          org.apache.ojb.broker.metadata.FieldTypeClasses.ClobFieldType

All Implemented Interfaces:

FieldType, java.io.Serializable

Enclosing class:

org.apache.ojb.broker.metadata.FieldTypeClasses

public static class FieldTypeClasses.ClobFieldType

extends org.apache.ojb.broker.metadata.FieldTypeClasses.ImmutableFieldType

Clob fields are logical pointer to DB, so for OJB it's immutable
