org.apache.myfaces.view.facelets.StateWriter
A class for handling state insertion. Content is written directly to "out" until an attempt to write state; at that point, it's redirected into a buffer that can be picked through in theory, this buffer should be very small, since it only needs to be enough to contain all the content after the close of the first (and, hopefully, only) form.
Potential optimizations:
- If we created a new FastWriter at each call to writingState(), and stored a List of them, then we'd know that state tokens could only possibly be near the start of each buffer (and might not be there at all). (There might be a close-element before the state token). Then, we'd only need to check the start of the buffer for the state token; if it's there, write out the real state, then blast the rest of the buffer out. This wouldn't even require toString(), which for large buffers is expensive. However, this optimization is only going to be especially meaningful for the multi-form case.
- More of a FastWriter optimization than a StateWriter, but: it is far faster to create a set of small 1K buffers than constantly reallocating one big buffer.
