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.
