Method Details

addListener

void addListener(MultisetChangeListener<? super E> listener)

Adds a MultisetChangeListener to this ObservableMultiset. If the same listener is registered more than once, it will be notified more than once.

Parameters:

listener - The MultisetChangeListener to add.

removeListener

void removeListener(MultisetChangeListener<? super E> listener)

Removes a MultisetChangeListener from this ObservableMultiset. Will do nothing if the listener was not attached to this ObservableMultiset. If it was added more than once, then only the first occurrence will be removed.

Parameters:

listener - The MultisetChangeListener to remove.

replaceAll

boolean replaceAll(Multiset<? extends E> multiset)

Replaces all the contents of the ObservableMultiset with the contents provided by the given Multiset.

Parameters:

multiset - The Multiset whose values should be used to replace those of this ObservableMultiset.

Returns:

Whether this map was changed through the replace operation.
