Cast operators
These methods are used when the DataType is known. If they are applied to a ParamValue with the wrong DataType, an exception (Exception::ConversionError) is thrown. In particular, none of these operators will work for an empty ParamValue (DataType EMPTY_VALUE) - except toChar(), which will return 0.

Detailed Description

Class to hold strings, numeric values, vectors of strings and vectors of numeric values using the stl types.

• To choose one of these types, just use the appropriate constructor.
• Automatic conversion is supported and throws Exceptions in case of invalid conversions.
• An empty object is created with the default constructor.
