LengthLocationMap class

Computes the {@link LinearLocation} for a given length along a linear {@link Geometry}. Negative lengths are measured in reverse from end of the linear geometry. Out-of-range values are clamped.

Constructors

LengthLocationMap(Geometry linearGeom)

Properties

hashCode → int

The hash code for this object.

no setter, inherited

linearGeom ↔ Geometry

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

Methods

getLength(LinearLocation loc) → double

getLocation(double length) → LinearLocation

Compute the {@link LinearLocation} corresponding to a length. Negative lengths are measured in reverse from end of the linear geometry. Out-of-range values are clamped. Ambiguous indexes are resolved to the lowest possible location value.

getLocationForward(double length) → LinearLocation

getLocationWithResolver(double length, bool resolveLower) → LinearLocation

Compute the {@link LinearLocation} corresponding to a length. Negative lengths are measured in reverse from end of the linear geometry. Out-of-range values are clamped. Ambiguous indexes are resolved to the lowest or highest possible location value, depending on the value of resolveLower

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

resolveHigher(LinearLocation loc) → LinearLocation

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

getLengthStatic(Geometry linearGeom, LinearLocation loc) → double

Computes the length for a given {@link LinearLocation} on a linear {@link Geometry}.

getLocationStatic(Geometry linearGeom, double length) → LinearLocation

Computes the {@link LinearLocation} for a given length along a linear {@link Geometry}.

getLocationStaticWithResolver(Geometry linearGeom, double length, bool resolveLower) → LinearLocation

Computes the {@link LinearLocation} for a given length along a linear {@link Geometry}, with control over how the location is resolved at component endpoints.
