Adios2StMan(std::string xmlFile, MPI_Comm mpiComm=MPI_COMM_WORLD)
virtual void create64(rownr_t aNrRows)
Let the data manager initialize itself for a new table.
static DataManager * makeObject(const String &aDataManType, const Record &spec)
virtual DataManager * clone() const
Make a clone of the derived object.
virtual DataManagerColumn * makeScalarColumn(const String &aName, int aDataType, const String &aDataTypeID)
Create a column in the data manager on behalf of a table column.
virtual void addRow64(rownr_t aNrRows)
Add rows to all columns.

virtual String dataManagerName() const
Return the name of the data manager.
virtual DataManagerColumn * makeDirArrColumn(const String &aName, int aDataType, const String &aDataTypeID)
Create a direct array column.
virtual DataManagerColumn * makeIndArrColumn(const String &aName, int aDataType, const String &aDataTypeID)
Create an indirect array column.
virtual String dataManagerType() const

virtual rownr_t open64(rownr_t aRowNr, AipsIO &ios)
Let the data manager initialize itself for an existing table.
Record dataManagerSpec() const
Return a record containing data manager specifications.
virtual void deleteManager()
The data manager will be deleted (because all its columns are requested to be deleted).
virtual rownr_t resync64(rownr_t aRowNr)
Resync the data by rereading cached data from the file.
Abstract base class for a data manager.
String: the storage and methods of handling collections of characters.
