  public Buffer buffer()
  
  Description copied from interface: BufferSink
  
  Returns this sink's internal buffer.
  
  Specified by:
  
  buffer in interface BufferSink
- getBuffer
  
  public Buffer getBuffer()
  
  Description copied from interface: BufferSource
  
  This source's internal buffer.
  
  Specified by:
  
  getBuffer in interface BufferSource
- outputStream
  
  public OutputStream outputStream()
  
  Description copied from interface: BufferSink
  
  Returns an output stream that writes to this sink.
  
  Specified by:
  
  outputStream in interface BufferSink
- emitCompleteSegments
  public Buffer emitCompleteSegments()
  
  Description copied from interface: BufferSink
  
  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.
  BufferedSink b0 = new Buffer(); BufferedSink b1 = Okio.buffer(b0); BufferedSink b2 = Okio.buffer(b1); b2.buffer().write(new byte[20_000]); assertEquals(20_000, b2.buffer().size()); assertEquals(0, b1.buffer().size()); assertEquals(0, b0.buffer().size()); b2.emitCompleteSegments(); assertEquals(3_616, b2.buffer().size()); assertEquals(0, b1.buffer().size()); assertEquals(16_384, b0.buffer().size()); // This example assumes 8192 byte segments.
  
  Specified by:
  
  emitCompleteSegments in interface BufferSink
- emit
  public BufferSink emit()
  
  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"); assertEquals(5, b2.buffer().size()); assertEquals(0, b1.buffer().size()); assertEquals(0, b0.buffer().size()); b2.emit(); assertEquals(0, b2.buffer().size()); assertEquals(5, b1.buffer().size()); assertEquals(0, b0.buffer().size()); b1.emit(); assertEquals(0, b2.buffer().size()); assertEquals(0, b1.buffer().size()); assertEquals(5, b0.buffer().size());

  Specified by:
  
  request in interface BufferSource
- peek

  For example, we can use peek() to lookahead and read the same data multiple times.
  Buffer buffer = new Buffer(); buffer.writeUtf8("abcdefghi"); buffer.readUtf8(3) // returns "abc", buffer contains "defghi" BufferedSource peek = buffer.peek(); peek.readUtf8(3); // returns "def", buffer contains "defghi" peek.readUtf8(3); // returns "ghi", buffer contains "defghi" buffer.readUtf8(3); // returns "def", buffer contains "ghi"

  public String readString(long byteCount, Charset charset) throws EOFException
  
  Description copied from interface: BufferSource
  
  Removes byteCount bytes from this, decodes them as charset, and returns the string.
  
  Specified by:
  
  readString in interface BufferSource
  
  Throws:
  
  EOFException
- readUtf8Line
  public String readUtf8Line() throws EOFException
  
  Description copied from interface: BufferSource
  
  Removes and returns characters up to but not including the next line break. A line break is either "\n" or "\r\n"; these characters are not included in the result.
  Buffer buffer = new Buffer().writeUtf8("I'm a hacker!\n").writeUtf8("That's what I said: you're a nerd.\n") .writeUtf8("I prefer to be called a hacker!\n"); assertEquals(81, buffer.size()); assertEquals("I'm a hacker!", buffer.readUtf8Line()); assertEquals(67, buffer.size()); assertEquals("That's what I said: you're a nerd.", buffer.readUtf8Line()); assertEquals(32, buffer.size()); assertEquals("I prefer to be called a hacker!", buffer.readUtf8Line()); assertEquals(0, buffer.size()); assertEquals(null, buffer.readUtf8Line()); assertEquals(0, buffer.size());
  
  On the end of the stream this method returns null, just like BufferedReader. If the source doesn't end with a line break then an implicit line break is assumed. Null is returned once the source is exhausted. Use this for human-generated data, where a trailing line break is optional.
  
  Specified by:
  
  readUtf8Line in interface BufferSource
  
  Throws:
  
  EOFException
- readUtf8LineStrict
  
  public String readUtf8LineStrict() throws EOFException
  
  Description copied from interface: BufferSource
  
  Removes and returns characters up to but not including the next line break. A line break is either "\n" or "\r\n"; these characters are not included in the result.
  On the end of the stream this method throws. Every call must consume either '\r\n' or '\n'. If these characters are absent in the stream, an EOFException is thrown. Use this for machine-generated data where a missing line break implies truncated input.
  
  Specified by:
  
  readUtf8LineStrict in interface BufferSource
  
  Throws:
  
  EOFException
- readUtf8LineStrict
  public String readUtf8LineStrict(long limit) throws EOFException
  
  Description copied from interface: BufferSource
  
  Like BufferSource.readUtf8LineStrict(), except this allows the caller to specify the longest allowed match. Use this to protect against streams that may not include "\n" or "\r\n".
  The returned string will have at most limit UTF-8 bytes, and the maximum number of bytes scanned is limit + 2. If limit == 0 this will always throw an EOFException because no bytes will be scanned.
  This method is safe. No bytes are discarded if the match fails, and the caller is free to try another match:
  Buffer buffer = new Buffer(); buffer.writeUtf8("12345\r\n"); // This will throw! There must be \r\n or \n at the limit or before it. buffer.readUtf8LineStrict(4); // No bytes have been consumed so the caller can retry. assertEquals("12345", buffer.readUtf8LineStrict(5));
  
  Specified by:
  
  readUtf8LineStrict in interface BufferSource
  
  Throws:
  
  EOFException

  Throws:
  
  EOFException
- readUtf8CodePoint
  
  public int readUtf8CodePoint() throws EOFException
  
  Description copied from interface: BufferSource
  
  Removes and returns a single UTF-8 code point, reading between 1 and 4 bytes as necessary.
  If this source is exhausted before a complete code point can be read, this throws an EOFException and consumes no input.
  If this source doesn't start with a properly-encoded UTF-8 code point, this method will remove 1 or more non-UTF-8 bytes and return the replacement character (U+FFFD). This covers encoding problems (the input is not properly-encoded UTF-8), characters out of range (beyond the 0x10ffff limit of Unicode), code points for UTF-16 surrogates (U+d800..U+dfff) and overlong encodings (such as 0xc080 for the NUL character in modified UTF-8).
