hi, i want to ask about how the listeners in java work.
if a class that i created, in this case DocInfo, implements IDocumentListener interface, and a DocumentEvent has occoured, could it be that before the current DocumentEvent has finished the documentChanged(DocumentEvent event) function another DocumentEvent will occour and activate the documentChanged(DocumentEvent event) function simultaneously?
here is the code below, thanks.
package handlevent.handlers;
import org.eclipse.jface.text.DocumentEvent;
import org.eclipse.jface.text.IDocumentListener;
public class DocInfo implements IDocumentListener{
@Override
public void documentAboutToBeChanged(DocumentEvent event) {
// TODO Auto-generated method stub
}
@Override
public void documentChanged(DocumentEvent event) {
// TODO Auto-generated method stub
System.out.println("document has been changed:");
System.out.println(event.getText());
}
}
