Package com.arcadedb.query.sql.executor

Class CheckIsEdgeTypeStep

java.lang.Object

com.arcadedb.query.sql.executor.AbstractExecutionStep

com.arcadedb.query.sql.executor.CheckIsEdgeTypeStep

All Implemented Interfaces:

ExecutionStep, ExecutionStepInternal

public class CheckIsEdgeTypeStep
extends AbstractExecutionStep

This step is used just as a gate check for classes (eg. for CREATE EDGE to make sure that the passed type is an edge type).
