Detailed Description

This class can create patch instances, based on other created geometries.

It is a wrapper class, that takes the result of another IGeometryCreator, and creates a Patch from Ring geometries that are created. If the wrapped creator does not create a Ring, it is left as-is.

This creator doesn't consume any events itself, but it delegates the events to the wrapped creator instance.

Constructor & Destructor Documentation

PatchCreator()

luciad::PatchCreator::PatchCreator ( std::shared_ptr< IGeometryCreator >  delegateCreator )

explicit

Creates a new PatchCreator.

Parameters

delegateCreator

the delegate creator to use

~PatchCreator()

luciad::PatchCreator::~PatchCreator ( )

override

Member Function Documentation

onEvent()

EventResult luciad::PatchCreator::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 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::IGeometryCreator.

start()

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

overridevirtual

This method is called to start creation.

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

When a IGeometryCreator was started, it can not be started again until it has finished. 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 context, cannot be nullptr
callback	the callback to signal geometry changes, and whether creation for the geometry has finished, cannot be nullptr.

Exceptions

NullArgumentException

when nullptr is passed.

Implements luciad::IGeometryCreator.
