bufferSize - The buffer size to use

Returns:

A buffered input stream

createProgressTrackingStream

public static InputStream createProgressTrackingStream(InputStream inputStream,
 long totalSize,
 StreamingProgressListener listener)

Creates a progress-tracking input stream that reports progress at regular intervals.

Parameters:

inputStream - The input stream to wrap

totalSize - The total size of the stream in bytes (or -1 if unknown)

listener - The progress listener to notify

Returns:

A progress-tracking input stream

createProgressTrackingStream

public static InputStream createProgressTrackingStream(InputStream inputStream,
 long totalSize,
 StreamingProgressListener listener,
 long progressInterval)

Creates a progress-tracking input stream with a custom progress interval.

Parameters:

inputStream - The input stream to wrap

totalSize - The total size of the stream in bytes (or -1 if unknown)

listener - The progress listener to notify

progressInterval - The interval in bytes at which to report progress

Returns:

A progress-tracking input stream

createEnhancedStream

public static InputStream createEnhancedStream(InputStream inputStream,
 long totalSize,
 StreamingProgressListener listener)

Creates a combined buffered and progress-tracking stream.

Parameters:
