Hi!
If you just want to load shapefiles, you can use ShapefileReader directly to
load a shapefile into a FeatureCollection.
ShapefileReader reader = new ShapefileReader();
FeatureCollection features = reader.read(new
DriverProperties(shapefilePath));
Layer layer = context.getLayerManager().addLayer("Category Name", "Layer
Name", features);
DataSourceQuery: The monitor parameter is a TaskMonitor and used to report
progress and check cancel requests. Connection needs this TaskMonitor, so
you need to put the call into the run() method in the (threaded) PlugIn to
receive a monitor (public void run(TaskMonitor monitor, PlugInContext
context)).
If you don't want to use the run() / ThreadedPlugIn, you could maybe create
a com.vividsolutions.jump.task.DummyTaskMonitor and use it monitor instead?
(I didn't test this)
connection = dataSourceQuery.getDataSource().getConnection()
connection.executeQuery(query, exceptions, new DummyTaskMonitor())
----------
BTW: Maybe we should split LoadDatasetPlugIn into two PlugIns (I had this
idea a few weeks ago).
One called LoadDatasetPlugIn without dialog, which loads datasets into the
LayerManager.
LoadDatasetPlugIn datasetPlugIn = new LoadDatasetPlugIn();
datasetPlugIn.setFilepath("~/shapefiles/world.shp");
datasetPlugIn.setType("shapefile");
datasetPlugIn.setCategory("Category Name");
datasetPlugIn.setLayerName("Layer Name");
datasetPlugIn.execute();
Another called LoadDatasetsDialogPlugIn with a dialog, which shows a
JFileChooser and uses the LoadDatasetPlugIn.
With LoadDatasetPlugIn one can programmatically load datasets.
LoadDatasetsDialogPlugIn is used in the workbench (File > Open...).
