org.apache.xerces.readers.UTF8Reader
| UTF8Reader | | final class UTF8Reader extends XMLEntityReader (Code) | | This is the primary reader used for UTF-8 encoded byte streams.
This reader processes requests from the scanners against the
underlying UTF-8 byte stream, avoiding when possible any up-front
transcoding. When the StringPool handle interfaces are used,
the information in the data stream will be added to the string
pool and lazy-evaluated until asked for.
We use the SymbolCache to match expected names (element types in
end tags) and walk the data structures of that class directly.
There is a significant amount of hand-inlining and some blatant
voilation of good object oriented programming rules, ignoring
boundaries of modularity, etc., in the name of good performance.
There are also some places where the code here frequently crashes
the SUN java runtime compiler (JIT) and the code here has been
carefully "crafted" to avoid those problems.
