public static Object getRowValue(com.datastax.oss.driver.api.core.cql.Row row,
 int index,
 @Nullable
 Class<?> requiredType)

Retrieve a CQL column value from a Row, using the specified value type.

Uses the specifically typed Row accessor methods, falling back to GettableByIndex.getObject(int) for unknown types.

Note that the returned value may not be assignable to the specified required type, in case of an unknown type. Calling code needs to deal with this case appropriately, e.g. throwing a corresponding exception.

Parameters:

row - is the Row holding the data

index - is the column index

requiredType - the required value type (may be null)

Returns:

the value object
