LineString class - geocore library

Constructors

LineString(Iterable<T> chain, {LineStringType type = LineStringType.any}): Create LineString from chain of points conforming by type.
LineString.any(Iterable<T> chain): Create LineString from chain of points (0 or >= 2 items).
factory
LineString.make(Iterable<Iterable<num>> values, PointFactory<T> pointFactory, {LineStringType type = LineStringType.any, Bounds<Point<num>>? bounds}): Create LineString from values with a chain of points.
factory
LineString.parse(String text, PointFactory<T> pointFactory, {LineStringType type = LineStringType.any, ParseCoordsList? parser}): Create LineString parsed from text with a chain of points.
factory
LineString.ring(Iterable<T> chain): Create a linear ring from a closed and simple chain of points.
factory

bounds → Bounds<Point<num>>?: The bounds for this object (could be calculated if not explicitely set).
no setter
boundsExplicit → Bounds<Point<num>>?: The explicit bounds for this object when available.
no setter
chain → PointSeries<T>: The chain of points forming this line string.
final
coordinates → Iterable<Position>: Coordinates of chain as 1-dimensional array of Position objects.
no setter
dimension → int: The topological dimension of this geometry.
no setteroverride
hashCode → int: The hash code for this object.
no setterinherited
isEmpty → bool: True if this geometry is considered empty without data or coordinates.
no setteroverride
isNotEmpty → bool: True if this geometry is NOT considered empty without data or coordinates.
no setterinherited
onePoint → Point<num>?: Returns one of points contained by this geometry if it's not empty.
no setteroverride
props → List<Object?>: The list of properties that will be used to determine whether two instances are equal.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
stringify → bool?: If set to true, the toString method will be overridden to output this instance's props.
no setterinherited
type → LineStringType: The type of this line string.
final
typeGeom → Geom: The type of this geometry.
no setteroverride

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
project<R extends Point<num>>(Projection projection, {required CreatePosition<R> to}) → LineString<R>: Returns a new geometry with all points projected using projection.
override
toString() → String: A string representation of this object.
override
toStringAs({TextWriterFormat<GeometryContent> format = DefaultFormat.geometry, int? decimals}) → String: A string representation of this geometry, with format applied.
inherited
transform(TransformPosition transform) → LineString<T>: Returns a new geometry with all points transformed using transform.
override
validate() → void: Throws if chain and type contains values not valid for a line string.
writeTo(SimpleGeometryContent writer) → void: Writes this geometry object to writer.
