- changed ensightOutput from a class solely comprising static methods to
a namespace and added in sub-namespaces Detail and Serial.
This makes it easier to "mix-in" functions at different levels.
Refactored and combined some serial/parallel code where possible.
The general ensightOutput namespace has now shifted to be in the
fileFormats lib, while leaving volField outputs in the conversion lib
and cloud outputs in the lagrangian-intermediate lib.
The ensightCloud namespace is now simply folded into the new
ensightOutput namespace.
These changes clean up some code, reduce fragmentation and
duplication and removes the previous libconversion dependency for
sampling.
- use int for ensight nTypes constexpr
Note: issue #1176 is unaffected except for the change in file name:
ensightOutputTemplates.C -> ensightOutputVolFieldTemplates.C
- align input parameters and some of the behaviour with vtkWrite
The output is now postProcessing/<name> for similar reasoning as
mentioned in #866 - better alignment with other function objects, no
data collision with foamToEnsight output.
- separate controls for internal and boundary meshes
- can restrict conversion based on zone names, enclosing volumes,
bounding box.
- more dictionary-like methods, enforce keyType::LITERAL for all
lookups to avoid any spurious keyword matching.
- new readEntry, readIfPresent methods
- The get() method replaces the now deprecate lookup() method.
- Deprecate lookupOrFailsafe()
Failsafe behaviour is now an optional parameter for lookupOrDefault,
which makes it easier to tailor behaviour at runtime.
- output of the names is now always flatted without line-breaks.
Thus,
os << flatOutput(someEnumNames.names()) << nl;
os << someEnumNames << nl;
both generate the same output.
- Constructor now uses C-string (const char*) directly instead of
Foam::word in its initializer_list.
- Remove special enum + initializer_list constructor form since
it can create unbounded lookup indices.
- Removd old hasEnum, hasName forms that were provided during initial
transition from NamedEnum.
- Added static_assert on Enum contents to restrict to enum or
integral values. Should not likely be using this class to enumerate
other things since it internally uses an 'int' for its values.
Changed volumeType accordingly to enumerate on its type (enum),
not the class itself.
New name: findObject(), cfindObject()
Old name: lookupObjectPtr()
Return a const pointer or nullptr on failure.
New name: findObject()
Old name: --
Return a non-const pointer or nullptr on failure.
New name: getObjectPtr()
Old name: lookupObjectRefPtr()
Return a non-const pointer or nullptr on failure.
Can be called on a const object and it will perform a
const_cast.
- use these updated names and functionality in more places
NB: The older methods names are deprecated, but continue to be defined.
- same as !isPattern(), but can be more readable.
- add wordRe enum state 'UNKNOWN', which has the identical value as
'DETECT' but used for a return value.
- for larger problems with a smaller region of interest, can apply a
bounding to limit the size of the ensight geometry and fields created.
Since the implementation uses a fvMeshSubset, there is an additional
per-process memory overhead.
A high output frequency should be avoided with moving meshes, since
this indirectly forces a frequent update of the submesh.
- The iterator for a HashSet dereferences directly to its key.
- Eg,
for (const label patchi : patchSet)
{
...
}
vs.
forAllConstIter(labelHashSet, patchSet, iter)
{
const label patchi = iter.key();
...
}
- IOstreamOption class to encapsulate format, compression, version.
This is ordered to avoid internal padding in the structure, which
reduces several bytes of memory overhead for stream objects
and other things using this combination of data.
Byte-sizes:
old IOstream:48 PstreamBuffers:88 Time:928
new IOstream:24 PstreamBuffers:72 Time:904
====
STYLE: remove support for deprecated uncompressed/compressed selectors
In older versions, the system/controlDict used these types of
specifications:
writeCompression uncompressed;
writeCompression compressed;
As of DEC-2009, these were deprecated in favour of using normal switch
names:
writeCompression true;
writeCompression false;
writeCompression on;
writeCompression off;
Now removed these deprecated names and treat like any other unknown
input and issue a warning. Eg,
Unknown compression specifier 'compressed', assuming no compression
====
STYLE: provide Enum of stream format names (ascii, binary)
====
COMP: fixed incorrect IFstream construct in FIREMeshReader
- spurious bool argument (presumably meant as uncompressed) was being
implicitly converted to a versionNumber. Now caught by making
IOstreamOption::versionNumber constructor explicit.
- bad version specifier in changeDictionary
Improve alignment of its behaviour with std::unique_ptr
- element_type typedef
- release() method - identical to ptr() method
- get() method to get the pointer without checking and without releasing it.
- operator*() for dereferencing
Method name changes
- renamed rawPtr() to get()
- renamed rawRef() to ref(), removed unused const version.
Removed methods/operators
- assignment from a raw pointer was deleted (was rarely used).
Can be convenient, but uncontrolled and potentially unsafe.
Do allow assignment from a literal nullptr though, since this
can never leak (and also corresponds to the unique_ptr API).
Additional methods
- clone() method: forwards to the clone() method of the underlying
data object with argument forwarding.
- reset(autoPtr&&) as an alternative to operator=(autoPtr&&)
STYLE: avoid implicit conversion from autoPtr to object type in many places
- existing implementation has the following:
operator const T&() const { return operator*(); }
which means that the following code works:
autoPtr<mapPolyMesh> map = ...;
updateMesh(*map); // OK: explicit dereferencing
updateMesh(map()); // OK: explicit dereferencing
updateMesh(map); // OK: implicit dereferencing
for clarity it may preferable to avoid the implicit dereferencing
- prefer operator* to operator() when deferenced a return value
so it is clearer that a pointer is involve and not a function call
etc Eg, return *meshPtr_; vs. return meshPtr_();
- disable automatically upgrading copyrights in files since changes to
not automatically imply a change in copyright. Eg, fixing a typo in
comments, or changing a variable from 'loopI' to 'loopi' etc.
- make construct from UList explicit and provide corresponding
assignment operator.
- add construct,insert,set,assignment from FixedList.
This is convenient when dealing with things like edges or triFaces.
