getDatabaseDescriptorImpl

protected abstract DatabaseDescriptor getDatabaseDescriptorImpl(java.lang.Class providerClass)

Gets a descriptor for the given database implementation class.

Parameters:

providerClass - the class of provider/database

Returns:

a descriptor for that class of database, or null if the class is not recognized by this creator.

getDatabaseDescriptorImpl

protected DatabaseDescriptor getDatabaseDescriptorImpl(Database db)

Called when a Database needs its own descriptor. The default implementation gets the Class of the database and calls getDatabaseDescriptorImpl(Class). If type/version were supplied on construction of the database an implementation of this method can call {Database#getDatabaseType()} and {Database#getDatabaseVersion()} to determine the appropriate descriptor.

Parameters:

db - the database instance that we need a descriptor for

Returns:

the descriptor for the database, or null if the database is not recognised by this creator.

getDatabaseDescriptorImpl

protected DatabaseDescriptor getDatabaseDescriptorImpl(java.lang.String type,
                                                       int ver)

Called from the DatabaseRegistry when the descriptor for a given type/version is requested.

Parameters:

type - the database type

ver - the database version

Returns:

a descriptor that describes the behaviour of the database type and version.
