Probably want '==' for that comparison.
This doesn't come close to compiling: first because makeStream is
const, you can't do the assignment. You have to make a local variable
and cast of the const-ness like:
BinMemInputStream *stream = new BinMemInputStream(...);
SuperFastMemBufInputSource *localThis =
const_cast<SuperFasMemBufInputSource *>(this);
localThis->fMemStream = stream;
But then, all those variables are private, you have to modify
MemBufInputSource.hpp to change them to protected.
However ...
Even after this, it doesn't have the desired affect. Calling curPos()
in the startElement() method prints the same position for every
element:
print Found element contributors at 377 offset
print Found element person at 377 offset
print Found element name at 377 offset
print Found element email at 377 offset
.
.
.
I modified it for LocalFileInputSource as well and got the same result:
print Found element personnel at 1186 offset
print Found element person at 1186 offset
print Found element name at 1186 offset
print Found element family at 1186 offset
.
.
.
And 1186 is the length of the file, so it looks like the
BinInputStream is taken the whole way to the end in both cases before
the Parser starts the callbacks.
Any ideas what to do?
