Class LanguageBDO

Direct Known Subclasses:
Language

public class LanguageBDO
extends Object
implements Serializable

LanguageBDO contains the same set and get methods as the LanguageDO class. Business Object (BO) classes typically need these set and get methods. So by deriving a BO from a BDO, or by implementing a BO that contains a BDO, the developer of the BO is spared some work.

Field Detail

DO

protected LanguageDO DO
The LanguageDO object upon which the set and get methods operate. This member is protected so that classes derived from LanguageBDO can access the underlying Data Object.
Constructor Detail

LanguageBDO

public LanguageBDO(LanguageDO DO)
Constructor for use by classes derived from LanguageBDO. Example usage: class CustomerBO extends CustomerBDO { // a BDO class is commonly extended in order to implement: public void beforeAnySet() throws Exception { if ( CustomerDO should not be altered ) throw new ApplicationException( "ERROR" ); } public CustomerBO( CustomerDO DO ) { super( DO ); } } class SomePresentationLayerClass { public CustomerBO findCustomer( String name ) { CustomerQuery q = new CustomerQuery(); q.setQueryName( name ); CustomerDO DO = q.getNextDO(); // Here the CustomerBO ctor fires the CustomerBDO ctor. return new CustomerBO( DO ); } }

LanguageBDO

public LanguageBDO()
            throws Exception
Constructor required by LanguageBDO.create methods.
Method Detail

getDO

public LanguageDO getDO()
Note: This method is intended for use only by other BDO classes. Presentation Layer classes should (theoretically) always use the Business Layer (BDO) to create/access Data Layer (DO) objects. The overhead for using BDO objects is small (the BDO classes are fairly lightweight.)
Returns:
The DO object held by this BDO object.

createVirgin

public static LanguageBDO createVirgin()
                                throws Exception
Like the class LanguageDO, this class acts as a factory. Business Object (BO) classes typically need these set and get methods. So by deriving a BO from a BDO, or by implementing a BO that contains one or more BDOs, the developer of the BO is spared some work.
Throws:
Exception - If an error occurs.

createExisting

public static LanguageBDO createExisting(LanguageDO DO)
The createExisting method is used to create a LanguageBDO from a LanguageDO that was returned by the LanguageQuery class.

getBDOarray

public static LanguageBDO[] getBDOarray()
                                 throws jobmatch.data.DataObjectException
The getBDOarray method performs a database query to return an array of LanguageBDO objects representing all the rows in the Language table. This method is a minimal example of using a Query class. To restrict the set of objects returned, you could invoke query.setXxx(), where Xxx is an Attribute of LanguageDO which was marked as "Can be queried" in the DODS Attribute Editor.
Throws:
jobmatch.data.DataObjectException - If an object is not found in the database.

beforeAnyGet

protected void beforeAnyGet()
The developer of a Business Object that derives from this class can override the methods: beforeAnyGet beforeAnySet afterAnySet to handle any general assertions or cleanup needed for get and set methods.

beforeAnySet

protected void beforeAnySet()
                     throws Exception

afterAnySet

protected void afterAnySet()

getHandle

public String getHandle()
                 throws jobmatch.data.DatabaseManagerException
The methods getHandle hasMatchingHandle are used by Presentation Objects that need to populate HTML select lists with LanguageBDO objects as options. The getHandle() method is used to set the value for each option, and the hasMatchingHandle() methods are used to lookup the Data Object when the selection has been made. This LanguageBDO object holds a reference to a LanguageDO object. The id of this LanguageBDO is the id of its LanguageDO.
Returns:
id of this BDO as a string If an object id can't be allocated for this object.
Throws:
jobmatch.data.DatabaseManagerException - If a connection to the database cannot be established, etc.

hasMatchingHandle

public boolean hasMatchingHandle(String handle)
Parameters:
handle - String representation of the id for this BDO
Returns:
boolean True if the string version of the id of this DO matches passed handle
See Also:
getHandle

toString

public String toString()
for debugging
Overrides:
toString in class Object

getDescription

public String getDescription()
                      throws jobmatch.data.DataObjectException
Get Description of the LanguageDO
Returns:
Description of the LanguageDO
Throws:
jobmatch.data.DataObjectException - If the object is not found in the database.

setDescription

public void setDescription(String Description)
                    throws jobmatch.data.DataObjectException
Set Description of the LanguageDO
Parameters:
Description - of the LanguageDO
Throws:
jobmatch.data.DataObjectException - If the object is not found in the database.

getLanguageCandidateDOArray

public LanguageCandidateDO[] getLanguageCandidateDOArray()
                                                  throws jobmatch.data.DataObjectException,
