Examples of org.opengis.filter.FilterFactory2.touches()

org.opengis.filter.FilterFactory2.touches()
Checks if the feature's geometry touches, but does not overlap with the geometry held by this object.

  private FeatureIterator<SimpleFeature> getAffectedFeatures(SimpleFeature feature) throws IOException {
    FilterFactory2 filterFactory = CommonFactoryFinder.getFilterFactory2(GeoTools.getDefaultHints());
    String geomAttName = feature.getFeatureType().getGeometryDescriptor().getLocalName();
    PropertyName geomPropertyExpression = filterFactory.property(geomAttName);
    Literal literalGeomExpression = filterFactory.literal(feature.getDefaultGeometry());
    Touches filter = filterFactory.touches(geomPropertyExpression, literalGeomExpression);
    
    IProgressMonitor monitor = 
      getContext().getActionBars().getStatusLineManager().getProgressMonitor();
