CompactDataOutput
public CompactDataOutput(OutputStream out)
- Creates a new
CompactDataOutput
instance that writes data to the
specified underlying output stream
- Parameters:
out
- underlying output stream
writeVarInt
public void writeVarInt(int value)
throws IOException
- Writes a variable length representation of an integer value that reduces
the number of written bytes for small positive values. Depends on the
given value 1 to 5 bytes will be written to the underlying stream.
- Parameters:
value
- value to write
- Throws:
IOException
writePackedBoolean
public void writePackedBoolean(boolean value)
throws IOException
- Writes a boolean value. Internally a sequence of boolean values is packed
into single bits. After the last boolean value has been written
finishPackedBoolean()
has to be called.
- Parameters:
value
- boolean value
- Throws:
IOException
finishPackedBoolean
public void finishPackedBoolean()
throws IOException
- Finalizes the output of a sequence of packed boolean values.
- Throws:
IOException
