java.lang.Object

org.aksw.limes.core.execution.engine.ExecutionEngine

org.aksw.limes.core.execution.engine.ParallelExecutionEngine

All Implemented Interfaces:

IExecutionEngine

public class ParallelExecutionEngine
extends ExecutionEngine

Implements the default execution engine class. The idea is that the engine gets as input a link specification and a planner type, executes the independent parts of the plan returned from the planner in parallel and returns a MemoryMemoryMapping.
