Package com.sun.msv.verifier.regexp
VGM implementation by using regular expression derivation algorithm.
VGM implementation by using regular expression derivation algorithm.
This implementation bridges a gap between
neutral grammar model (com.sun.msv.grammar) and Verifier grammar
model (com.sun.msv.verifier).
Performance Analysis
This bridge is tuned for client-side use, where MSV is repeatedly
invoked from command line. Particularly,
-
No preprocessing of grammar is necessary. Abstract grammar model can
be directly used. This results in faster schema loading, at the expense of
slower validation.
-
Extensive error recovery and detailed error diagnosis is
provided.
Also, this bridge covers full expressiveness of RELAX and
TREX.
