Method Detail

perform

public static <D> void perform(java.awt.Container container,
                               java.lang.Object constraints,
                               com.alee.api.jdk.Supplier<javax.swing.JComponent> loaderSupplier,
                               com.alee.api.jdk.UnsafeSupplier<D> dataSupplier,
                               com.alee.api.jdk.Function<D,javax.swing.JComponent> dataHandler)

Performs lazy UI component load. Also uses error fallback for the case when data load has failed.

Type Parameters:

D - loaded data type

Parameters:

container - container for component

constraints - component constraints

loaderSupplier - loader component supplier, it is executed in EDT

dataSupplier - data supplier, it is executed in a separate thread

dataHandler - data component provider, it is executed in EDT

perform

public static <D> void perform(java.awt.Container container,
                               java.lang.Object constraints,
                               com.alee.api.jdk.Supplier<javax.swing.JComponent> loaderSupplier,
                               com.alee.api.jdk.UnsafeSupplier<D> dataSupplier,
                               com.alee.api.jdk.Function<D,javax.swing.JComponent> dataHandler,
                               com.alee.api.jdk.Function<java.lang.Throwable,javax.swing.JComponent> errorHandler)

Performs lazy UI component load. Also uses error fallback for the case when data load has failed. It will provide temporary loader component in place of final component until its data is fully loaded.

Type Parameters:

D - loaded data type

Parameters:

container - container for component

constraints - component constraints

loaderSupplier - loader component supplier, it is executed in EDT

dataSupplier - data supplier, it is executed in a separate thread

dataHandler - data component provider, it is executed in EDT

errorHandler - error component provider, it is executed in EDT

setExecutorService

public static void setExecutorService(java.util.concurrent.ExecutorService service)

Sets executor service for data loading threads.

Parameters:

service - executor service for data loading threads
