Detailed Description

This handles provider can create handles to edit Point geometries.

The handles provider offers the following handles:

A handle to change the height of the point. Note that the default implementation of PointHandlesProvider::IHandleFactory automatically omits these handles on a 2D map, or on a 3D map when for points without elevation.

Note: the handle to translate the entire feature is typically created by the IFeatureHandlesProvider. FeatureHandlesProvider does this by default.

Since: 2020.1

Constructor & Destructor Documentation

◆ PointHandlesProvider()

luciad::PointHandlesProvider::PointHandlesProvider ( )

Creates a new PointHandlesProvider that can create handles to modify Point geometries.

◆ ~PointHandlesProvider()

Member Function Documentation

◆ canProvide()

bool luciad::PointHandlesProvider::canProvide	(	const std::shared_ptr< Observable< std::shared_ptr< Geometry > > > &	geometry,
		const std::shared_ptr< FeatureEditContext > &	context
	)		const

overridevirtual

Indicates if this handles provider can create handles for the given geometry.

Parameters

geometry	an observable geometry, cannot be `nullptr`
context	the context. Contains additional information about the edited feature, cannot be `nullptr`.

Returns: if this handles provider can provide handles and a translate action for the given Feature

Implements luciad::IGeometryHandlesProvider.

◆ getConstraint()

std::shared_ptr< IPointConstraint > luciad::PointHandlesProvider::getConstraint ( ) const

Returns: constraint the constraint that is applied to the handles' edit actions, or nullptr if no constraint is set.

◆ getHandleFactory()

std::shared_ptr< IHandleFactory > luciad::PointHandlesProvider::getHandleFactory ( ) const

Returns: the handle factory used by the handles provider

◆ provide()

std::shared_ptr< IEditHandles > luciad::PointHandlesProvider::provide	(	std::shared_ptr< Observable< std::shared_ptr< Geometry > > >	geometry,
		const std::shared_ptr< FeatureEditContext > &	context,
		std::shared_ptr< IGeometryEditCallback >	geometryEditCallback
	)		const

overridevirtual

Returns the handles for the given feature.

Note: translation of features is handled by IFeatureHandlesProvider. So geometry handles providers should not provide handles to translate a geometry.

Parameters

geometry	the observable geometry for which to provide handles, cannot be `nullptr`.
context	the context. Contains additional information about the edited feature, cannot be `nullptr`.
geometryEditCallback	a callback that notifies the caller when the Feature has changed, cannot be `nullptr`.

Returns: handles for the given feature. Never nullptr.

Implements luciad::IGeometryHandlesProvider.

◆ provideTranslateAction()

std::shared_ptr< ITranslateEditAction > luciad::PointHandlesProvider::provideTranslateAction	(	std::shared_ptr< Observable< std::shared_ptr< Geometry > > >	geometry,
		const std::shared_ptr< FeatureEditContext > &	context,
		std::shared_ptr< IGeometryEditCallback >	geometryEditCallback
	)		const

overridevirtual

Provides a translate action that can be used by the caller to add translation behavior.

A translation handle is typically added by an IFeatureHandlesProvider, like for example the FeatureHandlesProvider implementation. It calls this method to retrieve a translate action, and uses it to create a TranslateEditHandle.

When ITranslateEditAction::translate is called, the returned implementation must:

apply a translation on the geometry
apply this IGeometryHandlesProvider's constraint (if configured) on the translated geometry
call IGeometryEditCallback with the resulting geometry

Parameters

geometry	the observable geometry for which to provide a translate action, cannot be `nullptr`
context	the context, cannot be `nullptr`
geometryEditCallback	a callback that notifies the caller of this method when a translation has occurred, cannot be `nullptr`

Returns: a translate action. Never nullptr.

Implements luciad::IGeometryHandlesProvider.

◆ setConstraint()

void luciad::PointHandlesProvider::setConstraint ( std::shared_ptr< IPointConstraint > constraint )

Sets the constraint that is applied to the handles created by this handles provider.

Handles always call the constraint with a PointChange parameter, containing the point difference.

Parameters

constraint the constraint that is applied to the handles' edit actions, or nullptr if no constraint should be applied.

◆ setHandleFactory()

void luciad::PointHandlesProvider::setHandleFactory ( std::shared_ptr< IHandleFactory > handleFactory )

Sets the IHandleFactory that is used to create handles by this provider.

If this method is not called, a default handle factory is used. You can change the behavior of this default handle factory by:

retrieving it
wrapping it with your own IHandleFactory implementation, by delegating to the default factory
omitting/replacing one or more handles that are returned

Parameters

handleFactory a handle factory

Exceptions

NullArgumentException when nullptr is passed.
