BinaryTable is used to translate a FITS binary table to a Casacore Table.
Public interface
BinaryTable inherits from the FITS BinaryTableExtension class and its primary use is to convert that class to a Casacore Table. This explains it's use but not its name. A better name should be found.
The class starts with an already existing FitsInput object, which should be set at a BinaryTableExtension HDU. Member functions provide a TableDesc appropriate for the FITS data (to help in constructing a Casacore Table compatible with the BinaryTableExtension), a Table containing the current row of FITS data and a Table containing the next row of FITS data (which can be used to step through the FitsInput, copying each row using the RowCopier class), and a Table containin the entire FITS binary table from the current row to the end of the table.
We need a way to get FITS data into Casacore Tables.
open a FitsInput from a disk file, if the HDU is a BinaryTableExtension, then instantiate a BinTable object and get the entire table. A fair amount of error checking has been eliminated from this example.
There would obviously be other cases to the switch to deal with any other HDUs (e.g. skip them via infits.skip_hdu()). The Table destructor would write "myTable" to disk.

FITSErrorHandler | errhandler = FITSError::defaultHandler , |
||
Bool | useMiriadSM = False , |
||
Bool | sdfits = False |
||
) |
The only constructor is from a FitsInput, you can also optionally provide a FITS error handler.
If useMiriadSM is True, use the Miriad storage manager for all columns, otherwise AipsIO. If sdfits is True, all non-reserved and some reserved keyword are treated as if they were columns with constant values "virtual columns" in the sdfits convention.

Table casacore::BinaryTable::fullTable | ( | const String & | tabName, |
const Table::TableOption | = Table::NewNoReplace , |

Bool | useMiriadSM = False |

Get the full table, using the supplied arguments to construct the table.
The table will contain all data from the current row to the end of the BinarTableExtension.If useMiriadSM is True, use the Miriad storage manager for all columns, otherwise AipsIO.
const TableDesc& casacore::BinaryTable::getDescriptor | ( | ) |
TableRecord& casacore::BinaryTable::getKeywords | ( | ) |
Return the Table keywords (this is the same TableRecord used in any Table objects returned by this class.
const Table& casacore::BinaryTable::nextRow | ( | ) |
const Table& casacore::BinaryTable::thisRow | ( | ) |
Get a Table with a single row, the current row of the FITS table.
The returned Table is a Scratch table. The standard BinaryTableExtension manipulation functions are available to position the FITS input at the desired location.
This is a map from column number to column name.
