Class: QgsMultiLineString¶

Multi line string geometry collection.

Class Hierarchy¶

`QgsMultiCurve`	Multi curve geometry collection.
`QgsGeometryCollection`	Geometry collection
`QgsAbstractGeometry`	Abstract base class for all geometries

Methods

`lineStringN`	Returns the line string with the specified index.
`measuredLine`	Re-write the measure ordinate (or add one, if it isn't already there) interpolating the measure between the supplied start and end values.
`toCurveType`	Returns the geometry converted to the more generic curve type `QgsMultiCurve`

class qgis.core.QgsMultiLineString[source]¶

Bases: QgsMultiCurve

__init__(linestrings: Iterable[QgsLineString])

Constructor for a multilinestring containing the specified linestrings.

The linestrings will be internally cloned.

Added in version 3.38.

__init__(linestrings: Iterable[QgsLineString])

Constructor for a multilinestring containing the specified linestrings.

Ownership of the linestrings will be transferred to the multilinestring.

Added in version 3.38.

lineStringN(self, index: int) → QgsLineString[source]¶

Returns the line string with the specified index.

Raises:: IndexError – if no line string with the specified index exists.

Added in version 3.16.

measuredLine(self, start: float, end: float) → QgsMultiLineString | None[source]¶

Re-write the measure ordinate (or add one, if it isn’t already there) interpolating the measure between the supplied start and end values.

Added in version 3.36.

Parameters:

Return type:

Optional[QgsMultiLineString]

toCurveType(self) → QgsMultiCurve | None[source]¶

Returns the geometry converted to the more generic curve type QgsMultiCurve
