Field Detail

table

public static final jobmatch.data.RDBTable table

static final data members name the table and columns for this DO. By using these members with an instance of the QueryBuilder class, an application can perform straight SQL queries while retaining compile-time checking of table and column usage. Example: List the Cities containing Persons named Bob: Using straight SQL with QueryBuilder: Pro: code runs faster because you create fewer objects Con: code is less clear Vector fields = new Vector(); fields.addElement( AddressDO.City ); QueryBuilder qb = new QueryBuilder( fields ); qb.addWhere( PersonDO.FirstName, "Bob" ); qb.addWhere( PersonDO.PrimaryKey, AddressDO.Person ); RDBRow row; while ( null != ( row = qb.getNextRow() ) ) { String city = row.get( AddressDO.City ).getString(); } Using Query/DO classes: Pro: code is (often) clearer Con: code runs slower because you create more objects PersonQuery pq = new PersonQuery(); pq.setQueryFirstName( "Bob" ); PersonDO[] bobs = pq.getDOArray(); for ( int i = 0; i < bobs.length; i++ ) { AddressQuery aq = new AddressQuery(); aq.setQueryPerson( bobs[i] ); AddressDO addr = aq.getNextDO(); String city = addr.getCity(); }

Constructor Detail

CVSectionDO

protected CVSectionDO(boolean is_view)
               throws jobmatch.data.ObjectIdException,
                      jobmatch.data.DatabaseManagerException

Protected constructor. Only derived classes should call it.

Throws:

jobmatch.data.DatabaseManagerException - If a connection to the database cannot be established, etc.

com.lutris.appserver.server.sql.ObjectIdException - If an object id can't be allocated for this object.

CVSectionDO

protected CVSectionDO()
               throws jobmatch.data.ObjectIdException,
                      jobmatch.data.DatabaseManagerException

Protected constructor. Only derived classes should call it.

Throws:

jobmatch.data.DatabaseManagerException - If a connection to the database cannot be established, etc.

com.lutris.appserver.server.sql.ObjectIdException - If an object id can't be allocated for this object.

CVSectionDO

protected CVSectionDO(jobmatch.data.ObjectId id)
               throws SQLException,
                      jobmatch.data.ObjectIdException,
                      jobmatch.data.DataObjectException,
                      jobmatch.data.DatabaseManagerException

Protected constructor used by createExisting(ObjectId) above. Historical note (delete at will): Formerly, createExisting(ObjectId) invoked the no-args GenericDO ctor, which allocated a new ObjectId. Then, createExisting(ObjectId) would call setOId(id), discarding the newly allocated ObjectId; this resulted in an ObjectId "leak" (needless consumption of oid's.)

Parameters:

id - The ObjectId for the object.

Throws:

jobmatch.data.DataObjectException - If the object is not found in the database.

com.lutris.appserver.server.sql.ObjectIdException - If an object id can't be allocated for this object.

jobmatch.data.DatabaseManagerException - If a connection to the database cannot be established, etc.

SQLException - Should never see this exception since GenericDO.ctor(ObjectId) never accesses the database.

CVSectionDO

protected CVSectionDO(ResultSet rs)
               throws SQLException,
                      jobmatch.data.ObjectIdException,
                      jobmatch.data.DataObjectException,
                      jobmatch.data.DatabaseManagerException

Protected constructor.

Parameters:

rs - Result set from which to obtain product data.

Throws:

jobmatch.data.DataObjectException - If the object is not found in the database.

com.lutris.appserver.server.sql.ObjectIdException - If an object id can't be allocated for this object.

jobmatch.data.DatabaseManagerException - If a connection to the database cannot be established, etc.

SQLException - If the database rejects the SQL generated to retrieve data for this object, or if the table contains a bad foreign key, etc.
