ServiceLoader.Provider (Java SE 10 & JDK 10 )
Keywords: java.util.ServiceLoader.Provider interface

Module java.base
Package java.util

## Interface ServiceLoader.Provider<S>

- Type Parameters:
    `S` - The service type
  All Superinterfaces:
    `Supplier<S>`
  Enclosing class:
    ServiceLoader<S>

      public static interface ServiceLoader.Provider<S>
      extends Supplier<S>

  Represents a service provider located by `ServiceLoader`.

  When using a loader's `stream()` method then the elements are of type `Provider`. This allows processing to select or filter on the provider class without instantiating the provider.

    All Methods Instance Methods Abstract Methods

    `Class<? extends S>` | `type()` | Returns the provider type.

- - ### Method Detail

    - #### type

          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.

      When a module declares that the provider class is created by a provider factory then this method returns the return type of its public static "`provider()`" method.

      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.
