The biggest offender is SAXAttributeList:
public int getLength ();
public String getName (int i);
public String getType (int i);
public String getValue (int i);
public String getType (String name);
public String getValue (String name);
To minimise method-name collisions, we would have to do something like
this:
public int getAttributeListLength ();
public String getAttributeName (int i);
public String getAttributeType (int i);
public String getAttributeValue (int i);
public String getAttributeType (String name);
public String getAttributeValue (String name);
The first, "getAttributeListLength", is the ugliest. It is simple to
avoid this problem by creating a separate class for SAXAttributeList,
rather than implementing it in the main driver -- what does everyone
else think about this question?
Thanks, and all the best,
