Class SqlTypeMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

com.actian.vw.connector.common.SqlTypeMap<K,V>

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>

public class SqlTypeMap<K,V>
extends HashMap<K,V>

Using java.utils.HashMap to store primitive data types such as int can be unsafe because auto-unboxing a null value in the map can cause a NPE. SqlTypeMap is meant to be safer because it provides validation for arguments and fails fast with informative messages if invalid arguments are given.
