ServerProvider (jdisc_core 7.458.20 API)

All Superinterfaces:

SharedResource

All Known Implementing Classes:

AbstractServerProvider, NonWorkingServerProvider
```
public interface ServerProvider
extends SharedResource
```
This interface defines a component that is capable of acting as a server for an external client. To activate a ServerProvider it must be installed in a ContainerBuilder, and that builder must be activated.

If a ServerProvider is to expire due to Application reconfiguration, it is necessary to close() that ServerProvider before deactivating the owning Container. Typically:
```
 myExpiredServers.close();
 reconfiguredContainerBuilder.servers().install(myRetainedServers);
 containerActivator.activateContainer(reconfiguredContainerBuilder);
 
```
All implementations of this interface will need to have a CurrentContainer injected into its constructor so that it is able to create and dispatch new Requests.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`close()`	This is a synchronous method to close the listen port (or equivalent) of this ServerProvider and flush any input buffers that will cause calls to `CurrentContainer.newReference(URI)`.
`void`	`start()`	This is a synchronous method to configure this ServerProvider and bind the listen port (or equivalent).

- Method Detail
  - start
```
void start()
```
    This is a synchronous method to configure this ServerProvider and bind the listen port (or equivalent). The Container does not call this method, instead it is a required step in the Application initialization code.
  - close
```
void close()
```
    This is a synchronous method to close the listen port (or equivalent) of this ServerProvider and flush any input buffers that will cause calls to CurrentContainer.newReference(URI). This method must not return until the implementation can guarantee that there will be no further calls to CurrentContainer. All previously dispatched Requests are processed as before.
    
    The Container does not call this method, instead it is a required step in the Application shutdown code.
