com.iamsoft.util.ui.javafx.collections.AsynchronousMappedList<I,O>

Type Parameters:

I - Input type.

O - Output type.

All Implemented Interfaces:

PermutableObservableList<O>, Iterable<O>, Collection<O>, List<O>, javafx.beans.Observable, javafx.collections.ObservableList<O>

public class AsynchronousMappedList<I,O>
extends ObservableArrayList<O>

ObservableList that transforms elements from 'source' list on a background thread using potentially slow mappers. When a change is made to the source list, the change is reflected in this list at some time in the future. Changes to the list are made in the same order as they appear in the source list.

Constructor Detail

AsynchronousMappedList

public AsynchronousMappedList(javafx.collections.ObservableList<I> pSourceList,
                              Function<I,O> pMapper,
                              Consumer<Runnable> pThreadScheduler)

AsynchronousMappedList

public AsynchronousMappedList(javafx.collections.ObservableList<I> pSourceList,
                              Function<I,S> pPreMapper,
                              Function<S,T> pMapper,
                              Function<T,O> pPostMapper,
                              Consumer<Runnable> pThreadScheduler)

Parameters:

pPreMapper - Invoked on the JavaFX thread before scheduling a mapping task on a background thread. Can be used, for example, to transform mutable input element to immutable object.

pMapper - Invoked on a background thread.

pPostMapper - Invoked on the JavaFX thread after a mapping task is finished. Can be used, for example, to transform immutable intermediate object to mutable output element.

Method Detail

getThreadScheduler

public Consumer<Runnable> getThreadScheduler()

mappingInProgressProperty

public javafx.beans.property.ReadOnlyProperty<Boolean> mappingInProgressProperty()

hasMappingInProgress

public boolean hasMappingInProgress()

createDefaultThreadScheduler

public static Consumer<Runnable> createDefaultThreadScheduler()

Creates a default thread scheduler which executes the specified runnables in a single background thread in order of submission.
