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:

createNew in interface Initializable

Returns:

destroy

public boolean destroy()

Description copied from interface: Initializable

Destroy the object completely. Returns true if the object existed before destroy was called. Further calls to this object must fail after this invocation.

Specified by:

destroy in interface Initializable

init

public boolean init()

Description copied from interface: Initializable

Initialize an existing object. This throws an exception if the object does not exist. The state after this call is exactly as if the system were created for the first time. Calls to the object before invocation have no guarantee of success.

Specified by:

init in interface Initializable

Returns:

Returns True if the operation succeeds.

isCreated

Description copied from interface: Initializable

(Optional) Returns true if the object in question has been created. If this cannot be determined then the call should throw an exception.

Specified by:

isCreated in interface Initializable

Returns:

isInitialized

public boolean isInitialized()

Description copied from interface: Initializable
