Method Summary

Modifier and Type	Method	Description
Registration	addPropertyChangeListener(PropertyChangeListener listener)
Runnable	addVetoableChangeListener(VetoableChangeListener listener)	Whether to notify listeners
default <O> ObservableCollection<O>	convert(com.google.common.base.Converter<T,O> converter)
default ObservableCollection<T>	filter(Predicate<? super T> predicate)	Replace the content of this collection thereby firing only a single event
default <U> ObservableCollection<T>	map(Function<? super T,? extends U> predicate)
default ObservableValue<T>	mapToValue()	Return a view of this collection as a scalar value: If the collection contains a single item then this item becomes the view's value.

Method Details

addVetoableChangeListener

Runnable addVetoableChangeListener(VetoableChangeListener listener)

Whether to notify listeners

addPropertyChangeListener

Registration addPropertyChangeListener(PropertyChangeListener listener)

filter

default ObservableCollection<T> filter(Predicate<? super T> predicate)

Replace the content of this collection thereby firing only a single event

map

default <U> ObservableCollection<T> map(Function<? super T,? extends U> predicate)

mapToValue

default ObservableValue<T> mapToValue()

Return a view of this collection as a scalar value: If the collection contains a single item then this item becomes the view's value. Otherwise the view's value is null.

Returns:

mapToValue

default <O> ObservableValue<O> mapToValue(Function<? super Collection<? extends T>,O> xform,
 Function<? super O,? extends T> valueToItem)

convert

default <O> ObservableCollection<O> convert(com.google.common.base.Converter<T,O> converter)
