List of writeGamma() Examples

Examples of writeGamma()

it.unimi.dsi.io.InputBitStream.writeGamma()
it.unimi.dsi.io.OutputBitStream.writeGamma()
ivory.core.compression.BitOutputStream.writeGamma()
Writes an integer x into the stream using gamma encoding. This method is not failsafe, it doesn't check if the argument is 0 or negative. @param x the int number to write @return the number of bits written @throws IOException if an I/O error occurs.
