      com.planetj.servlet.filter.compression.StatsInputStream

All Implemented Interfaces:

java.io.Closeable

final class StatsInputStream
extends java.io.InputStream

An InputStream that decorates another InputStream and notes when bytes are read from the stream. Callers create an instance of StatsInputStream with an instance of StatsInputStream.StatsCallback, which receives notification of reads. This information might be used to tally the number of bytes read from a stream.
