Class KeyManagerLocator

java.lang.Object
  de.schlichtherle.truezip.key.sl.KeyManagerLocator

All Implemented Interfaces:

KeyManagerService

@Immutable
@DefaultAnnotation(value=edu.umd.cs.findbugs.annotations.NonNull.class)
public final class KeyManagerLocator
extends Object
implements KeyManagerService

Locates a key manager 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.key.KeyManagerService" 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.key.KeyManagerService". 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.
