Class LoggingTransferListener

java.lang.Object

software.amazon.awssdk.transfer.s3.progress.LoggingTransferListener

All Implemented Interfaces:

TransferListener

public final class LoggingTransferListener
extends Object
implements TransferListener

An example implementation of TransferListener that logs a progress bar at the INFO level. This implementation effectively rate-limits how frequently updates are logged by only logging when a new "tick" advances in the progress bar. By default, the progress bar has ticks, meaning an update is only logged, at most, once every 5%.

public static LoggingTransferListener create(int maxTicks)

Create an instance of LoggingTransferListener with a custom maxTicks value.

Parameters:

maxTicks - the number of ticks in the logged progress bar

create

public static LoggingTransferListener create()

Create an instance of LoggingTransferListener with the default configuration.

transferInitiated

public void transferInitiated(TransferListener.Context.TransferInitiated context)

Description copied from interface: TransferListener

A new transfer has been initiated. This method is called exactly once per transfer.

Available context attributes:

1. TransferListener.Context.TransferInitiated.request()
2. TransferListener.Context.TransferInitiated.progressSnapshot()

Specified by:

transferInitiated in interface TransferListener

bytesTransferred

public void bytesTransferred(TransferListener.Context.BytesTransferred context)

Description copied from interface: TransferListener

Additional bytes have been submitted or received. This method may be called many times per transfer, depending on the transfer size and I/O buffer sizes.

Available context attributes:

1. TransferListener.Context.TransferInitiated.request()
2. TransferListener.Context.TransferInitiated.progressSnapshot()

Specified by:

bytesTransferred in interface TransferListener

transferComplete

public void transferComplete(TransferListener.Context.TransferComplete context)

Description copied from interface: TransferListener

The transfer has completed successfully. This method is called exactly once for a successful transfer.

Available context attributes:

1. TransferListener.Context.TransferInitiated.request()
2. TransferListener.Context.TransferInitiated.progressSnapshot()
3. TransferListener.Context.TransferComplete.completedTransfer()

Specified by:

transferComplete in interface TransferListener

transferFailed

public void transferFailed(TransferListener.Context.TransferFailed context)

Description copied from interface: TransferListener

The transfer failed. This method is called exactly once for a failed transfer.

Available context attributes:

1. TransferListener.Context.TransferInitiated.request()
2. TransferListener.Context.TransferInitiated.progressSnapshot()
3. TransferListener.Context.TransferFailed.exception()

Specified by:

transferFailed in interface TransferListener
