Detailed Description

A layer for raster models.

Use luciad::RasterLayer::newBuilder to create a raster layer instance.

Constructor & Destructor Documentation

◆ ~RasterLayer()

luciad::RasterLayer::~RasterLayer ( )

override

Member Function Documentation

◆ addObserver()

void luciad::RasterLayer::addObserver ( std::shared_ptr< ILayerObserver > layerObserver )

overridevirtual

Adds an observer that allows to receive change events from this layer.

Adding the same observer twice is forbidden, and will cause an exception to be thrown.

Parameters

layerObserver an observer.

Exceptions

luciad::InvalidArgumentException	when the observer was already added.
luciad::NullArgumentException	when the observer is `nullptr`.

Implements luciad::Layer.

◆ asBuilder()

Builder luciad::RasterLayer::asBuilder ( ) const

Returns a new builder based on this layer instance.

You can use this builder, for example, to create a copy of this layer.

Note that observers will not be transferred to a new layer.

Returns: a new builder based on this layer instance.

Since: 2024.1.03

◆ getLayerType()

RasterLayerType luciad::RasterLayer::getLayerType ( ) const

Returns the type of this raster layer.

Returns: this layer type.

Since: 2024.0

◆ getModel()

const std::shared_ptr< IRasterModel > & luciad::RasterLayer::getModel ( ) const

Returns the layer's model, which provides the raster to be presented.

Returns: the layer's model, which provides the raster to be presented.

◆ getRasterStyle()

const RasterStyle & luciad::RasterLayer::getRasterStyle ( ) const

Returns the raster style used for painting this layer.

Returns: the style of this layer.

Since: 2023.1

◆ getTitle()

const std::string & luciad::RasterLayer::getTitle ( ) const

overridevirtual

Returns the layer's title.

Should be suitable for presenting to the user.

Returns: the layer's title, should be suitable for presenting to the user.

Implements luciad::Layer.

◆ isBusy()

bool luciad::RasterLayer::isBusy ( ) const

overridevirtual

Returns whether this layer is busy loading data, rendering, loading attributions, or anything else.

When this property changes, a LayerEvent is delivered to the observers with the property name propertyBusy.

Note: when the map is moving around it can be that the layer is repeatedly loading new data, but does this fast enough that it is done by the time new data is needed, resulting in a repeatedly changing busyness state.

Returns: whether this layer is busy.

Since: 2024.1

Implements luciad::Layer.

◆ isVisible()

bool luciad::RasterLayer::isVisible ( ) const

overridevirtual

Returns whether this layer is visible.

Returns: whether this layer is visible.

Implements luciad::Layer.

◆ newBuilder()

static Builder luciad::RasterLayer::newBuilder ( )

static

Returns the new builder for creating a RasterLayer.

Returns: the new builder for creating a RasterLayer.

◆ propertyRasterStyle()

static const std::string & luciad::RasterLayer::propertyRasterStyle ( )

static

Property name for the LayerEvent that is fired as a result of changing the layer's style.

See also: setRasterStyle

Since: 2023.1

◆ removeObserver()

void luciad::RasterLayer::removeObserver ( const std::shared_ptr< ILayerObserver > & layerObserver )

overridevirtual

Removes the given observer.

If the given observer was never added, an exception is thrown.

Parameters

layerObserver an observer.

Exceptions

luciad::InvalidArgumentException	when the observer is not known.
luciad::NullArgumentException	when the observer is `nullptr`.

Implements luciad::Layer.

◆ setRasterStyle()

void luciad::RasterLayer::setRasterStyle ( RasterStyle rasterStyle )

Sets the raster style used for painting this layer.

If the new raster style is different from the old one, a LayerEvent is delivered to the observers with the property name PropertyRasterStyle.

Parameters

rasterStyle the new raster style.

Since: 2023.1

◆ setTitle()

void luciad::RasterLayer::setTitle ( std::string title )

overridevirtual

Sets the layer's title.

Should be suitable for presenting to the user.

If the new title is indeed different from the old one, a LayerEvent is delivered to the observers with the property name PropertyTitle.

Parameters

title the new title.

Implements luciad::Layer.

◆ setVisible()

void luciad::RasterLayer::setVisible ( bool visible )

overridevirtual

Sets whether this layer is visible.

Changes this layer's visibility. If the new visibility is different from the old one, a LayerEvent is delivered to the observers with the property name PropertyVisible.

Parameters

visible the new visibility.

Implements luciad::Layer.
