Package Summary Overview Summary

class:ConfigurationSpi [NONE]

```
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.

Since:

1.6

constructor:<init>() [NONE]

ConfigurationSpi
```
public ConfigurationSpi()
```

method:engineGetAppConfigurationEntry(java.lang.String) [NONE]

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.

method:engineRefresh() [NONE]

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.
