1. How to retrieve attributes from a hashtable:
/**
* Configuration attributes.
*/
protected Hashtable attributes = new Hashtable();
/**
* Return an array containing the names of all currently defined
* configuration attributes. If there are no such attributes, a zero
* length array is returned.
*/
public String[] getAttributeNames() {
Vector names = new Vector();
Enumeration keys = attributes.keys();
while (keys.hasMoreElements()) {
names.addElement((String) keys.nextElement());
}
String results[] = new String[names.size()];
for (int i = 0; i results[i] = (String) names.elementAt(i);
}
return (results);
}
/**
* Remove any configuration attribute associated with the specified name.
* If there is no such attribute, no action is taken.
*
* @param name Name of the attribute to remove
*/
public void removeAttribute(String name) {
attributes.remove(name);
}
