◆ getData()

Return the requested portion of the to-be-hashed data block.
Special requirement: it should be allowed to temporarily overwrite the byte one position before the returned pointer.

◆ isCacheStillValid()
|
inlineoverridevirtual |
Because TTH calculation of a large file takes some time (a few 1/10s for a hard disk image) we try to cache previous calculations.
This method makes sure we don't wrongly reuse the data. E.g. after it has been modified (by openmsx or even externally).
Note that the current implementation of the caching is only suited for files. Refactor this if we ever need some different.
