Class MetricFilterInputStream

java.lang.Object
  java.io.InputStream
      java.io.FilterInputStream
          com.amazonaws.internal.SdkFilterInputStream
              com.amazonaws.metrics.MetricFilterInputStream

All Implemented Interfaces:

com.amazonaws.internal.MetricAware, Closeable

public class MetricFilterInputStream
extends com.amazonaws.internal.SdkFilterInputStream

Used to capture the input stream throughput metrics, but excluding the SdkFilterInputStream.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.
