  - cloneValue
```
public DataValueDescriptor cloneValue(boolean forceMaterialization)
```
    Description copied from interface: DataValueDescriptor
    
    Clone this DataValueDescriptor. Results in a new object that has the same value as this but can be modified independently.
    Even though the objects can be modified independently regardless of the value of forceMaterialization, both the clone and the original may be dependent on the store state if forceMaterialization is set to false. An example is if you need to access the value you just read using cloneValue after the current transaction has ended, or after the source result set has been closed.
    
    Parameters:
    
    forceMaterialization - any streams representing the data value will be materialized if true, the data value will be kept as a stream if possible if false
    
    Returns:
    
    A clone of the DataValueDescriptor with the same initial value as this.

  - typePrecedence
```
public int typePrecedence()
```
    Description copied from class: DataType
    
    Each built-in type in JSQL has a precedence. This precedence determines how to do type promotion when using binary operators. For example, float has a higher precedence than int, so when adding an int to a float, the result type is float. The precedence for some types is arbitrary. For example, it doesn't matter what the precedence of the boolean type is, since it can't be mixed with other types. But the precedence for the number types is critical. The SQL standard requires that exact numeric types be promoted to approximate numeric when one operator uses both. Also, the precedence is arranged so that one will not lose precision when promoting a type.
    
    Specified by:
    
    typePrecedence in interface DataValueDescriptor
    
    Overrides:
    
    typePrecedence in class DataType
    
    Returns:
    
    The precedence of this type.
