Method Detail

createNew

public boolean createNew()

Description copied from interface: Initializable

Creates a completely new instance. Fails if an instance already exists. In that case, call destroy first. For instance, this might create all file system entries or drop then recreate all tables in an SQL database. Compare this with init which might delete any entries in a file store or SQL table.

Specified by:

Returns:

destroy

Specified by:

destroy in interface Initializable

init

public boolean init()

Description copied from interface: Initializable

Specified by:

init in interface Initializable

Returns:

Returns True if the operation succeeds.
