Constructor Detail

LoggingScheduledFuture

public LoggingScheduledFuture(java.util.concurrent.RunnableScheduledFuture<V> future,
                              boolean resultRelevant,
                              java.util.logging.Logger logger)

Creates a new future wrapping the designated RunnableScheduledFuture logging the outcome of the future if no one has retrieved it.

Parameters:

future - The RunnableScheduledFuture which to wrap.

resultRelevant - Whether the result of the future is relevant and therefore it should be logged if it is not retrieved.

logger - The logger for logging unhandled results, Exception, RuntimeException or Error.

Method Detail

getWrappedFutureRunnable

protected java.util.concurrent.RunnableScheduledFuture<V> getWrappedFutureRunnable()

Description copied from class: LoggingFuture

Gets the wrapped future runnable. This is useful for subclasses requiring a more specific object.

Overrides:

getWrappedFutureRunnable in class LoggingFuture<V>

Returns:

The wrapped future runnable.

getDelay

public long getDelay(java.util.concurrent.TimeUnit unit)

Specified by:

getDelay in interface java.util.concurrent.Delayed

isPeriodic

public boolean isPeriodic()

Specified by:

isPeriodic in interface java.util.concurrent.RunnableScheduledFuture<V>

cancel

public boolean cancel(boolean mayInterruptIfRunning)

Specified by:

cancel in interface java.util.concurrent.Future<V>

Overrides:

cancel in class LoggingFuture<V>

compareTo

public int compareTo(java.util.concurrent.Delayed o)

Specified by:

compareTo in interface java.lang.Comparable<java.util.concurrent.Delayed>
