Arne Elster	fd66dda1d7	HexEditor: Stream input files instead of keeping them in memory ... To support editing of large files it is an advantage to not load the entire file into memory but only load whatever is needed for display at the moment. To make it work, file access is abstracted into a socalled HexDocument, of which there two: a memory based and a file based one. The former can be used for newly created documents, the latter for file based editing. Hex documents now do track changes instead of the HexEditor. HexEditor only sets new values. This frees HexEditor of some responsibility.	2021-12-23 23:25:47 -08:00
