public abstract class ALspLabelStyler
extends ALspStyler

Abstract base class for label styler implementations.

This class provides convenience methods for handling style changes.

This class also implements the regular ILspStyler by adapting or casting the ALspStyleCollector to an ALspLabelStyleCollector.

Note that it is not necessary to use this class to implement a styler for labels. It is possible to use a regular ILspStyler implementation that casts the ALspStyleCollector instance that is passed to the ILspStyler#style method to ALspLabelStyleCollector.

Since:

2012.0

Method Detail

style

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

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.

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

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

Parameters:

aObjects - The set of domain objects to provide information for

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

aContext - The context
