de.schlichtherle.truezip.socket.sl
Class IOPoolLocator

java.lang.Object
  de.schlichtherle.truezip.socket.sl.IOPoolLocator

All Implemented Interfaces:: IOPoolProvider

@Immutable public final class IOPoolLocator
extends Object
implements IOPoolProvider
extends Object
implements IOPoolProvider

Locates an I/O pool service of a class with a name which is resolved by querying a system property or searching the class path, whatever yields a result first.

First, the value of the system property with the class name "de.schlichtherle.truezip.socket.spi.IOPoolService" as the key is queried. If this yields a value, the class with that name is then loaded and instantiated by calling its no-arg constructor.

Otherwise, the class path is searched for any resource file with the name "META-INF/services/de.schlichtherle.truezip.socket.spi.IOPoolService". If this yields a result, the class with the name in this file is then loaded and instantiated by calling its no-arg constructor.

Otherwise, a ServiceConfigurationError is thrown.

Field Detail

SINGLETON

public static final IOPoolLocator SINGLETON

The singleton instance of this class.

service

private final IOPoolService service

Constructor Detail

IOPoolLocator

private IOPoolLocator()

You cannot instantiate this class.

Method Detail

get

public IOPool<?> get()

Returns an I/O pool.

Calling this method several times may return different I/O pools, so callers might need to cache the result for subsequent use.

The implementation in the class IOPoolLocator delegates the call to the container loaded by the constructor.

Specified by:: get in interface IOPoolProvider

Returns:: An I/O pool.
