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

SchooltypeDO

protected SchooltypeDO(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.

SchooltypeDO

protected SchooltypeDO()
                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.

SchooltypeDO

protected SchooltypeDO(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.

SchooltypeDO

protected SchooltypeDO(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.

createVirgin

public static SchooltypeDO createVirgin()
                                 throws jobmatch.data.DatabaseManagerException,
                                        jobmatch.data.ObjectIdException

createVirgin() Creates a DO that has no ObjectId or data. Such a DO is used to insert a new database entry after its data has been set.

Throws:

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.

createExisting

public static SchooltypeDO createExisting(BigDecimal bd)
                                   throws SQLException,
                                          jobmatch.data.ObjectIdException,
                                          jobmatch.data.DataObjectException,
                                          jobmatch.data.DatabaseManagerException

createExisting( BigDecimal ) Factory method creates a SchooltypeDO object by searching for it in the database using the passed BigDecimal value as the primary key. Creates a DO that represents an existing entry in the database. Such a DO is used to examine and possibly update such an entry. createExisting() is called only from the code that retrieves an ObjectId from a ResultSet (database query result). createExisting() is protected because no other DO or BO should ever need to call it. FIX unfortunately the createExisting(BigDecimal) form *does* need to be public because it is called by the public ctors of other DOs. For example, AaaDO contains a ref to a BbbDO, so there is a method AaaDO.setBbb(BbbDO). In the ctor AaaDO(ResultSet), we have the call setBbb( BbbDO.createExisting( rs.getBigDecimal( "bbb", 0 ))); Since AaaDO is not in the same package as BbbDO, BbbDO.createExisting(BigDecimal) must be public, not protected. Java needs the C++ 'friend' idea.

Parameters:

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