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

Conversion operators

String	toString (bool full_precision=true) const
	Conversion to String `full_precision` Controls number of fractional digits for all double types or lists of double, 3 digits when false, and 15 when true. More...

QString	toQString () const
	Conversion to QString. More...

DataType	valueType () const
	returns the type of value stored More...

bool	isEmpty () const

DataType	value_type_
	Type of the currently stored value. More...

UnitType	unit_type_
	Type of the currently stored unit. More...

int32_t	unit_
	The unit of the data value (if it has one) using UO identifier, otherwise -1. More...

union {
SignedSize	ssize_

double	dou_

String *	str_

StringList *	str_list_

IntList *	int_list_

Detailed Description

Class to hold strings, numeric values, lists of strings and lists of numeric values.

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.
