long long Int64
Define the extra non-standard types used by Casacore (like proposed uSize, Size)
virtual void writeBlock(MultiFileInfo &info, Int64 blknr, const void *buffer)
Write a data block.
Class to combine multiple files in a single one.
Abstract base class to combine multiple files in a single one.
Helper class for MultiFileBase containing info per internal file.
virtual void reopenRW()
Reopen the underlying file for read/write access.
virtual void doAddFile(MultiFileInfo &)
Do the class-specific actions on adding a file.
virtual void writeHeader()
Write the header info.
virtual void extend(MultiFileInfo &info, Int64 lastblk)
Extend the virtual file to fit lastblk.
virtual void close()
Flush and close the file.
Class for unbuffered IO on a file.
virtual ~MultiFile()
The destructor flushes and closes the file.
Bool useODirect() const
Will O_DIRECT be used?
bool Bool
Define the standard types used by Casacore.
virtual void readBlock(MultiFileInfo &info, Int64 blknr, void *buffer)
Read a data block.
virtual void doDeleteFile(MultiFileInfo &)
Do the class-specific actions on deleting a file.
Int64 blockSize() const
Get the block size used.
OpenOption
Define the possible ByteIO open options.
virtual void readHeader(Bool always=True)
Read the header info.
const vector< MultiFileInfo > & info() const
Get the info object (for test purposes mainly).
virtual void flushFile()
Flush the file itself.
String: the storage and methods of handling collections of characters.
virtual void fsync()
Fsync the file (i.e., force the data to be physically written).
this file contains all the compiler specific defines
MultiFile(const String &name, ByteIO::OpenOption, Int blockSize=0, Bool useODirect=False)
Open or create a MultiFile with the given name.
