Interface ExtensionPoint

public interface ExtensionPoint

A very simple interface that indicates service provider extension points. The idea is that some service provider interfaces are extension points in the sense that there might be custom implementation of the interface that are lookup up by the ServiceLoader used by the respective service. Implementations are identified by a name. This interface defines hasName(String) to check whether a service provider matches the sought name or not.

The contract is that service providers must always accept their qualified class name.

Method Summary

String	getName() The custom name of the service provider.

Method Detail

hasName

default boolean hasName(String providername)

The naming contract enforces that each provider must accept its own qualified class name as provider name. Other names are optional and might facilitate the usage of the provider in the configuration file.

Parameters:

providername - A name to check whether it matches the name of a provider.

Returns:

True, if the given name matches the provider's, false otherwise.

getName

String getName()

The custom name of the service provider. The term 'custom' here means some simple name and not the qualified class name, which is always a valid identifier.

Returns:

The name of the implementing service provider.
