示例1: getDataset
import org.eclipse.january.dataset.IDataset; //导入方法依赖的package包/类
@Override
public IDataset getDataset(IMonitor mon, SliceND slice) throws IOException {
if (loader == null) {
return null;
}
IDataHolder holder;
try {
holder = loader.loadFile(mon);
} catch (ScanFileHolderException e) {
throw new IOException("Could not load file", e);
}
if (holder.getFilePath() == null) {
holder.setFilePath(fileName);
}
if (holder.getLoaderClass() == null) {
holder.setLoaderClass(loader.getClass());
}

import org.eclipse.january.dataset.IDataset; //导入方法依赖的package包/类
protected void startReorderThread() {
updating = true;
final Thread doReordering = new Thread(new Runnable() {
public void run() {
while(updating) {

// Convenience method for thread safe update
// Could use IITmageTrace.setData(...) but must be from UI thread ie needing a syncExec
// or similar, therefore use convenience method
system.updatePlot2D(nimage, trace.getAxes(), new NullProgressMonitor());

} catch (InterruptedException e) {
e.printStackTrace();
}
}
}

// implementing parallel streams with Datasets but this was not available
// when these examples were being written.
