Method Details

logChannelProcessingDisabled

default void logChannelProcessingDisabled(StorageChannel channel)

logChannelStoppedWorking

default void logChannelStoppedWorking(StorageChannel channel)

logDisruption

default void logDisruption(StorageChannel channel, Throwable t)

Note that not all Throwables are Exceptions. There are also Errors. And not all exceptions are problems. There are also program execution control vehicles like InterruptedException. The actually fitting common term is "Disruption". Throwable is a very low-level technical, compiler-oriented expression.

Parameters:

channel - the affected channel

t - the reason for the disruption

logLiveCheckComplete

default void logLiveCheckComplete(StorageEntityCache<?> entityCache)

logGarbageCollectorSweepingComplete

default void logGarbageCollectorSweepingComplete(StorageEntityCache<?> entityCache)

logGarbageCollectorNotNeeded

default void logGarbageCollectorNotNeeded()

logGarbageCollectorCompletedHotPhase

default void logGarbageCollectorCompletedHotPhase(long gcHotGeneration, long lastGcHotCompletion)

logGarbageCollectorCompleted

default void logGarbageCollectorCompleted(long gcColdGeneration, long lastGcColdCompletion)

logGarbageCollectorEncounteredZombieObjectId

default void logGarbageCollectorEncounteredZombieObjectId(long objectId)

NoOp

static StorageEventLogger NoOp()

Creates a NoOp StorageEventLogger that does really nothing.

Returns:

a StorageEventLogger.NoOp instance

Default

static StorageEventLogger Default()

Creates a Default StorageEventLogger thats prints to the console.

Returns:

a StorageEventLogger.Default instance

Default

static StorageEventLogger Default(Consumer<? super String> messageConsumer)

Creates a Default StorageEventLogger that forwards its output to the supplied Consumer

Parameters:

messageConsumer - a Consumer that processes the forwarded log messages

Returns:

a StorageEventLogger.Default instance

Debug

static StorageEventLogger Debug()

Creates a Debug StorageEventLogger that prints to the console.

Returns:

a StorageEventLogger.Debug instance

Debug

static StorageEventLogger Debug(Consumer<? super String> messageConsumer)

Creates a Debug StorageEventLogger forwards its output to the supplied Consumer

Parameters:

messageConsumer - a Consumer that processes the forwarded log messages

Returns:

a StorageEventLogger.Debug instance
