OpenJUMP
Beanshell:Scripts for Roadmatcher

Hi Chris:

BeanShell can be the same as Java. But it also allows shortcuts, most notably: omitting the type declaration. Example:

    String x = "Hello World";

is the same as:

    x = "Hello World";

Here’s how to change all the TRIM segment comments to ABC />

{   
  for (feature : wc.getLayerManager().getLayer("Network TRIM").getFeatureCollectionWrapper().getFeatures()) {
    feature.getRoadSegment().setComment("ABC");
  }
}

I’ve enclosed everything with { and } because I find that the BeanShell editor that JUMP uses sometimes freezes otherwise :-(

Here’s how to change all the TRIM segment comments to “Long Road” if the length > 2000:

{   
  for (feature : wc.getLayerManager().getLayer("Network TRIM").getFeatureCollectionWrapper().getFeatures()) {
    if (feature.getRoadSegment().getApparentLineLength() <= 2000) { continue; }
    feature.getRoadSegment().setComment("Long Road");
  }
}

Note the use of the “enhanced for loop” – a Java 1.5 thing, but BeanShell lets you use it in any version of Java :-)

OK time for the issue log.

Here’s how to change all the issue log descriptions to Dell Axim X30 />

 
{   
  for (feature : wc.getLayerManager().getLayer("Issue Log").getFeatureCollectionWrapper().getFeatures()) {
    feature.setAttribute("Desc", "Dell Axim X30");
  }
}

Hope that helps!
