RandomAccessVectorValues (Lucene 9.6.0 core API)

```
public interface RandomAccessVectorValues<T>
```
Provides random access to vectors by dense ordinal. This interface is used by HNSW-based implementations of KNN search.

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

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`RandomAccessVectorValues<T>`	`copy()`	Creates a new copy of this `RandomAccessVectorValues`.
`int`	`dimension()`	Return the dimension of the returned vector values
`int`	`size()`	Return the number of vector values
`T`	`vectorValue(int targetOrd)`	Return the vector value indexed at the given ordinal.

- Method Detail
  - size
```
int size()
```
    Return the number of vector values
  - dimension
```
int dimension()
```
    Return the dimension of the returned vector values
  - vectorValue
```
T vectorValue(int targetOrd)
       throws IOException
```
    Return the vector value indexed at the given ordinal.
    
    Parameters:
    
    targetOrd - a valid ordinal, ≥ 0 and < size().
    
    Throws:
    
    IOException
  - copy
```
RandomAccessVectorValues<T> copy()
                          throws IOException
```
    Creates a new copy of this RandomAccessVectorValues. This is helpful when you need to access different values at once, to avoid overwriting the underlying float vector returned by vectorValue(int).
    
    Throws:
    
    IOException
