Method Detail

getDefaultTableSpecification

public TableSpecification getDefaultTableSpecification(AppContext c,
                                                       java.lang.String homeTable)

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 HistoryFactory<T extends IndexedLinkManager.Link<L,R>,H extends HistoryFactory.HistoryRecord<T>>

Parameters:

c - AppContext

homeTable - String table name.

Returns:

null or TableSpecification
