- the zero::null and one::null sub-classes add an additional null
output adapter.
The function of the nil class (special-purpose class only used for
HashSet) is now taken by zero::null.
- consistent with C++ STL conventions, the reverse iterators should
use operator++ to transit the list from rbegin() to rend().
The previous implementation used raw pointers, which meant that they
had the opposite behaviour: operator-- to transit from rbegin() to
rend().
The updated version only has operator++ defined, thus the compiler
should catch any possible instances where people were using the old
(incorrect) versions.
- updated forAllReverseIters() and forAllConstReverseIters() macros to
be consistent with new implementation and with C++ STL conventions.
- The problem occurs when using atof to parse values such as "1e-39"
since this is out of range for a float and _can_ set errno to
ERANGE.
Similar to parsing of integers, now parse with the longest floating
point representation "long double" via strtold (guaranteed to be
part of C++11) and verify against the respective VGREAT values for
overflow. Treat anything smaller than VSMALL to be zero.
- reduce coding clutter, avoiding allocated pointers when possible.
IFstream and OFstream continue to use pointers since they handle
compressed files, other streams can do without them.
- these provide a similar functionality to string-streams, but operate
on a externally provided memory buffer which can be used to reduce
the amount of copying.
- classes were previously staged as part of the ADIOS community
repository.
- for convenience and symmetry with OStringStream
STYLE: void return value for stream rewind() methods
- this makes it easier to design bidirectional streams
- low-level beginRaw(), writeRaw(), endRaw() methods.
These can be used to directly add '()' decorators for serial output
or prepare/cleanup parallel buffers.
Used, for example, when outputting indirect lists in binary to avoid.
- used in various places to test if the input can be parsed as a
label/scalar, so warnings tend to flood the output.
- be more explicit when encountering range errors
