Class MultiTypeWrapper

java.lang.Object
tenapull.data.persistence.MultiTypeWrapper
public final class MultiTypeWrapper
extends java.lang.Object
Used to represent a field which may have multiple JSON primitive data types. When entering into the DB, a varchar(255) field is used where the first character represents the primary data type and the remaining characters represent the value. The "primary type" refers to the type used -- e.g. an AtomicInteger may be grouped with an Integer, etc
