com.esotericsoftware.kryo.io.Output
An OutputStream that buffers data in a byte array and optionally flushes to another OutputStream. Utility methods are provided for efficiently writing primitive types and strings. Encoding of integers: BIG_ENDIAN is used for storing fixed native size integer values LITTLE_ENDIAN is used for a variable length encoding of integer values @author Nathan Sweet
