Examples of eu.stratosphere.core.memory.DataOutputView

eu.stratosphere.core.memory.DataOutputView
This interface defines a view over some memory that can be used to sequentially write contents to the memory. The view is typically backed by one or more {@link eu.stratosphere.core.memory.MemorySegment}.
