisets.

Type Parameters:

E - The element type of the given ObservableMultisets.

Parameters:

source - The first participant of the bidirectional binding. Its contents will be initially replaced with that of the second participant before both are synchronized.

target - The second participant of the bidirectional binding. Its contents will be initially taken to update the contents of the first participant before both are synchronized.

bindContentBidirectional

public static <K,
V> void bindContentBidirectional(ObservableSetMultimap<K,V> source,
 ObservableSetMultimap<K,V> target)

Creates a unidirectional content binding between the given ObservableSetMultimaps.

Type Parameters:

K - The key type of the given ObservableSetMultimaps.

V - The value type of the given ObservableSetMultimaps.

Parameters:

source - The first participant of the bidirectional binding. Its contents will be initially replaced with that of the second participant before both are synchronized.

target - The second participant of the bidirectional binding. Its contents will be initially taken to update the contents of the first participant before both are synchronized.

unbindContent

public static <E> void unbindContent(Multiset<E> source,
 ObservableMultiset<? extends E> target)

Removes an existing content binding from the given source Multiset to the given target ObservableMultiset.

Type Parameters:

E - The element types of the Multiset and ObservableMultiset.

Parameters:

source - The Multiset whose content should no longer be updated when the given ObservableMultiset changes.

target - The ObservableMultiset whose content is no longer to be observed.

unbindContent

public static <K,
V> void unbindContent(SetMultimap<K,V> source,
 ObservableSetMultimap<? extends K,? extends V> target)
