Method Detail

reset

public void reset(byte[] bytes)

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
See Also:
DataInput.readBytes(byte[],int,int)
