Class MemoryComputeKey<A>

java.lang.Object

org.apache.tinkerpop.gremlin.process.computer.MemoryComputeKey<A>

All Implemented Interfaces:

Serializable

public final class MemoryComputeKey<A>
extends Object
implements Serializable

A MemoryComputeKey specifies what keys will be used by a Memory during a GraphComputer computation. A MemoryComputeKey maintains a BinaryOperator which specifies how to reduce parallel values into a single value. A MemoryComputeKey can be broadcasted and as such, the workers will receive mutations to the Memory value. A MemoryComputeKey can be transient and thus, will not be accessible once the GraphComputer computation is complete.
