Class MetricFilterInputStream

java.lang.Object

java.io.InputStream

java.io.FilterInputStream

All Implemented Interfaces:

com.amazonaws.internal.MetricAware, Closeable, AutoCloseable

public class MetricFilterInputStream
extends com.amazonaws.internal.SdkFilterInputStream

Used to capture the input stream throughput metrics, but excluding the FilterInputStream.read() API.

Note this class is only relevant when metric is enabled. Otherwise it should not even be involved in the call stack to minimize runtime overhead.
