java.lang.Object
  org.apache.ojb.broker.accesslayer.conversions.Object2Base64StringFieldConversion

All Implemented Interfaces:

Serializable, FieldConversion

public class Object2Base64StringFieldConversion
extends Object
implements FieldConversion

this implementation of the FieldConversion interface converts between java.lang.Objects values and char[] values in the rdbms. This conversion is useful to store serialized objects in database columns. For an example have a look at the mapping of org.apache.ojb.odmg.collections.DlistEntry.
