java.lang.Objectorg.xml.sax.helpers.AttributesImpl
org.apache.xml.serializer.AttributesImplSerializer
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.
Attributes

MAX
This is the number of attributes before switching to the hash table, and can be tuned, but 12 seems good for now - bjm |

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. |
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). |
