Class StringMapCodec

java.lang.Object

com.enterprisemath.utils.StringMapCodec

public class StringMapCodec
extends Object

Utility class for encoding / decoding objects to / from the string maps. Transformations are supported for the following data types:

• Null
• Primitives (raw and boxed) - Boolean, Byte, Integer, Long, Float, Double
• Strings
• Collections - lists, sets and maps without specified implementation
• Enumerations - stored by name
• Date - stored in 'yyyy/MM/dd HH:mm:ss.SSS' format without time zone
• Objects with builder class - builder class must be public static inner class named Builder and has to contain method build. Properties with the same name as in the builder class are serialized. During deserialization they are injected by the setter method (e.g. setProperty(T x)...) or directly if there is no setter method. Properties might be sorted map or sorted set. In such case the sorting is expected to be natural and some standard implementation is used (e.g. TreeSet and TreeMap).
