Examples of org.jpox.store.rdbms.typeinfo.TypeInfo

org.jpox.store.rdbms.typeinfo.TypeInfo
Represents the metadata of a specific JDBC data type. This class is basically a data structure that makes accessing the JDBC type metadata easier. Each of the columns of information returned by {@link java.sql.DatabaseMetaData#getTypeInfo()} is represented by a public field in this class.
Subclasses of TypeInfo can be created on a per-DBMS basis to supply missing metadata or correct faulty metadata obtained from that DBMS's JDBC driver(s).
