Method

T	clone(T orig, Configuration conf) Make a copy of a writable object using serialization to a buffer.
void	cloneInto(Writable dst, Writable src) Make a copy of the writable object using serialization to a buffer
int	decodeVIntSize(byte value) Parse the first byte of a vint/vlong to determine the number of bytes
int	getVIntSize(long i) Get the encoded length if an integer is stored in a variable-length format
boolean	isNegativeVInt(byte value) Given the first byte of a vint/vlong, determine the sign
byte[]	readCompressedByteArray(DataInput in)
String	readCompressedString(DataInput in)

String	readString(DataInput in)
String[]	readStringArray(DataInput in)
String	readStringSafely(DataInput in, int maxLength) Read a string, but check it for sanity.
int	readVInt(DataInput stream) Reads a zero-compressed encoded integer from input stream and returns it.
long	readVLong(DataInput stream) Reads a zero-compressed encoded long from input stream and returns it.
void	skipFully(DataInput in, int len) Skip len number of bytes in input streamin
byte[]	toByteArray(Writable... writables) Convert writables to a byte array
int	writeCompressedByteArray(DataOutput out, byte[] bytes)
void	writeCompressedStringArray(DataOutput out, String[] s)
void	writeEnum(DataOutput out, Enum enumVal) writes String value of enum to DataOutput.
void	writeString(DataOutput out, String s)
void	writeStringArray(DataOutput out, String[] s)
void	writeVInt(DataOutput stream, int i) Serializes an integer to a binary stream with zero-compressed encoding.
void	writeVLong(DataOutput stream, long i) Serializes a long to a binary stream with zero-compressed encoding.
