Examples of com.amazonaws.event.ProgressListenerChain

com.amazonaws.event.ProgressListenerChain
An implementation of ProgressListener interface that delegates progressChanged callback to multiple listeners. It also takes an optional ProgressEventFilter to filter incoming events before passing them to the listeners.
This class could be used for both Amazon S3 and Amazon Glacier clients. The legacy Amazon S3 progress listener chain com.amazonaws.services.s3.transfer.internal.ProgressListenerChain has been deprecated in favor of this new class.

        ProgressListenerChain listenerChain = new ProgressListenerChain(new TransferProgressUpdatingListener(
                transferProgress), getObjectRequest.getGeneralProgressListener());
        getObjectRequest.setGeneralProgressListener(listenerChain);
        final ObjectMetadata objectMetadata = s3.getObjectMetadata(getObjectRequest.getBucketName(), getObjectRequest.getKey());


        final StartDownloadLock startDownloadLock = new StartDownloadLock();
