All Implemented Interfaces:

Closeable, Serializable, AutoCloseable
```
@Deprecated
public class InstantiatedIndex
extends Object
implements Serializable, Closeable
```
Deprecated.
contrib/instantiated will be removed in 4.0; you can use the memory codec to hold all postings in RAM

Represented as a coupled graph of class instances, this all-in-memory index store implementation delivers search results up to a 100 times faster than the file-centric RAMDirectory at the cost of greater RAM consumption.

Serialized Form

WARNING: This API is experimental and might change in incompatible ways in the next release.

There are no read and write locks in this store. InstantiatedIndexReader InstantiatedIndexReader.isCurrent() all the time and InstantiatedIndexWriter will attempt to update instances of the object graph in memory at the same time as a searcher is reading from it. Consider using InstantiatedIndex as if it was immutable.
