Class MessageData.Factory<M extends MessageData>

java.lang.Object

uk.ac.ed.epcc.webapp.model.data.DataObjectFactory<M>

uk.ac.ed.epcc.webapp.model.log.MessageData.Factory<M>

Type Parameters:

M -

All Implemented Interfaces:

Contexed, ContextCached, FormCreatorProducer, FormUpdateProducer<M>, FilterMatcher<M>, TypeConverter<M,java.lang.Number>, DataObjectSelector<M>, Selector<DataObjectItemInput<M>>, Owner<M>, IndexedProducer<M>, Tagged, Targetted<M>

Enclosing class:

MessageData

public static class MessageData.Factory<M extends MessageData>
extends DataObjectFactory<M>

A Factory for MessageData This is not actually needed by the application but makes the tests easier to write as these rely on a handler factory

Factory

Method Detail

getDefaultTableSpecification

protected TableSpecification getDefaultTableSpecification(AppContext c,
                                                          java.lang.String table)

Description copied from class: DataObjectFactory

Get the default table specification if the table is to be created. A null result means that a default specification is not available and the table will not be created.

Overrides:

getDefaultTableSpecification in class DataObjectFactory<M extends MessageData>

Parameters:

c - AppContext

table - String table name.

Returns:

null or TableSpecification

makeBDO

protected M makeBDO(Repository.Record res)
             throws DataFault

Description copied from class: DataObjectFactory

Construct a new Blank DataObject of the correct Class This method takes a Record as an argument. This allows the factory to either create different sub-classes depending on a value in the record or to produce objects from different Repositories/tables. We keep the return type as DataObject instead of making it generic as this helps with legacy compatibility a little bit (problem is if we have another generic sub-type between us and a legacy sub-class

Specified by:

makeBDO in class DataObjectFactory<M extends MessageData>

Parameters:

res - Record to create object from

Returns:

new object of correct class.

Throws:

DataFault

getTarget

public java.lang.Class<M> getTarget()

Description copied from class: DataObjectFactory

Get a bound on the type of object produced by this factory for run-time checking. This implements IndexedProducer.getTarget(). Normally this method should be overridden each time we make a sub-class that narrows the produced type. However checks should still pass if the super-type method is retained.

Specified by:

getTarget in interface IndexedProducer<M extends MessageData>

Specified by:

getTarget in interface Targetted<M extends MessageData>

Overrides:

getTarget in class DataObjectFactory<M extends MessageData>

Returns:

Class object for return type
