public class AttributeListImpl extends Object implements AttributeList
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This class implements a deprecated interface, {@link org.xml.sax.AttributeList AttributeList}; that interface has been replaced by {@link org.xml.sax.Attributes Attributes}, which is implemented in the {@link org.xml.sax.helpers.AttributesImpl AttributesImpl} helper class.
Default implementation for AttributeList.This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. See http://www.saxproject.org for further information.
AttributeList implements the deprecated SAX1 {@link org.xml.sax.AttributeList AttributeList} interface, and has been replaced by the new SAX2 {@link org.xml.sax.helpers.AttributesImpl AttributesImpl} interface.
This class provides a convenience implementation of the SAX {@link org.xml.sax.AttributeList AttributeList} interface. This implementation is useful both for SAX parser writers, who can use it to provide attributes to the application, and for SAX application writers, who can use it to create a persistent copy of an element's attribute specifications:
private AttributeList myatts; public void startElement (String name, AttributeList atts) { // create 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.
Since: SAX 1.0
Version: 2.0.1 (sax2r2)

This constructor is most useful for parser writers, who will use it to create a single, reusable attribute list that can be reset with the clear method between elements.

This constructor is most useful for application writers, who will use it to create a persistent copy of an existing attribute list.
Parameters: atts The attribute list to copy
See Also: DocumentHandler
This method is provided for SAX parser writers, to allow them to build up an attribute list incrementally before delivering it to the application.
Parameters: name The attribute name. type The attribute type ("NMTOKEN" for an enumeration). value The attribute value (must not be null).
See Also: AttributeListImpl DocumentHandler
SAX parser writers can use this method to reset the attribute list between DocumentHandler.startElement events. Normally, it will make sense to reuse the same AttributeListImpl object rather than allocating a new one each time.
See Also: DocumentHandler
Returns: The number of attributes in the list.
See Also: AttributeList
Parameters: i The position of the attribute in the list.
Returns: The attribute name as a string, or null if there is no attribute at that position.
See Also: AttributeList
Parameters: i The position of the attribute in the list.
Returns: The attribute type as a string ("NMTOKEN" for an enumeration, and "CDATA" if no declaration was read), or null if there is no attribute at that position.
See Also: AttributeList
Parameters: name The attribute name.
Returns: The attribute type as a string ("NMTOKEN" for an enumeration, and "CDATA" if no declaration was read).
See Also: AttributeList
Parameters: i The position of the attribute in the list.
Returns: The attribute value as a string, or null if there is no attribute at that position.
See Also: AttributeList
Parameters: name The attribute name.

SAX application writers can use this method to filter an attribute out of an AttributeList. Note that invoking this method will change the length of the attribute list and some of the attribute's indices.
If the requested attribute is not in the list, this is a no-op.
Parameters: name The attribute name.
See Also: AttributeListImpl
This method allows an application writer to reuse an attribute list easily.
Parameters: atts The attribute list to copy.
