Field Detail

curFut

protected ThreadLocal<IgniteFuture<?>> curFut

Future for previous asynchronous operation.

Constructor Detail

AsyncSupportAdapter

public AsyncSupportAdapter()

Default constructor.

AsyncSupportAdapter

public AsyncSupportAdapter(boolean async)

Parameters:

async - Async enabled flag.

Method Detail

withAsync

public T withAsync()

Gets instance of this component with asynchronous mode enabled.

Specified by:

withAsync in interface IgniteAsyncSupport

Returns:

Instance of this component with asynchronous mode enabled.

createAsyncInstance

protected T createAsyncInstance()

Creates component with asynchronous mode enabled.

Returns:

Component with asynchronous mode enabled.

isAsync

public boolean isAsync()

Specified by:

isAsync in interface IgniteAsyncSupport

Returns:

True if asynchronous mode is enabled.

future

public <R> IgniteFuture<R> future()

Gets and resets future for previous asynchronous operation.

Specified by:

future in interface IgniteAsyncSupport

Type Parameters:

R - Type of the future result.

Returns:

Future for previous asynchronous operation.

future

public <R> IgniteFuture<R> future(boolean reset)

Gets and optionally resets future for previous asynchronous operation.

Parameters:

reset - Specifies whether to reset future.

Returns:

Future for previous asynchronous operation.

saveOrGet

public <R> R saveOrGet(IgniteInternalFuture<R> fut)
                throws IgniteCheckedException

Parameters:

fut - Future.

Returns:

If async mode is enabled saves future and returns null, otherwise waits for future and returns result.

Throws:

IgniteCheckedException - If asynchronous mode is disabled and future failed.

createFuture

protected <R> IgniteFuture<R> createFuture(IgniteInternalFuture<R> fut)

Parameters:

fut - Internal future.

Returns:

Public API future.
