getBuffer in interface WriteBuffer.BufferOutputpublic void writeSafeUTF(String s) throws IOException
The binary format for a Safe UTF value is a "packed int" for the binary length followed by the UTF-encoded byte stream. The length is either -1 (indicating a null String) or in the range 0 .. Integer.MAX_VALUE (inclusive). The UTF-encoded portion uses a format identical to DataOutput.

public void writePackedInt(int n)
throws IOException
The format differs from DataOutput in that DataOutput always uses a fixed-length 4-byte Big Endian binary format for int values. The "packed" format includes a sign bit (0x40) and a continuation bit (0x80) in the first byte, followed by the least 6 significant bits of the int value. Subsequent bytes (each appearing only if the previous byte had its continuation bit set) include a continuation bit (0x80) and the next least 7 significant bits of the int value. In this way, a 32-bit value is encoded into 1-5 bytes, depending on the magnitude of the int value being encoded.

The format differs from DataOutput in that DataOutput always uses a fixed-length 8-byte Big Endian binary format for long values. The "packed" format includes a sign bit (0x40) and a continuation bit (0x80) in the first byte, followed by the least 6 significant bits of the long value. Subsequent bytes (each appearing only if the previous byte had its continuation bit set) include a continuation bit (0x80) and the next least 7 significant bits of the long value. In this way, a 64-bit value is encoded into 1-10 bytes, depending on the magnitude of the long value being encoded.
