Method Detail

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 classDataOutput
- See Also:
DataInput.readByte()
-
writeBytes
public void writeBytes(byte[] b, int off, int len)
Description copied from class:DataOutput
Writes an array of bytes.- Specified by:
writeBytes
in classDataOutput
- Parameters:
b
- the bytes to writeoff
- the offset in the byte arraylen
- the number of bytes to write- See Also:
DataInput.readBytes(byte[],int,int)
-
writeString
public void writeString(String string) throws IOException
Description copied from class:DataOutput
Writes a string.Writes strings as UTF-8 encoded bytes. First the length, in bytes, is written as a
VInt
, followed by the bytes.- Overrides:
writeString
in classDataOutput
- Throws:
IOException
- See Also:
DataInput.readString()

getBytes
