Class VectorHashKeyWrapperBase

java.lang.Object

org.apache.hadoop.hive.ql.exec.KeyWrapper

org.apache.hadoop.hive.ql.exec.vector.wrapper.VectorHashKeyWrapperBase

Direct Known Subclasses:

VectorHashKeyWrapperEmpty, VectorHashKeyWrapperGeneral, VectorHashKeyWrapperSingleBase, VectorHashKeyWrapperTwoBase

public abstract class VectorHashKeyWrapperBase
extends KeyWrapper

A hash map key wrapper for vectorized processing. It stores the key values as primitives in arrays for each supported primitive type. This works in conjunction with VectorHashKeyWrapperBatch to hash vectorized processing units (batches).
