Detailed Description

A composite implementation of IFeatureHandlesProvider.

This composite allows you to:

• add instances: CompositeFeatureHandlesProvider::add
• remove instances: CompositeFeatureHandlesProvider::remove
• retrieve instances: CompositeFeatureHandlesProvider::getList

The composite implementation uses its delegate instances in a specific order. The order is based on the priority you assign when you add the delegate instance. If the priorities of two instances are equal, the instance that you added first gets priority.

A default implementation is available, see createDefault

2020.1

Constructor & Destructor Documentation

CompositeFeatureHandlesProvider()

luciad::CompositeFeatureHandlesProvider::CompositeFeatureHandlesProvider

(

)

Creates an empty composite instance.

~CompositeFeatureHandlesProvider()

luciad::CompositeFeatureHandlesProvider::~CompositeFeatureHandlesProvider ( )

override

Member Function Documentation

add()

void luciad::CompositeFeatureHandlesProvider::add	(	std::shared_ptr< IFeatureHandlesProvider >	handlesProvider,
		Priority	priority = Priority::normal()
	)

Adds the given instance to the list of registered instances with the given priority.

If you want to remove an instance again, use CompositeFeatureHandlesProvider::remove.

Parameters

handlesProvider	a new instance to register
priority	a priority. The default is PriorityDefault.

Exceptions

NullArgumentException

when nullptr is passed.

canProvide()

bool luciad::CompositeFeatureHandlesProvider::canProvide ( const std::shared_ptr< Observable< Feature > > &  feature, const std::shared_ptr< FeatureEditContext > &  context  ) const

overridevirtual

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

Parameters

feature	an observable Feature.
context	the context. Contains additional information about the edited feature.

Returns

if this handles provider can create handles for the given Feature.

Implements luciad::IFeatureHandlesProvider.

createDefault()

static std::shared_ptr< CompositeFeatureHandlesProvider > luciad::CompositeFeatureHandlesProvider::createDefault ( )

static

Creates a composite instance with a default set of instances that can handle any Feature instance that can be edited through its Geometry, using the configured geometry provider.

Returns

a composite instance with a default set of instances. These instances are registered using CompositeFeatureHandlesProvider::PriorityDefault.

getList()

std::vector< std::shared_ptr< IFeatureHandlesProvider > > luciad::CompositeFeatureHandlesProvider::getList

(

)

const

Returns

a list containing all registered instances, ordered by priority (highest priority first).

provide()

std::shared_ptr< IEditHandles > luciad::CompositeFeatureHandlesProvider::provide ( std::shared_ptr< Observable< Feature > >  feature, const std::shared_ptr< FeatureEditContext > &  context, std::shared_ptr< IFeatureEditCallback >  featureEditCallback  ) const

overridevirtual

Returns handles for the given feature.

If this provider doesn't support the given feature, it can return nullptr.

Parameters

feature	the observable feature for which to create handles.
context	the context. Contains additional information about the edited feature.
featureEditCallback	a callback that notifies the caller when the Feature has changed.

Returns

handles for the given feature. If this provider doesn't support the given feature, it can return nullptr.

Implements luciad::IFeatureHandlesProvider.

remove()

void luciad::CompositeFeatureHandlesProvider::remove

(

const std::shared_ptr< IFeatureHandlesProvider > &

handlesProvider

)

Removes this given instance from the list of registered instances.

Nothing will happen if the given instance was never added before.

Parameters

handlesProvider

the instance to remove from this composite.

Exceptions

NullArgumentException

when nullptr is passed.
