java.lang.Object | +--jobmatch.data.LanguageBDO
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.

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 );
}

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.public static LanguageBDO createExisting(LanguageDO DO)

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.protected void beforeAnyGet()

public String getHandle() throws jobmatch.data.DatabaseManagerException
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.
