Class IgniteComputeHandler

java.lang.Object

org.apache.ignite.internal.IgniteComputeHandler

public class IgniteComputeHandler
extends Object

Represents a general facade that delegates Ignite compute requests to GridTaskProcessor and GridClosureProcessor internal processors. It also provides a built-in mechanism for accumulating execution options that are automatically applied to computations.
