Member Description

SDMSIterator(const String &msName, const Record &selection, Table::TableOption opt = Table::Old, TableLock::LockOption lockoptions = TableLock::DefaultLocking, Bool useCorrectedData = False)

SDMSIterator(const SDMSIterator& other)

construct from another MS iterator

SDMSIterator(const SDMSIterator& other, const Record &selection)

construct from another with selection

~SDMSIterator()

SDMSIterator &operator=(const SDMSIterator& other)

assiment operator

virtual String type() const

what type of sditerator is this ("MeasurementSet")

Bool unlock()

Unlock this table

Bool lock(uInt nattempts=0)

Lock this table. Try nattempts times.

void origin()

reset the iterator to the top

Bool more()

are there any more SDRecords after the current one

SDIterator& operator++(int)

step to the next one, if at end, nothing changes

SDIterator& operator++()

SDIterator& operator--(int)

step back, if at end, nothing changes

SDIterator& operator--()

uInt where() const

return the current row number

uInt nrecords()

how many SDRecords are there

void resync()

resync with the disk contents

void flush()

flush to disk - a no-op for read-only sditerators (all MS-based ones are read-only)

void reselect()

re-select

void deepCopy(const String &newName)

make a deep copy

const SDRecord &get()

return the current SDRecord

const Record &getData()

return just the data portion of the current SDRecord

const Record &getHeader()

return just the header portion of the current SDRecord

const Record &getOther()

return just the other portion of the current SDRecord

const Array<String> getHist()

return just the hist portion of the current SDRecord

Bool put(const SDRecord& rec)

replace the current SDRecord with a new one

Bool appendRec(const SDRecord &rec)

add a new record at the end of the iterator

Bool deleteRec()

delete the record at the current location

Bool isWritable() const

see if this iterator is writable currently always returns False.

const Record &stringFields() const

get a record with structure like the current working SDRecord which contains only fields which are scalar string fields - the value of those fields is just a boolean. This is necessary so that the proper parsing of the selection when given as a string can be done for each field without having to duplicate that code in both glish and here in C++.

String name() const

return the name of iterator, the same as the table name

Bool ok() const

other things may not work if ok == False, this needs to be cleaned up

virtual Bool useCorrectedData(Bool correctedData)

Toggle use of corrected data if available.

virtual Bool correctedData()

query whether corrected data is being used.
