SAX2

The org.xml.sax.helpers Package

The org.xml.sax.helpers package holds support classes, including vendor-neutral bootstrapping support and some support for the original SAX1 APIs. These classes are in a sense optional but are provided by all widely available implementations. They’re also required for conformance with Sun’s JAXP API.

The AttributeListImpl Interface

This SAX1 class is not used in SAX2; the AttributesImpl class is used instead.

For more information, refer to Section 5.2 in Chapter 5.

public class AttributeListImpl implements AttributeList {
    public AttributeListImpl();
    public AttributeListImpl(AttributeList original);
    // AttributeList (accessors only)
    public int getLength();
    public String getName(int index);
    public String getType(int index);
    public String getValue(int index);
    public String getType(String qName);
    public String getValue(String qName);
    // mutators
    public void setAttributeList(AttributeList original);
    public void addAttribute(String qName, String type, String value);
    public void removeAttribute(String qName);
    public void clear();
}

The AttributesImpl Class

This class can be a convenient way to snapshot attribute information using the copy constructor. Since the attributes provided by an event producer are only valid during the particular ContentHandler.startElement() call that provides them, applications may need such snapshots. The class also supports construction of arbitrary attribute sets for filtering or event production.
