Array of linear rings that define the polygon. The first linear ring of the
array defines the outer-boundary or surface of the polygon. Each subsequent
linear ring defines a hole in the surface of the polygon. A linear ring is
an array of vertices' coordinates where the first coordinate and the last are
equivalent. (For internal use, flat coordinates in combination with
layout and ends are also accepted.)
Optionallayout: GeometryLayoutLayout.
Optionalends: number[]Ends (for internal use with flat coordinates).
ProtecteddisposedThe object has already been disposed.
ProtectedflatProtectedlayoutProtectedsimplifiedProtectedsimplifiedAbstractsimplifyGet a transformed and simplified version of the geometry.
ProtectedstrideAppend the passed linear ring to this polygon.
Linear ring.
ProtectedapplyProtectedApply any properties from another object without triggering events.
The source object.
AbstractapplyApply a transform function to the coordinates of the geometry.
The geometry is modified in place.
If you do not want the geometry modified in place, first clone() it and
then use this function on the clone.
Transform function. Called with a flat array of geometry coordinates.
AbstractclosestProtected AbstractcomputeDispatches an event and calls all listeners listening for events
of this type. The event parameter can either be a string or an
Object with a type property.
Event object.
false if anyone called preventDefault on the
event object or if any of the listeners returned false.
ProtecteddisposeGet the coordinate array for this geometry. This array has the structure of a GeoJSON coordinate array for polygons.
Optionalright: booleanOrient coordinates according to the right-hand
rule (counter-clockwise for exterior and clockwise for interior rings).
If false, coordinates will be oriented according to the left-hand rule
(clockwise for exterior and counter-clockwise for interior rings).
By default, coordinate orientation will depend on how the geometry was
constructed.
Coordinates.
Return the Nth linear ring of the polygon geometry. Return null if the
given index is out of range.
The exterior linear ring is available at index 0 and the interior rings
at index 1 and beyond.

Return the linear rings of the polygon.

Simplified geometry.
ProtectedgetAbstractgetAbstractintersectsProtectedonceProtectedonAbstractrotateAbstractscaleScale the geometry (with an optional origin). This modifies the geometry coordinates in place.
The scaling factor in the x-direction.
Optionalsy: numberThe scaling factor in the y-direction (defaults to sx).
Optionalanchor: CoordinateThe scale origin (defaults to the center of the geometry extent).
ProtectedsetSets a collection of key-value pairs. Note that this changes any existing properties and adds new ones (it does not remove any existing properties).
Values.
Optionalsilent: booleanUpdate without triggering an event.
Create a simplified version of this geometry. For linestrings, this uses the Douglas Peucker algorithm. For polygons, a quantization-based simplification is used to preserve topology.
The tolerance distance for simplification.
A new, simplified version of the original geometry.
AbstractsimplifyTransform each coordinate of the geometry from one coordinate reference
system to another. The geometry is modified in place.
For example, a line will be transformed to a line and a circle to a circle.
If you do not want the geometry modified in place, first clone() it and
then use this function on the clone.
The current projection. Can be a string identifier or a module:ol/proj/Projection~Projection object.
The desired projection. Can be a string identifier or a module:ol/proj/Projection~Projection object.
