Class AttributeListImpl

java.lang.Object
org.xml.sax.helpers.AttributeListImpl
All Implemented Interfaces:
AttributeList
@Deprecated(since="1.5") public class AttributeListImpl extends Object implements AttributeList
Deprecated.
This class implements a deprecated interface, AttributeList; that interface has been replaced by Attributes, which is implemented in the AttributesImpl helper class.
Default implementation for AttributeList.

AttributeList implements the deprecated SAX1 AttributeList interface, and has been replaced by the new SAX2 AttributesImpl interface.

This class provides a convenience implementation of the SAX 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:
1.4, SAX 1.0

    • setAttributeList

      public void setAttributeList(AttributeList atts)
      Deprecated.
      Set the attribute list, discarding previous contents.

      This method allows an application writer to reuse an attribute list easily.

      Parameters:
      atts - The attribute list to copy.

    • addAttribute

      public void addAttribute(String name, String type, String value)
      Deprecated.
      Add an attribute to an attribute list.

      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:

    • removeAttribute

      public void removeAttribute(String name)
      Deprecated.
      Remove an attribute from the list.

      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:

    • clear

      public void clear()
      Deprecated.
      Clear the attribute list.

      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.

    • getLength

      public int getLength()
      Deprecated.
      Return the number of attributes in the list.

      Specified by:
      getName in interface 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.

    • getType

      public String getType(int i)
      Deprecated.
      Get the type of an attribute (by position).
      Specified by:
      getType in interface 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:

    • getValue

      public String getValue(int i)
      Deprecated.
      Get the value of an attribute (by position).
      Specified by:
      getValue in interface 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:

    • getType

      public String getType(String name)
      Deprecated.
      Get the type of an attribute (by name).
      Specified by:
      getType in interface AttributeList
      Parameters:
      name - The attribute name.
      Returns:
      The attribute type as a string ("NMTOKEN" for an enumeration, and "CDATA" if no declaration was read).
