- All Implemented Interfaces:
    Closeable, AutoCloseable

      public class EofSensorInputStream
      extends InputStream

  A stream wrapper that triggers actions on `close()` and EOF. Primarily used to auto-release an underlying managed connection when the response body is consumed or no longer needed.

- - ### Constructor Detail

    - #### EofSensorInputStream

          public EofSensorInputStream(InputStream in,
                                      EofSensorWatcher watcher)

      Creates a new EOF sensor. If no watcher is passed, the underlying stream will simply be closed when EOF is detected or `close` is called. Otherwise, the watcher decides whether the underlying stream should be closed before detaching from it.
      Parameters:
        `in` - the wrapped stream
        `watcher` - the watcher for events, or `null` for auto-close behavior without notification

  - ### Method Detail

    - #### read

          public int read()
                   throws IOException

      Specified by:
        `read` in class `InputStream`
      Throws:
        `IOException`

    - #### read

          public int read(byte[] b,
                          int off,
                          int len)
                   throws IOException

      Overrides:
        `read` in class `InputStream`
      Throws:
        `IOException`

    - #### read

          public int read(byte[] b)
                   throws IOException

      Overrides:
        `read` in class `InputStream`
      Throws:
        `IOException`

    - #### available

          public int available()
                        throws IOException

      Overrides:
        `available` in class `InputStream`
      Throws:
        `IOException`

    - #### close

          public void close()
                     throws IOException

      Specified by:
        `close` in interface `Closeable`
      Specified by:
        `close` in interface `AutoCloseable`
      Overrides:
        `close` in class `InputStream`
      Throws:
        `IOException`

    - #### abort

          public void abort()
                     throws IOException

      Aborts this stream. This is a special version of `close()` which prevents re-use of the underlying connection, if any. Calling this method indicates that there should be no attempt to read until the end of the stream.
      Throws:
        `IOException` - in case of an IO problem on closing the underlying stream
