CompactDataOutput

public CompactDataOutput(java.io.OutputStream out)

Creates a new CompactDataOutput instance that writes data to the specified underlying output stream

Parameters:

out - underlying output stream

Method Detail

writeVarInt

public void writeVarInt(int value)
                 throws java.io.IOException

Writes a variable length representation of an integer value that reduces the number of written bytes for small positive values. Depending on the given value 1 to 5 bytes will be written to the underlying stream.

Parameters:

value - value to write

Throws:

java.io.IOException - if thrown by the underlying stream

writeBooleanArray

public void writeBooleanArray(boolean[] value)
                       throws java.io.IOException

Writes a boolean array. Internally a sequence of boolean values is packed into single bits.

Parameters:

value - boolean array

Throws:

java.io.IOException - if thrown by the underlying stream
