-
The coding and design conventions (CDC) document was also updated.
-
GMWLDatum energy_err(), flux(), and flux_err() methods now return const references. GMWLObservation filename(), extno() and extname() methods now return const references. GMWLSpectrum telescope() and instrument() methods now return const references.
-
The abstract pointing class has been removed as so far no abstract pointing interface is needed.
-
GEvents GEventList The clobber argument of the save() method is now passed as const reference. GEventCube The clobber argument of the save() method and the axis argument of the naxis() method are now passed as const references.
-
The GFitsHeader class now derives from GContainer and implements all generic container class methods (at(), size(), isempty(), append(), insert(), remove(), reserve(), extend()). The hascard() methods have been renamed to contains() for compliance with other container classes. The card() methods have been renamed to at(), also for compliance. The card access operators and methods now return the cards by reference. Card access operators[] have been implemented to access header cards without range checking. The cards are now stored using a std::vector structure.
-
The GFits class now derives from GContainer and implements all generic container class methods (at(), size(), isempty(), set(), append(), insert(), remove(), reserve(), extend()). The hashdu() method has been renamed to contains() for compliance with other container classes. The hdu() methods have been renamed to at(), also for compliance. Boolean arguments are now passed as const references, and members are returned as const references. HDU access operators[] have been implemented to access FITS extensions without range checking.
-
A major revision of the GFitsTable class interface has been done, making it more similar to the interface of other container classes. In particular, the column access operator now returns a pointer instead of a reference, preventing code slicing. The set() method has been introduced to set columns in a table. The append_column() and insert_column() methods have been renamed to append() and insert() as they act on columns, and a table is a column container. Some arguments or return values are now also declared as const references. A size() method has been added that return the number of table columns. As the GFitsTable class is widely used throughout GammaLib, a number of classes had to be adapted to this new interface.
-
Before, the allocated memory was lost, leading to a memory leak. This should now be prevented.
-
Add GChatter argument to print() method. The print() method now takes an argument of type GChatter to control the chattiness of the output in a homogenous manner. Pass NORMAL chatter level in __str__ method. Add chatter argument to print() methods. Use GLog::chatter() method to control the chattiness of the log stream operator. Add chatter() methods and provide member access through const references. Add chatter() methods, provide member access through const references, and declare one liners as inline methods. The chatter() methods control the new m_chatter attribute that is used to control the chattiness of the object's print() methods. name() and version() methods return const references. logFileOpen() method now sets the chattiness from the applications's chatter parameter, and name() and version() methods now return a const reference.
-
As an observation container needs a unique observation identifier we build now the default identifier from the filename and the extension number.
-
The GTime interface has been reworked, and some adaption was needed. One of the main changes was the replacement of the met() method by the secs() method. The secs() method returns now the time in seconds in the native GammaLib time reference.
-
The c_str() return value is only valid until its string is delected. We thus have to use the tochar function of the toolbox to copy the c_str() return value into a string.
