```
public boolean isNullOrEmpty()
```
    Description copied from interface: ClickHouseValue
    
    Checks if the value is null, or empty for non-null types like Array, Tuple and Map.
    Please pay attention that only nullability will be considered for String, meaning this method will return false for an empty string. This is because String is treated as value-based type instead of a container like Array.
    
    Specified by:
    
    isNullOrEmpty in interface ClickHouseValue
    
    Overrides:
    
    isNullOrEmpty in class ClickHouseObjectValue<T[]>

```
    Description copied from interface: ClickHouseValue
    
    Resets value to null, or empty when null is not supported(e.g. Array, Tuple and Map etc.).
    Keep in mind that String is value-based type, so this method will change its value to null instead of an empty string.
    
    Specified by:
    
    resetToNullOrEmpty in interface ClickHouseValue
    
    Overrides:
