Examples of org.xml.sax.helpers.AttributeListImpl

org.xml.sax.helpers.AttributeListImpl
te a persistent copy of the attribute list // for use outside this method myatts = new AttributeListImpl(atts); [...] }
Please note that SAX parsers are not required to use this class to provide an implementation of AttributeList; it is supplied only as an optional convenience. In particular, parser writers are encouraged to invent more efficient implementations.
@deprecated This class implements a deprecated interface,{@link org.xml.sax.AttributeList AttributeList}; that interface has been replaced by {@link org.xml.sax.Attributes Attributes}, which is implemented in the {@link org.xml.sax.helpers.AttributesImpl AttributesImpl} helper class. @since SAX 1.0 @author David Megginson, sax@megginson.com @version 2.0 @see org.xml.sax.AttributeList @see org.xml.sax.DocumentHandler#startElement
