public abstract class ConfigurationSpi extends Object
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.

protected void |

Refresh and reload the Configuration.

protected abstract AppConfigurationEntry[] engineGetAppConfigurationEntry(String name)
name
- the name used to index the Configuration.protected void engineRefresh()
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.
SecurityException
- if the caller does not have permission
to refresh its Configuration. Submit a bug or feature
