oldRead()

void BasicIntersectionOfWalls::oldRead

(

std::istream &

is

)

Reads BasicIntersectionOfWalls from an old-style restart file.

read()

void BasicIntersectionOfWalls::read ( std::istream &  is )

overridevirtual

Reads BasicIntersectionOfWalls from a restart file.

Parameters

[in]

is

The input stream from which the BasicIntersectionOfWalls is read.

Reimplemented from BaseWall.

{
    BaseWall::read(is);
    std::string dummy;
    unsigned size;
    // read e.g. "numIntersectionOfWalls 2"
    is >> dummy >> size;
    for (unsigned i = 0; i < size; i++)
    {
        std::string type;
        // read e.g. "IntersectionOfWalls"
        is >> type;
        BaseWall* wall = getHandler()->createObject(type);
        wall->setHandler(getHandler());
        wall->read(is);
        walls_.push_back(wall);
        walls_.back()->setId(walls_.size());
    }
}

write()

void BasicIntersectionOfWalls::write ( std::ostream &  os ) const

overridevirtual

Writes the BasicIntersectionOfWalls to an output stream, usually a restart file.

Parameters

[in]

os

The output stream the BasicIntersectionOfWalls is written to.

Reimplemented from BaseWall.

{
    BaseWall::write(os);
    os << " numIntersectionOfWalls " << walls_.size();
    for (auto w : walls_)
    {
        os << " ";
        w->write(os);
    }
}
