Detailed Description

Member Function Documentation

`[override virtual noexcept]` ObserverTargetPairs::~ObserverTargetPairs()

Destructor.

`[static]` Esri::ArcGISRuntime::ObserverTargetPairs ObserverTargetPairs::create(const QList<Esri::ArcGISRuntime::ObserverTargetPair > &pairs, QObject **parent* = nullptr)

Creates an arbitrary arrangement of observer and target pairs.

pairs - Observer and target positions for the LineOfSightParameters. If this is empty, LineOfSightFunction::evaluateAsync will return an empty set of results.
parent - The optional parent QObject.

`[static]` Esri::ArcGISRuntime::ObserverTargetPairs ObserverTargetPairs::create(const QList<Esri::ArcGISRuntime::LineOfSightPosition > &observerPositions, const QList<Esri::ArcGISRuntime::LineOfSightPosition > &targetPositions*, QObject **parent* = nullptr)

Creates an observer target pair for each combination of the given observer and target positions.

observerPositions - Observer positions for the LineOfSightParameters. If this is empty, LineOfSightFunction::evaluateAsync will return an empty set of results.
targetPositions - Target positions for the LineOfSightParameters. If this is empty, LineOfSightFunction::evaluateAsync will return an empty set of results.
parent - The optional parent QObject.

Allows creation of pairs for the following scenarios: - One to one: Assess the visibility of one target to one observer. - One to many: Assess the visibility of multiple targets to one observer. - Many to one: Assess the visibility of one target to multiple observers. - Many to many: Assess the visibility of multiple targets to multiple observers.

pairs are ordered by observer, then target.

QList<Esri::ArcGISRuntime::ObserverTargetPair *> ObserverTargetPairs::pairs() const

Returns pairs of observers and targets, with each pair defining a single line of sight.

The collection of LineOfSight objects returned from LineOfSightFunction::evaluateAsync is ordered to match these pairs. Each LineOfSight corresponds to the ObserverTargetPair at the same index.

If this is empty, LineOfSightFunction::evaluateAsync will return an empty set of results.
