runTime.write()
Posted April 4, 2017 at 09:42 by kindle
Code:
for (const_iterator iter = begin(); iter != end(); ++iter)
is replaced by
Code:
forAllConstIter(HashTable<regIOobject*>, *this, iter)
iterator is a built-in pointer of containers, here class objectRegistry inherates from regIOobject and more importantly has access to a table of IOobject.
In the above iteration, iteration is done for all object registried.
In the quoted code, iter() is a pointer pointing to IOobject and it calls writeOpt() using the ->.

regIOobject has got a fiunction called write() and a virtual function writeObject:
//- Write using given format, version and compression
virtual bool writeObject
(
IOstream::streamFormat fmt,
IOstream::versionNumber ver,
IOstream::compressionType cmp
) const;
//- Write using setting from DB
virtual bool write() const;
Clearly, write is just a wrapper around writeData. This one is over-ridden for objectRegistry and reads:
bool objectRegistry::writeObject
(
IOstream::streamFormat fmt,
IOstream::versionNumber ver,
IOstream::compressionType cmp
) const
{
bool ok = true;
for (const_iterator iter = begin(); iter != end(); ++iter)
{
if (objectRegistry::debug)
{
Pout<< "objectRegistry::write() : "
<< "Considering writing object "
<<>name()
<<>writeOpt()
<< endl;
if (iter()->writeOpt() != NO_WRITE)
{
ok = iter()->writeObject(fmt, ver, cmp) && ok;
}
}
return ok;
}}
Thus: loop over all objects registred in the object registry and offer them to write themselves. Each object will decide if it wants to do so, based on the settings, eg. NO_WRITE or AUTO_WRITE.
Clear?
