AttributeListImpl attributes = new AttributeListImpl();
Based on 13 examples
public class AttributeListImpl extends Object implements AttributeList
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AttributeList implements the deprecated SAX1 {@link org.xml.sax.AttributeList AttributeList} interface, and has been replaced by the new SAX2 {@link org.xml.sax.helpers.AttributesImpl AttributesImpl} interface.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.

Constructor Detail |
---|
public AttributeListImpl()
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.
public AttributeListImpl(AttributeList atts)
This constructor is most useful for application writers, who will use it to create a persistent copy of an existing attribute list.
atts
- The attribute list to copyMethod Detail |
---|
public void addAttribute(String name, String type, String value)
This method is provided for SAX parser writers, to allow them to build up an attribute list incrementally before delivering it to the application.
name
- The attribute name.type
- The attribute type ("NMTOKEN" for an enumeration).value
- The attribute value (must not be null).public void clear()
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.
public int getLength()
public String getName(int i)
i
- The position of the attribute in the list.public String getType(int i)
i
- The position of the attribute in the list.public String getType(String name)
name
- The attribute name.public String getValue(int i)
i
- The position of the attribute in the list.public String getValue(String name)
name
- The attribute name.public void removeAttribute(String 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.
name
- The attribute name.public void setAttributeList(AttributeList atts)
This method allows an application writer to reuse an attribute list easily.
atts
- The attribute list to copy.
