Modifier and Type	Method	Description
`double[]`	`getDoubleVector()`	Get the current vector, casting to doubles as necessary.
`float[]`	`getFloatVector()`	Get the current vector, casting to floats as necessary.
`long[]`	`getLongVector()`	Get the current vector, casting to longs as necessary.
`boolean[]`	`getNullVector()`	Gets a vector of booleans signifying which rows are null and which are not (true for null).

- Method Detail
  - getLongVector
```
long[] getLongVector()
```
    Get the current vector, casting to longs as necessary. The array will be reused, so it is not a good idea to retain a reference to it.
  - getFloatVector
```
float[] getFloatVector()
```
    Get the current vector, casting to floats as necessary. The array will be reused, so it is not a good idea to retain a reference to it.
  - getDoubleVector
```
double[] getDoubleVector()
```
    Get the current vector, casting to doubles as necessary. The array will be reused, so it is not a good idea to retain a reference to it.
  - getNullVector
```
@Nullable
boolean[] getNullVector()
```
    Gets a vector of booleans signifying which rows are null and which are not (true for null). Returns null if it is known that there are no nulls in the vector, possibly because the column is non-nullable.
