Configurationclass. All the abstract methods in this class must be implemented by each service provider who wishes to supply a Configuration implementation.
Subclass implementations of this abstract class must provide
a public constructor that takes a
object as an input parameter. This constructor also must throw
an IllegalArgumentException if it does not understand the
Constructor SummaryConstructorDescriptionConstructor for subclasses to call.
ConfigurationSpipublic ConfigurationSpi()Constructor for subclasses to call.
engineGetAppConfigurationEntryRetrieve the AppConfigurationEntries for the specified
name- the name used to index the Configuration.
- an array of AppConfigurationEntries for the specified
name, or null if there are no entries.
engineRefreshprotected 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
refreshmay 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.
SecurityException- if the caller does not have permission to refresh its Configuration.
