Class ConvertToResultInternalStep

java.lang.Object

com.orientechnologies.orient.core.sql.executor.AbstractExecutionStep

com.orientechnologies.orient.core.sql.executor.ConvertToResultInternalStep

All Implemented Interfaces:

OExecutionStep, OExecutionStepInternal

public class ConvertToResultInternalStep
extends AbstractExecutionStep
