First part of the refactoring of Parser.h/.cpp
First part of the refactoring of Parser.h/.cpp
- Removed the RewardMatrixInformationStruct since it was only used as function argument.
|- Replaced its function by the respective results of the transition parser (for det/non-det)
- Moved the MappedFile class to separate file.
- Renamed the SupportedFileEndingsEnum enum to SupportedFileEndings.
- Whats left in Parser.*:
|- A bunch of free functions for manipulation of c-style strings, a function to read the model hint and the SupportedFileEndings enum with its recognition function.
Im not exactly sure what to do with this.
- I think the name Parser.* implies a parser base class, while it is not. Therefore: Renaming.
- The c-style string manipulation functions might also needed elsewhere. Therefore: Moving them into the utility folder/namespace.
- The model hint function would fit in the AutoParser, except for its signature (low level arguments vs. high level arguments of the AutoParser). Therefore: Either moving it to the Auto Parser or leave it as helper function with the others (c-style string handling and low level OS detection)
- The SupportedLineEndings and its assorted functions either belong to the string manipulation functions or to the MappedFile class. Therefor: Moving them accordingly.
- Once all things have moved the Parser.* will be empty. Therefore: Deletion.
Next up: Trying to decide what to do with the rest of the Parser.* and doing it.
