Constructor & Destructor Documentation

openvdb::OPENVDB_VERSION_NAME::io::MappedFile::~MappedFile

(

)

openvdb::OPENVDB_VERSION_NAME::io::MappedFile::MappedFile ( const MappedFile &  )

delete

Member Function Documentation

void openvdb::OPENVDB_VERSION_NAME::io::MappedFile::clearNotifier

(

)

Deregister the notifier.

SharedPtr<std::streambuf> openvdb::OPENVDB_VERSION_NAME::io::MappedFile::createBuffer

(

)

const

Return a new stream buffer for the mapped file.

Typical usage is

openvdb::io::MappedFile::Ptr mappedFile = ...;
auto buf = mappedFile->createBuffer();
std::istream istrm{buf.get()};
// Read from istrm...

The buffer must persist as long as the stream is open.

std::string openvdb::OPENVDB_VERSION_NAME::io::MappedFile::filename

(

)

const

Return the filename of the mapped file.

MappedFile& openvdb::OPENVDB_VERSION_NAME::io::MappedFile::operator= ( const MappedFile &  )

delete

void openvdb::OPENVDB_VERSION_NAME::io::MappedFile::setNotifier

(

const Notifier &

)

Register a function that will be called with this file's name when the file is unmapped.
