I have a DocumentListener with 2 different JTextFields listening (as below).
How do I determine which component triggered a specific event?

DocumentListener documentListener = new DocumentListener() {
	
	public void changedUpdate(DocumentEvent documentEvent) {
		updateValue(documentEvent);
	}
	
	public void insertUpdate(DocumentEvent documentEvent) {
		updateValue(documentEvent);
	}
	
	public void removeUpdate(DocumentEvent documentEvent) {
		updateValue(documentEvent);
	}
	
	private void updateValue(DocumentEvent documentEvent) {
		
		Document source = documentEvent.getDocument();
		try {
			
		    String string = source.getText(0, source.getLength());

		} catch (BadLocationException e) {
		logger.error(e.toString());
	}

	}
};

textField1.getDocument().addDocumentListener(documentListener);
textField2.getDocument().addDocumentListener(documentListener);
