SingleInstanceLockFactory

public class SingleInstanceLockFactory extends LockFactory
Implements {@link LockFactory} for a single in-process instance, meaning all locking will take place through this one instance. Only use this {@link LockFactory} when you are certain all IndexReaders and IndexWriters for a given index are running against a single shared in-process Directory instance. This is currently the default locking for RAMDirectory.
