org.apache.xml.serializer.AttributesImplSerializer
public 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.
static int | 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(String uri, String local, String qname, String type, 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(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).

MAX
public static final int MAX
This is the number of attributes before switching to the hash table,
and can be tuned, but 12 seems good for now - bjm
addAttribute
public void addAttribute(String uri,
String local,
String qname,
String type,
String val)
This method adds the attribute, but also records its qName/index pair in
the hashtable for fast lookup by getIndex(qName).
uri
- the URI of the attributelocal
- the local name of the attributeqname
- the qualified name of the attributetype
- the type of the attributeval
- the value of the attribute
org.xml.sax.helpers.AttributesImpl.addAttribute(String, String, String, String, String)
, getIndex(String)
clear
public void clear()
This method clears the accumulated attributes.
org.xml.sax.helpers.AttributesImpl.clear()
getIndex
public int getIndex(String qname)
This method gets the index of an attribute given its qName.
qname
- the qualified name of the attribute, e.g. "prefix1:locName1"
- the integer index of the attribute.
org.xml.sax.Attributes.getIndex(String)
setAttributes
public 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).
atts
- the attributes to copy into these attributes.
