- this provides a better typesafe means of locating predefined cell
models than relying on strings. The lookup is now ptr() or ref()
directly. The lookup functions behave like on-demand singletons when
loading "etc/cellModels".
Functionality is now located entirely in cellModel but a forwarding
version of cellModeller is provided for API (but not ABI) compatibility
with older existing user code.
STYLE: use constexpr for cellMatcher constants
- warn or fatal if Pstream::init or Pstream::exit are called multiple
times.
- additional Pstream::initNull method as failsafe to initialize MPI
when the underlying OpenFOAM process is not running in parallel but
the application still needs MPI.
- Pstream::exit() can now also be called without having used MPI::init(),
which means it can be used to cleanup serial process or for
applications that used the special purpose Pstream::initNull()
mechanism.
- allows changing the format of the sending OPstream at an arbitrary
point in the transmission. The information is passed through the
buffer and the receiving IPstream changes its format accordingly.
This allows a temporary toggling of ASCII/BINARY mid-stream.
- the return value signals if this method handled this particular type
of token. This minor change allows this method to be used as a succinct
prefilter an output token stream. It also provides better encapsulation
of what the particular output stream handles.
Eg,
bool ok = os.write(tok);
if (!ok) // or if (!ok && os.good())
{
os << tok;
}
instead of
if (tok.type() == typeA || tok.type() == typeB || ...)
{
os.write(tok);
}
else
{
os << tok;
}
- when dictionary keywords change between versions, the programmer
can use these compatibility methods to help with migration.
* csearchCompat, foundCompat, lookupEntryPtrCompat, lookupEntryCompat,
lookupCompat, lookupOrDefaultCompat, readIfPresentCompat, ...
They behave like their similarly named base versions, but accept an
additional list of older keyword names augmented by a version number.
For example,
dict.readIfPresentCompat
(
"key", {{"olderName", 1612}, {"veryOld", 240}},
myscalar
);
where 1612=OpenFOAM-v1612, 240=OpenFOAM-v2.4.x, etc.
- If the entry could be directly inserted: a pointer to the inserted entry.
- If a dictionary merge was required: a pointer to the dictionary that
received the entry.
- Return nullptr on any type of insertion failure.
This change is code compatible with existing code since it only alters
a bool return value to be a pointer return value.
- improved memory alignment reduces overhead for Int32 compilation
- added move/swap semantics
- made the type() readonly in favour of setVariant() to allow change
of variant within a particular storage representation.
Eg, STRING -> VERBATIMSTRING.
When specifying the averaging data, a new `windowType` option is
available, taking the values:
- none: no windowing
- approximate: past functionality (v1706 and earlier)
- exact: exact moving average - will store and write (for restart) all
fields in the window
- avoid meshModifier contents from being read immediately upon
construction, since this recreates an existing modifier instead of
allowing us to specify our own.
- 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.
