All Implemented Interfaces:

ILspCustomizableStyler, ILspStyler

public class TLspRulerLabelStyler
extends ALspLabelStyler
implements ILspCustomizableStyler

An default label styler for the TLspRulerController. When the domain object to style is an ALspRulerMeasurement, this styler will style a segment label for each line segment and a total distance label at the end of the entire polyline.

This class uses six customizable styles to style these labels:

• Three styles with identifier SEGMENT used for the individual segment labels, a TLspTextStyle, a TLspLabelBoxStyle and a TLspRulerSegmentLabelContentStyle.
• Three styles with identifier TOTAL used for the total distance label, a TLspTextStyle, a TLspLabelBoxStyle and a TLspRulerDistanceFormatStyle.

To adapt the styles, get them using getStyles(), and replace the style you want to change by another style. At least a TLspTextStyle and a ALspLabelTextProviderStyle must be present and active for (useful) labels to appear.

Since:

2012.0

Constructor Details

TLspRulerLabelStyler

public TLspRulerLabelStyler()

Creates a new TLspRulerLabelStyler with a default blue and white style for both segment and total labels. Both labels only contain the distance formatted in meters.

Method Details

style

public void style(Collection<?> aObjects,
 ALspStyleCollector aStyleCollector,
 TLspContext aContext)

Description copied from class: ALspLabelStyler

Implementation of ILspStyler.style that either casts the ALspStyleCollector to ALspLabelStyleCollector if possible, or adapts it otherwise. In the latter case, the labeling-specific calls (label, anchorLabel, algorithm, ...) are ignored. The ALspLabelStyleCollector is then passed to the style(Collection,ALspLabelStyleCollector,TLspContext) method.

Specified by:

style in interface ILspStyler

Overrides:

style in class ALspLabelStyler

Parameters:

aObjects - The objects to be styled.

aStyleCollector - A style collector to which all styling information should be passed, this collector is only valid within this method call, and can no longer be used afterwards.

aContext - Provides context information that may affect styling, such as view specific properties.

style

public void style(Collection<?> aObjects,
 ALspLabelStyleCollector aStyleCollector,
 TLspContext aContext)

Description copied from class: ALspLabelStyler

Convenience method that takes an ALspLabelStyleCollector as argument instead of an ALspStyleCollector. This method is called from ALspLabelStyler.style(Collection, ALspStyleCollector, TLspContext).

Specified by:

style in class ALspLabelStyler

Parameters:

aObjects - The set of domain objects to provide information for

aStyleCollector - The label style collector to submit the information to.

aContext - The context

• ALspLabelStyleCollector

getStyles

public Collection<TLspCustomizableStyle> getStyles()

Description copied from interface: ILspCustomizableStyler

Returns the styler's customizable styles. When modifications are made to the styles, the styler will automatically inform its listeners about the change. The following changes can be made:

• Styles can be enabled or disabled. Only the enabled styles will be set in the style method.
• The ALspStyle in the TLspCustomizableStyle may be replaced

The collection is not ordered, but you can use the identifier of the TLspCustomizableStyle to recognize and order the styles.

Specified by:

getStyles in interface ILspCustomizableStyler

Returns:

An immutable collection containing all styles which will be set in the style method
