Method Detail

handle

public void handle(boolean success,
                   String message,
                   Throwable error)

Specified by:

handle in interface io.debezium.engine.DebeziumEngine.CompletionCallback

await

public void await()
           throws InterruptedException

Causes the current thread to wait until the completion occurs or until the thread is interrupted.

This method returns immediately if the connector has completed already.

Throws:

InterruptedException - if the current thread is interrupted while waiting

await

public boolean await(long timeout,
                     TimeUnit unit)
              throws InterruptedException

Causes the current thread to wait until the completion occurs, unless the thread is interrupted, or the specified waiting time elapses.

This method returns immediately if the connector has completed already.

Parameters:

timeout - the maximum time to wait

unit - the time unit of the timeout argument

Returns:

true if the completion was received, or false if the waiting time elapsed before the completion was received.

Throws:

InterruptedException - if the current thread is interrupted while waiting

hasCompleted

public boolean hasCompleted()

Determine if the connector has completed.

Returns:

true if the connector has completed, or false if the connector is still running and this callback has not yet been notified

success

public boolean success()

Get whether the connector completed normally.

Returns:

true if the connector completed normally, or false if the connector produced an error that prevented startup or premature termination (or the connector has not yet completed)

message

public String message()

Get the completion message.

Returns:

the completion message, or null if the connector has not yet completed

error

public Throwable error()

Get the completion error, if there is one.

Returns:

the completion error, or null if there is no error or connector has not yet completed

hasError

public boolean hasError()

Determine if there is a completion error.

Returns:

true if there is a completion error, or false if there is no error or the connector has not yet completed
