This provides support for tracking changes to mapping from prefixes to namespace URIs and vice versa.
Warning: This is a facade provided for use by user code, not for implementation by user code. User implementations of this interface are highly likely to be incompatible with future releases of the product at both binary and source levels.

This class is intended to be used within a SAX {@link org.xml.sax.ContentHandler} and relies on the order that theprefix mapping and element events are received in SAX. i.e. startPrefixMapping events are received before the associated startElement event and the endPrefixMapping events are received after the associated endElement event.

Most elements will not have any prefix mappings at all so implementations of this should be able to handle that efficiently both in terms of time and performance.

The methods are intended to be used as follows.

startElement

This should be called by the SAX ContentHandler startElement method.

endElement

This should be called by the SAX ContentHandler endElement method.

startPrefixMapping

This should be called by the SAX ContentHandler startPrefixMapping method.

endPrefixMapping

This should be called by the SAX ContentHandler endPrefixMapping method.

If a {@link QName} has an empty prefix then the mapping of the prefix tonamespace URI is dependent on what the {@link QName} is used for. If it isan element then it maps to the default namespace, if it is an attribute then it defaults to the empty namespace and if it is something else such as an XPath function name then it maps to the default function namespace.

Caveat

SAX specifically states that startPrefixMapping and endPrefixMapping events cannot be relied upon to be properly nested with respect to each other. The only thing that can be relied upon is that all the startPrefixMapping events are received before the corresponding startElement event and the endPrefixMapping events are received after the corresponding endElement event.

The events are only properly nested with respect to each other if the endPrefixMapping events are received in the reverse order to the order that the startPrefixMapping} events were received in.
```
 <E xmlns:A="ALPHA" xmlns:B="BETA" xmlns:C="GAMMA"> ... </E> 
```
Given the previous markup the first list shows one possible sequence of properly nested events and the second list shows one possible sequence of badly nested events.
1. startPrefixMapping(A, ALPHA)
2. startPrefixMapping(B, BETA)
3. startPrefixMapping(C, GAMMA)
4. startElement(E)
5. ...
6. endElement(E)
7. endPrefixMapping(C)
8. endPrefixMapping(B)
9. endPrefixMapping(A)
1. startPrefixMapping(A, ALPHA)
2. startPrefixMapping(B, BETA)
3. startPrefixMapping(C, GAMMA)
4. startElement(E)
5. ...
6. endElement(E)
7. endPrefixMapping(A)
8. endPrefixMapping(B)
9. endPrefixMapping(C)
If the events are not received in properly nested order then the mappings held by this object may be incorrect during the processing of endPrefixMapping events. The mappings will be correct once all the endPrefixMapping events for an element have been received.
