## Class MemoryComputeKey<A>

- java.lang.Object
- - org.apache.tinkerpop.gremlin.process.computer.MemoryComputeKey<A>

- All Implemented Interfaces:
    Serializable, Cloneable

      public final class MemoryComputeKey<A>
      extends Object
      implements Serializable, Cloneable

  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.
