public class TLspVPFGeoSymLabelStyler extends ALspStyler
TLspVPFLayerBuilder
can be used to create fully configured layers
for a given VPF model.
This styler supports full and simplified GeoSym styling. When using full GeoSym styling the styling will be derived
from the fullsym.txt file, when configured to use simplified styling the simpsym.txt file is used.
The constructors of this class require a VPF product id as a parameter. This can be obtained from
TLcdVPFModelDescriptor
as follows:
TLcdVPFFeatureClass vpfFeatureClass = ((TLcdVPFModelDescriptor) aModel.getModelDescriptor()).getVPFFeatureClass(); String productId = vpfFeatureClass.getCoverage().getLibrary().getProductType();

public void style(Collection<?> aObjects, ALspStyleCollector aStyleCollector, TLspContext aContext)
ILspStyler
Styles the objects or labels contained in aObjects
using the methods provided
by ALspStyleCollector
.
Example usages for object styling:
// Same style for all objects:
aStyleCollector.objects(aObjects).style(myStyle).submit();
// Object specific styling:
aStyleCollector.object(myObject1).style(myStyle1).submit();
aStyleCollector.object(myObject2).style(myStyle2).submit();
Example usages for label styling:
if (aStyleCollector instanceof ALspLabelStyleCollector) {
ALspLabelStyleCollector labelStyleCollector = (ALspLabelStyleCollector)aStyleCollector;
// Specify a priority for all labels of all objects:
labelStyleCollector.objects(aDomainObjects).allLabels().priority(3).styles(...).submit();
// Specify an algorithm for a specific label:
labelStyleCollector.object(myObject1).label(123).algorithm(...).styles(...).submit();
}
The objects that are provided to aStyleCollector
must be objects that are contained in
aObjects
. Note that not all objects have to be styled. Objects that are not submitted in
aStyleCollector
will not be painted.
This method can be called very frequently, depending on the (amount of) data. If this method is not implemented efficiently, painting performance may be affected.
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.
