Package org.apache.xml.serializer

Class AttributesImplSerializer

  • All Implemented Interfaces:
    org.xml.sax.Attributes
    public final class AttributesImplSerializer
extends org.xml.sax.helpers.AttributesImpl
    This class extends org.xml.sax.helpers.AttributesImpl which implements org. xml.sax.Attributes. But for optimization this class adds a Hashtable for faster lookup of an index by qName, which is commonly done in the stream serializer.
    See Also:
    Attributes

      void clear()
      This method clears the accumulated attributes.
      int getIndex​(java.lang.String qname)
      This method gets the index of an attribute given its qName.
      int getIndex​(java.lang.String uri, java.lang.String localName)
      This method gets the index of an attribute given its uri and locanName.
      void setAttributes​(org.xml.sax.Attributes atts)
      This method sets the attributes, previous attributes are cleared, it also keeps the hashtable up to date for quick lookup via getIndex(qName).
