Class CastStringToFloat

java.lang.Object

org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression

org.apache.hadoop.hive.ql.exec.vector.expressions.CastStringToDouble

org.apache.hadoop.hive.ql.exec.vector.expressions.CastStringToFloat

All Implemented Interfaces:

Serializable

public class CastStringToFloat
extends CastStringToDouble

Cast a string to a double. If other functions besides cast need to take a string in and produce a long, you can subclass this class or convert it to a superclass, and implement different "func()" methods for each operation.
