  - close
```
public void close()
```
    Cleans up memory for this column vector. The column vector is not usable after this.
    This overwrites `AutoCloseable.close` to remove the `throws` clause, as column vector is in-memory and we don't expect any exception to happen during closing.
    
    指定者:
    
    close 在接口中 AutoCloseable
    
    指定者:
    
    close 在类中 TiColumnVector
