protected abstract void processFeature(org.opengis.feature.simple.SimpleFeature feature, java.util.Map<java.lang.String,java.lang.Object> input) throws java.lang.Exception
This method should do some work based on the feature and then set any attributes on the feature as necessary. Example of a simple buffering operation:
protected void processFeature(SimpleFeature feature, Mapinput) throws Exception { Double buffer = (Double) input.get( BufferFeatureCollectionFactory.BUFFER.key ); Geometry g = (Geometry) feature.getDefaultGeometry(); g = g.buffer( buffer ); feature.setDefaultGeometry( g ); }
feature
- the feature being processedinput
- a Map of input parameters
java.lang.Exception
