Class: QgsDoubleRange

class qgis.core.QgsDoubleRange(lower: float, upper: float, includeLower: bool = True, includeUpper: bool = True)

Bases: sip.wrapper

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

QgsDoubleRange(QgsDoubleRange)

A template based class for storing ranges (lower to upper values).

QgsRange classes represent a range of values of some element type. For instance, ranges of int might be used to represent integer ranges.

Ranges can indicate whether the upper and lower values are inclusive or exclusive. The inclusivity or exclusivity of bounds is considered when determining things like whether ranges overlap or during calculation of range intersections.

Methods

contains Returns True if this range contains another range.
includeLower Returns True if the lower bound is inclusive, or False if the lower bound is exclusive.
includeUpper Returns True if the upper bound is inclusive, or False if the upper bound is exclusive.
isEmpty Returns True if the range is empty, ie the lower bound equals (or exceeds) the upper bound and either the bounds are exclusive.
isSingleton Returns True if the range consists only of a single value or instant.
lower Returns the lower bound of the range.
overlaps Returns True if this range overlaps another range.
upper Returns the upper bound of the range.
