- - ### Constructor Detail

    - #### CountingInputStream

          public CountingInputStream(java.io.InputStream in)

  - ### Method Detail

    - #### read

          public int read(byte[] buffer,
                 int offset,
                 int length)
                   throws java.io.IOException

      Note: we must not override the read(byte[] buffer) method! This would lead in counting twice.
      Overrides:
        `read` in class `java.io.FilterInputStream`
      Throws:
        `java.io.IOException`

    - #### read

          public int read()
                   throws java.io.IOException

      Overrides:
        `read` in class `java.io.FilterInputStream`
      Throws:
        `java.io.IOException`

    - #### skip

          public long skip(long length)
                    throws java.io.IOException

      Overrides:
        `skip` in class `java.io.FilterInputStream`
      Throws:
        `java.io.IOException`

    - #### getByteCount

          public long getByteCount()

    - #### resetByteCount
