Class VectorAccessibleUtilities

java.lang.Object

org.apache.drill.exec.record.VectorAccessibleUtilities

public class VectorAccessibleUtilities
extends Object

VectorAccessible is an interface. Yet, several operations are done on VectorAccessible over and over gain. While Java 8 allows static methods on an interface, Drill uses Java 7, which does not. This class is a placeholder for common VectorAccessible methods that can migrate into the interface when Drill upgrades to Java 8.
