Constructor Detail

EventQueue

public EventQueue(long defaultTimeoutInMillis,
                  Consumer<com.github.shyiko.mysql.binlog.event.Event> consumedEvents,
                  Consumer<com.github.shyiko.mysql.binlog.event.Event> ignoredEvents)

Method Detail

defaultEventHandler

private void defaultEventHandler(com.github.shyiko.mysql.binlog.event.Event event)

onEvent

public void onEvent(com.github.shyiko.mysql.binlog.event.Event event)

Specified by:

onEvent in interface com.github.shyiko.mysql.binlog.BinaryLogClient.EventListener

consumeAll

public void consumeAll(long timeout,
                       TimeUnit unit)
                throws TimeoutException

Blocks for the specified amount of time, consuming (and discarding) all events.

Parameters:

timeout - the maximum amount of time that this method should block

unit - the time unit for timeout

Throws:

TimeoutException - if the waiting timed out before the expected number of events were received

consume

public void consume(int eventCount,
                    Predicate<com.github.shyiko.mysql.binlog.event.Event> condition)
             throws TimeoutException

Blocks until the listener has consume the specified number of matching events, blocking at most the default number of milliseconds. If this method has not reached the number of matching events and comes across events that do not satisfy the predicate, those events are consumed and ignored.

Parameters:

eventCount - the number of events

condition - the event-based predicate that signals a match; may not be null

Throws:

TimeoutException - if the waiting timed out before the expected number of events were received

consume

public void consume(int eventCount,
                    long timeoutInMillis,
                    Predicate<com.github.shyiko.mysql.binlog.event.Event> condition)
             throws TimeoutException

Blocks until the listener has consume the specified number of matching events, blocking at most the specified number of milliseconds. If this method has not reached the number of matching events and comes across events that do not satisfy the predicate, those events are consumed and ignored.

Parameters:

eventCount - the number of events

timeoutInMillis - the maximum amount of time in milliseconds that this method should block

condition - the event-based predicate that signals a match; may not be null

Throws:

TimeoutException - if the waiting timed out before the expected number of events were received

consume

public void consume(int eventCount,
                    com.github.shyiko.mysql.binlog.event.EventType type)
             throws TimeoutException

Blocks until the listener has seen the specified number of events with the given type, or until the default timeout has passed.

Parameters:

eventCount - the number of events

type - the type of event

Throws:

TimeoutException - if the waiting timed out before the expected number of events were received

consume

public void consume(int eventCount,
                    com.github.shyiko.mysql.binlog.event.EventType type,
                    long timeoutMillis)
             throws TimeoutException

Blocks until the listener has seen the specified number of events with the given type, or until the specified time has passed.

Parameters:

eventCount - the number of events

type - the type of event

timeoutMillis - the maximum amount of time in milliseconds that this method should block

Throws:

TimeoutException - if the waiting timed out before the expected number of events were received

consume

public void consume(int eventCount,
                    Class<? extends com.github.shyiko.mysql.binlog.event.EventData> eventDataClass)
             throws TimeoutException

Blocks until the listener has seen the specified number of events with the given type, or until the default timeout has passed.

Parameters:

eventCount - the number of events

eventDataClass - the EventData subclass

Throws:

TimeoutException - if the waiting timed out before the expected number of events were received

consume

public void consume(int eventCount,
                    Class<? extends com.github.shyiko.mysql.binlog.event.EventData> eventDataClass,
                    long timeoutMillis)
             throws TimeoutException

Blocks until the listener has seen the specified number of events with event data matching the specified class, or until the specified time has passed.

Parameters:

eventCount - the number of events

eventDataClass - the EventData subclass
