Class JRValueStringUtils

java.lang.Object

net.sf.jasperreports.engine.util.JRValueStringUtils

public final class JRValueStringUtils
extends Object

Utility class used to serialize/deserialize value objects to/from String values.

Specific logic is used to convert to and from Strings values of the following types:

• java.lang.String
• java.lang.Character
• java.lang.Boolean
• java.lang.Byte
• java.lang.Short
• java.lang.Integer
• java.lang.Long
• java.lang.Float
• java.lang.Double
• java.math.BigInteger
• java.math.BigDecimal
• java.util.Date
• java.sql.Timestamp
• java.sql.Time

Object of other types are serialized and the resulting binary data is converted into a String using the BASE64 encoding.
