      Writes complete segments to the underlying sink, if one exists. Like BufferSink.flush(), but weaker. Use this to limit the memory held in the buffer to a single segment. Typically application code will not need to call this: it is only necessary when application code writes directly to this sink's buffer.

      public BufferSink emit() throws IOException
      Description copied from interface: BufferSink
      Writes all buffered data to the underlying sink, if one exists. Like BufferSink.flush(), but weaker. Call this before this buffered sink goes out of scope so that its data can reach its destination. 
      

   BufferedSink b0 = new Buffer();
   BufferedSink b1 = Okio.buffer(b0);
   BufferedSink b2 = Okio.buffer(b1);

   b2.writeUtf8("hello");

    • flush

      public void flush() throws IOException
      Description copied from interface: BufferSink
      Writes all buffered data to the underlying sink, if one exists. Then that sink is recursively flushed which pushes data as far as possible towards its ultimate destination. Typically that destination is a network socket or file. 
      

   BufferedSink b0 = new Buffer();
   BufferedSink b1 = Okio.buffer(b0);
   BufferedSink b2 = Okio.buffer(b1);

   b2.writeUtf8("hello");
   assertEquals(5, b2.buffer().size());
   assertEquals(0, b1.buffer().size());
   assertEquals(0, b0.buffer().size());

   assertEquals(0, b2.buffer().size());
   assertEquals(0, b1.buffer().size());
   assertEquals(5, b0.buffer().size());
      Specified by:
      flush in interface BufferSink
      Specified by:

    • close

      public void close()
      Description copied from interface: Sink
      Pushes all buffered bytes to their final destination and releases the resources held by this sink. It is an error to write a closed sink. It is safe to close a sink more than once.
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Channel
      Specified by:
      close in interface Closeable
      Specified by:
      close in interface Sink

      Description copied from interface: Sink
      Returns the timeout for this sink.
      Specified by:
      timeout in interface Sink
