Method Detail

init

void init()
          throws IOException

Initialize the configuration settings.

Throws:

IOException - if the configuration settings could not be initialized because of an I/O problem.

load

void load()
          throws IOException

Load the configuration settings. Settings will be loaded from a user and application specific location first. If no such settings exists, an attempt will be made to retrieve settings from a resource on the classpath. If no such settings exist either, settings will be loaded from a default resource on the classpath.

Throws:

IOException - if the configuration settings could not be loaded due to an I/O problem.

save

void save()
          throws IOException

Store configuration settings. Settings will be stored in a user and application specific location.

Throws:

IOException - if the configuration settings could not be saved due to an I/O problem.

destroy

void destroy()
             throws IOException

Clean up configuration resources.

Throws:

IOException - if one or more resources could not be cleaned up. Implementations should attempt to clean up as many resources as possible before returning or throwing an exception.
