reset

public void reset(byte[] bytes,
         int offset,
         int len)

getPosition

public int getPosition()

writeByte

public void writeByte(byte b)

Description copied from class: DataOutput

Writes a single byte.

The most primitive data type is an eight-bit byte. Files are accessed as sequences of bytes. All other data types are defined as sequences of bytes, so file formats are byte-order independent.

Specified by:

writeByte in class DataOutput

See Also:

DataInput.readByte()

writeBytes

public void writeBytes(byte[] b,
              int offset,
              int length)

Description copied from class: DataOutput

Writes an array of bytes.

Specified by:

writeBytes in class DataOutput

Parameters:

b - the bytes to write

offset - the offset in the byte array

length - the number of bytes to write
