Method Detail

engineGetAppConfigurationEntry

protected abstract AppConfigurationEntry[] engineGetAppConfigurationEntry(String name)

Retrieve the AppConfigurationEntries for the specified name.

Parameters:

name - the name used to index the Configuration.

Returns:

an array of AppConfigurationEntries for the specified name, or null if there are no entries.

engineRefresh

protected void engineRefresh()

Refresh and reload the Configuration.

This method causes this Configuration object to refresh/reload its contents in an implementation-dependent manner. For example, if this Configuration object stores its entries in a file, calling refresh may cause the file to be re-read.

The default implementation of this method does nothing. This method should be overridden if a refresh operation is supported by the implementation.

Throws:

SecurityException - if the caller does not have permission to refresh its Configuration.
