Class: QgsRangedoubleBase

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.

QgsDoubleRange

QgsRange which stores a range of double values.

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.
rangeLimits	Returns the limit handling of the range.
upper	Returns the upper bound of the range.

class qgis.core.QgsRangedoubleBase

Bases: object

__init__(lower: float, upper: float, includeLower: bool = True, includeUpper: bool = True)

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

Parameters:

• lower (float)

• upper (float)

• includeLower (bool = True)

• includeUpper (bool = True)

__init__(lower: float, upper: float, limits: Qgis.RangeLimits)

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

Added in version 3.38.

Parameters:

• lower (float)

• upper (float)

• limits (Qgis.RangeLimits)

__init__(a0: QgsRangedoubleBase)

Parameters:

a0 (QgsRangedoubleBase)
