net.simplace.processors.FeatureCollectionCreatorProcessor

Version: 1.0

This processor creates a new or extends an existing org.geotools.feature.FeatureCollection. It is abstract because the geometry type of the org.geotools.feature.FeatureCollection and so the specification of one geometry via the input parameters is implemented in a sub-class (e.g. PointFeatureCollectionCreatorProcessor).
Required input parameters:

Key featureCollectionParamKey: key where to find the org.geotools.feature.FeatureCollection to extend with a new Feature. If no org.geotools.feature.FeatureCollection exists under the given key, a new one is created and stored under the key. Also a de.schmitzm.geotools.styling.StyledFeatureCollectionInterface is allowed.
Key forceNewCollection (optional): If true a new FeatureCollection is also created if featureCollectionParamKey already contains a FeatureCollection.
Key attrValue.: Value of attribute colName for the new Feature.
Key geomCRS: WKT specification or EPSG code of the CRS, which is used for the new feature's geometry. This parameter is only necessary if a new org.geotools.feature.FeatureCollection is created.
