Examples of UnsafeMemorySegment

eu.stratosphere.nephele.services.memorymanager.UnsafeMemorySegment
This class represents a piece of memory allocated from the memory manager. The segment is backed by a byte array and features random put and get methods for the basic types that are stored in a byte-wise fashion in the memory.
