Class AttributeListImpl

Table des matières
  • All Implemented Interfaces:
    AttributeList
    Deprecated. 
    This class implements a deprecated interface, AttributeList; that interface has been replaced by Attributes, which is implemented in the AttributesImpl helper class.

    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    AttributeList implements the deprecated SAX1 AttributeList interface, and has been replaced by the new SAX2 AttributesImpl interface.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:
    SAX 1.0
    See Also:
    AttributeList, DocumentHandler.startElement(java.lang.String, org.xml.sax.AttributeList)

    • Method Detail

      • 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.

      • 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:
        addAttribute(java.lang.String, java.lang.String, java.lang.String)

      • 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.

        See Also:
        DocumentHandler.startElement(java.lang.String, org.xml.sax.AttributeList)

      • getName

        public String getName(int i)
        Deprecated. 
        Get the name of an attribute (by position).
        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.
        See Also:
        AttributeList.getName(int)

      • 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:
        AttributeList.getType(int)

      • 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:
        AttributeList.getValue(int)
