Method Detail

Class<? extends S> type

()

Returns the provider type. There is no guarantee that this type is accessible or that it has a public no-args constructor. The get() method should be used to obtain the provider instance.

Returns:

The provider type

get

S get

()

Returns an instance of the provider.

Specified by:

get in interface Supplier<S>

Returns:

An instance of the provider.

Throws:

ServiceConfigurationError - If the service provider cannot be instantiated, or in the case of a provider factory, the public static "provider()" method returns null or throws an error or exception. The ServiceConfigurationError will carry an appropriate cause where possible.
