- Method Detail
  - __vector
```
protected int __vector()
```
    Get the start data of a vector.
    
    Returns:
    
    Returns the start of the vector data.
  - __element
```
protected int __element(int j)
```
    Gets the element position in vector's ByteBuffer.
    
    Parameters:
    
    j - An `int` index of element into a vector.
    
    Returns:
    
    Returns the position of the vector element in a ByteBuffer.
  - __reset
```
protected void __reset(int _vector,
                       int _element_size,
                       java.nio.ByteBuffer _bb)
```
    Re-init the internal state with an external buffer ByteBuffer, an offset within and element size. This method exists primarily to allow recycling vector instances without risking memory leaks due to ByteBuffer references.
  - reset
```
public void reset()
```
    Resets the internal state with a null ByteBuffer and a zero position. This method exists primarily to allow recycling vector instances without risking memory leaks due to ByteBuffer references. The instance will be unusable until it is assigned again to a ByteBuffer.
  - length
```
public int length()
```
    Get the length of a vector.
    
    Returns:
    
    Returns the length of the vector.
