public final class AttributesImplSerializer
extends 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`
Usage:
  **For internal use only**

Constructor Summary
`AttributesImplSerializer()`

Method Summary
`void` | `addAttribute(java.lang.String uri, java.lang.String local, java.lang.String qname, java.lang.String type, java.lang.String val)` This method adds the attribute, but also records its qName/index pair in the hashtable for fast lookup by getIndex(qName).
`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(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).
