VectorizationProvider (Lucene 9.11.1 core API)

java.lang.Object
- org.apache.lucene.internal.vectorization.VectorizationProvider

```
public abstract class VectorizationProvider
extends Object
```
A provider of vectorization implementations. Depending on the Java version and availability of vectorization modules in the Java runtime this class provides optimized implementations (using SIMD) of several algorithms used throughout Apache Lucene.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
