public class TLspAPP6ALayerBuilder
extends ALspLayerBuilder

Builder for layers capable of visualizing APP6 shapes.

The layer will contain two paint representations that can be controlled separately:

• TLspPaintRepresentation.BODY: the main body
• TLspPaintRepresentation.LABEL: the labels

For non-line symbols, the body visualisation consists of an icon. For line symbols, the body visualisation depends on the symbol. It typically consists of a line or area.

Basic customization of the visualization is possible using an ILcdAPP6AStyle. If the domain object implements ILcdAPP6AStyled, then the style will be retrieved from it. Otherwise, a default style is used.

Other customization of the visualization is possible by setting a custom body or label styler. This layer builder installs a TLspAPP6ASymbolStyler by default. This styler recognizes domain objects which implement ILcdAPP6ACoded and ILcdAPP6AStyled. Replacing the default styler with a custom one allows APP6 symbology to be used on domain objects which do not implement these interfaces, as well as making all sorts of other customizations possible (e.g. additional decorations or labels on symbols).

Note that the created layer will not have the specified styler directly as its label styler.

Parameters:

aPaintState - the paint state for which to set the label styler

aStyler - the new label styler for the layer

Returns:

this

ILspLayer.getLayerType()

bodyEditable

public TLspAPP6ALayerBuilder bodyEditable(boolean aEditable)

Sets whether the body of the symbols should be editable.

Parameters:

aEditable - whether the body of the symbols should be editable

Returns:

this builder

bodyScaleRange

public TLspAPP6ALayerBuilder bodyScaleRange(ILcdInterval aBodyScaleRange)

Sets the scale range for the body of the symbols.

Parameters:

aBodyScaleRange - the scale range for the body of the symbols

Returns:

this builder

bodyMapScaleRange

public TLspAPP6ALayerBuilder bodyMapScaleRange(TLcdDimensionInterval<TLcdMapScale> aBodyScaleRange)

Sets the scale range for the body of the layer in unitless map scale ratios. This property defines a range of scales in which the bodies of the layer are visible. By default, no scale range is used, meaning that all bodies are visible.

Parameters:

aBodyScaleRange - the scale range for the body of the layer

Returns:

this

Since:

2021.0

culling

public TLspAPP6ALayerBuilder culling(boolean aUseCulling)

Sets whether objects outside the visible view portion are culled and not painted.

Enabling culling restricts the objects that are painted to those that (approximately) overlap with the view. This typically reduces the memory usage and increases the frame rate. However because culling also introduces an additional overhead, you may get better performance by disabling it for either very dynamic layers or layers with only a small amount of objects.

Parameters:

aUseCulling - whether the layer should use culling or not

Returns:

this builder

filter

public TLspAPP6ALayerBuilder filter(ILcdDynamicFilter aFilter)

Sets a filter that will be used to filter objects to prevent them from being painted by the layer. No filter is set by default.

Parameters:

aFilter - the filter

Returns:

this

icon

public TLspAPP6ALayerBuilder icon(ILcdIcon aIcon)

Description copied from class: ALspLayerBuilder

Sets the icon of the layer.

The default value is null.

Overrides:

icon in class ALspLayerBuilder

Parameters:

aIcon - the icon

Returns:

ILcdLayer.getIcon()

layerStyle

public TLspAPP6ALayerBuilder layerStyle(TLspLayerStyle aLayerStyle)

Description copied from class: ALspLayerBuilder

Set a layer style to be used during the rendering of the layer. TLspLayerStyle is used to style the layer as a whole. Layer style can for example modify the transparency of a layer. Also, layer style can be modified after building the layer by calling ILspLayer.setLayerStyle(TLspLayerStyle).

Overrides:

layerStyle in class ALspLayerBuilder

Parameters:

aLayerStyle - the layer style. Must not be null. If you want to set the default layer style, set TLspLayerStyle.newBuilder().build()

Returns:

this

Parameters:

aLabelScaleRange - the scale range for the labels of the symbols. If aLabelScaleRange is null, labels will always be displayed.

Returns:

this builder

labelMapScaleRange

public TLspAPP6ALayerBuilder labelMapScaleRange(TLcdDimensionInterval<TLcdMapScale> aLabelScaleRange)

Sets the scale range for the labels of the layer in unitless map scale ratios. This property defines a range of scales in which the labels of the layer are visible. By default, no scale range is used, meaning that all labels are visible.

aLabelScaleRange - the scale range for the labels of the layer

Returns:

this

Since:

2021.0

model

public TLspAPP6ALayerBuilder model(ILcdModel aModel)

The default value is null.

Overrides:

model in class ALspLayerBuilder

Parameters:

aModel - a model

Returns:

this builder

See Also:

ILcdLayer.getModel()

selectable

public TLspAPP6ALayerBuilder selectable(boolean aSelectable)

Sets whether the symbols should be selectable.

Parameters:

aSelectable - whether the symbols should be selectable

Returns:

this builder

objectViewMargin

public TLspAPP6ALayerBuilder objectViewMargin(double aObjectViewMargin)

Sets the largest possible difference (in pixels) between an object's model bounds and its painted representation's bounds that should be taken into account.

This value is used when determining what objects are visible (if culling is enabled). It ensures, for example, that a model element is still painted if its visual representation falls inside the view, but its model bounds do not.

If for example view-sized icons are used to represent points on the map, the icon could be 16 by 16 pixels, whereas the object itself is a point, having a zero size. Depending on where the point is located in the icon, the required margin for this example can be up to 16 pixels.

The drawback of setting a too large value is a performance loss. The drawback of setting a too small value is that objects (e.g. icons) disappear when they are located partly outside the view.

You can also configure a maximum distance in meters.

The default value is 32.

Parameters:

aObjectViewMargin - the maximum difference (in pixels)

Returns:

this

objectWorldMargin

public TLspAPP6ALayerBuilder objectWorldMargin(double aObjectWorldMargin)

Sets the largest possible difference (in meters) between an object's model bounds and its painted representation's bounds that should be taken into account.

This value is used when determining what objects are visible (if culling is enabled). It ensures, for example, that a model element is still painted if its visual representation falls inside the view, but its model bounds do not.

If for example circles are used to represent points on the map, the circle could have a radius of 1km, whereas the object itself is a point, having a zero size. The required margin for this example is 1000 meters.

The drawback of setting a too large value is a performance loss. The drawback of setting a too small value is that objects (e.g. icons) disappear when they are located partly outside the view.

You can also configure a maximum distance in pixels.

The default value is 0.

Parameters:

aObjectWorldMargin - the maximum difference in meters

Returns:

this
