Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`BytesRef`	`binaryValue(int targetOrd)`	Return the vector indexed at the given ordinal value as an array of bytes in a BytesRef; these are the bytes corresponding to the float array.
`int`	`dimension()`	Return the dimension of the returned vector values
`int`	`size()`	Return the number of vector values
`float[]`	`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
```
float[] vectorValue(int targetOrd)
             throws java.io.IOException
```
    Return the vector value indexed at the given ordinal. The provided floating point array may be shared and overwritten by subsequent calls to this method and binaryValue(int).
    
    Parameters:
    
    targetOrd - a valid ordinal, ≥ 0 and < size().
    
    Throws:
    
    java.io.IOException
  - binaryValue
```
BytesRef binaryValue(int targetOrd)
              throws java.io.IOException
```
    Return the vector indexed at the given ordinal value as an array of bytes in a BytesRef; these are the bytes corresponding to the float array. The provided bytes may be shared and overwritten by subsequent calls to this method and vectorValue(int).
    
    Parameters:
    
    targetOrd - a valid ordinal, ≥ 0 and < size().
    
    Throws:
    
    java.io.IOException
