- readUtf8
  public String readUtf8() throws IOException
  
  Description copied from interface: BufferSource
  
  Removes all bytes from this, decodes them as UTF-8, and returns the string. Returns the empty string if this source is empty.
  Buffer buffer = new Buffer().writeUtf8("Uh uh uh!").writeByte(' ').writeUtf8("You didn't say the magic word!"); assertEquals("Uh uh uh! You didn't say the magic word!", buffer.readUtf8()); assertEquals(0, buffer.size()); assertEquals("", buffer.readUtf8()); assertEquals(0, buffer.size());

  Description copied from interface: BufferSource
  
  Removes all bytes from this, decodes them as charset, and returns the string.
  
  Specified by:
  
  readString in interface BufferSource
  
  Throws:
  
  IOException
- readString
  
  public String readString(long byteCount, Charset charset) throws IOException
  
  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:
  
  IOException
- readUtf8Line
  public String readUtf8Line() throws IOException
  
  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:
  
  IOException
- readUtf8LineStrict
  
  public String readUtf8LineStrict() throws IOException
  
  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:
  
  IOException
- readUtf8LineStrict
  public String readUtf8LineStrict(long limit) throws IOException
  
  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:
  
  IOException
- readUtf8CodePoint
  
  public int readUtf8CodePoint() throws IOException
  
  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).
  
  Specified by:
  
  readUtf8CodePoint in interface BufferSource
  
  Throws:
  
  IOException
- readShort
  public short readShort() throws IOException

  public boolean rangeEquals(long offset, ByteString bytes) throws IOException
  
  Description copied from interface: BufferSource
  
  Returns true if the bytes at offset in this source equal bytes. This expands the buffer as necessary until a byte does not match, all bytes are matched, or if the stream is exhausted before enough bytes could determine a match.
  ByteString simonSays = ByteString.encodeUtf8("Simon says:"); Buffer standOnOneLeg = new Buffer().writeUtf8("Simon says: Stand on one leg."); assertTrue(standOnOneLeg.rangeEquals(0, simonSays)); Buffer payMeMoney = new Buffer().writeUtf8("Pay me $1,000,000."); assertFalse(payMeMoney.rangeEquals(0, simonSays));

- rangeEquals
  
  public boolean rangeEquals(long offset, ByteString bytes, int bytesOffset, int byteCount) throws IOException
  
  Description copied from interface: BufferSource
  
  Returns true if byteCount bytes at offset in this source equal bytes at bytesOffset. This expands the buffer as necessary until a byte does not match, all bytes are matched, or if the stream is exhausted before enough bytes could determine a match.

- peek
  public BufferSource peek()
  
  Description copied from interface: BufferSource
  
  Returns a new BufferedSource that can read data from this BufferedSource without consuming it. The returned source becomes invalid once this source is next read or closed.
  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"

- inputStream
  
  public InputStream inputStream()
  
  Description copied from interface: BufferSource
  
  Returns an input stream that reads from this source.

- isOpen
  
  public boolean isOpen()
  
  Specified by:

- close
  
  public void close() throws IOException
  
  Description copied from interface: Source
  
  关闭此源并释放此源持有的资源. 读取闭源是一个错误。多次关闭源是安全的.

- timeout
