Constructor & Destructor Documentation

◆ QgsDoubleRange()

QgsDoubleRange::QgsDoubleRange ( double  lower = std::numeric_limits< double >::lowest(),
double  upper = std::numeric_limits< double >::max(),
bool  includeLower = true,
bool  includeUpper = true 
)
inline

Constructor for QgsDoubleRange.

The lower and upper bounds are specified, and optionally whether or not these bounds are included in the range.

The default values for lower and upper construct an infinite range (see isInfinite()).
