isNullAt

- Method Detail
  - reset
```
void reset()
```
    Resets the column to default state.
  - setNullAt
```
void setNullAt(int rowId)
```
    Set null at rowId.
  - setNulls
```
void setNulls(int rowId,
              int count)
```
    Set nulls from rowId to rowId + count (exclude).
  - fillWithNulls
```
void fillWithNulls()
```
    Fill the column vector with nulls.
  - setDictionary
```
void setDictionary(Dictionary dictionary)
```
    Set the dictionary, it should work with dictionary ids.
  - hasDictionary
```
boolean hasDictionary()
```
    Check if there's a dictionary.
  - reserveDictionaryIds
```
WritableIntVector reserveDictionaryIds(int capacity)
```
    Reserve a integer column for ids of dictionary. The size of return WritableIntVector should be equal to or bigger than capacity. DictionaryIds must inconsistent with setDictionary(org.apache.flink.table.data.columnar.vector.Dictionary). We don't support a mix of dictionary.
  - getDictionaryIds
```
WritableIntVector getDictionaryIds()
```
    Get reserved dictionary ids.
