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:DataOutputWrites 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.
