public class VectorHashKeyWrapperGeneral
extends VectorHashKeyWrapperBase

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).
