Class ConfigurationSpi

java.lang.Object
javax.security.auth.login.ConfigurationSpi
public abstract class ConfigurationSpi extends Object
This class defines the Service Provider Interface (SPI) for the Configuration class. 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 Configuration.Parameters object as an input parameter. This constructor also must throw an IllegalArgumentException if it does not understand the Configuration.Parameters input.

  • Method Details

    • 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.
