## Class BufferingOutputStream

- java.lang.Object
- - java.io.OutputStream
  - - org.bouncycastle.util.io.BufferingOutputStream

- All Implemented Interfaces:
    `java.io.Closeable`, `java.io.Flushable`, `java.lang.AutoCloseable`

      public class BufferingOutputStream
      extends java.io.OutputStream

  An output stream that buffers data to be feed into an encapsulated output stream.

  The stream zeroes out the internal buffer on each flush.
