Class JAXBTypesafeEnumConverter

java.lang.Object

org.eclipse.persistence.jaxb.JAXBTypesafeEnumConverter

public class JAXBTypesafeEnumConverter
extends java.lang.Object

Purpose: JAXBTypesafeEnumConverter is used to allow mapping to type safe enums according to the JAXB 1.0 spec. Object values are not modified by the converter when writing data values. Data values are read in and the "fromString" method on the enumeration class is invoked with the data value as a parameter. The return value from the "fromString" method will be an instance of the enum class specified on the mapping.
