Detailed Description

Creates new symbology features.

This feature creator will

• use an initial military symbol feature instance as a base
• create a geometry on the map
• fill in the remaining Feature values using the created geometry

Example

  // set up a Creator for the feature and its geometry.
  auto standard = MilitarySymbology::Standard::MilStd2525b;
  auto symbol = MilitarySymbol::create(standard, "G*G*GPAR--****X");
  auto featureCreator = std::make_shared<MilitarySymbolFeatureCreator>(symbol);
 
  // wire creation to the controller (here we're using DefaultController)
  defaultController->setCreator(Creator::newBuilder().layer(layer).map(map).featureCreator(featureCreator).build());

override

Member Function Documentation

onEvent()

EventResult luciad::MilitarySymbolFeatureCreator::onEvent ( const std::shared_ptr< IInputEvent > &  inputEvent, const std::shared_ptr< FeatureCreateContext > &  context  )

overridevirtual

Handles the given event, and returns if the event was handled or not.

Parameters

context	the creation context, cannot be nullptr
inputEvent	an event, cannot be nullptr

Returns

if the event was consumed or not

Exceptions

NullArgumentException

when nullptr is passed.

Implements luciad::IFeatureCreator.

start()

void luciad::MilitarySymbolFeatureCreator::start ( std::shared_ptr< IFeatureCreateCallback >  callback, const std::shared_ptr< FeatureCreateContext > &  context  )

overridevirtual

This method is called to start creation.

After this call, IFeatureCreator::onEvent can be called.

When a IFeatureCreator was started, it can not be started again until it has stopped. Implementations of this method are encouraged to throw an exception in that case to signal a programming error by the caller of this method.

Parameters

context	the creation context, cannot be nullptr
callback	the callback to signal feature changes, and whether creation for the feature has finished, cannot be nullptr.

Exceptions

NullArgumentException

when nullptr is passed.

Implements luciad::IFeatureCreator.
