Package org.apache.flink.runtime.io.network.buffer

Class FullyFilledBuffer

java.lang.Object

org.apache.flink.runtime.io.network.buffer.AbstractCompositeBuffer

org.apache.flink.runtime.io.network.buffer.FullyFilledBuffer

All Implemented Interfaces:

Buffer

public class FullyFilledBuffer
extends AbstractCompositeBuffer

An implementation of Buffer represents a fully filled buffer which contains multiple partial buffers for network data communication.

All partial must have the same data type and compression status. And they are originate from different write buffers but are combined to minimize network overhead.
