handleCorruption
This function will be called by DataStore when it encounters corruption. If the implementation of this function throws an exception, it will be propagated to the original call to DataStore. Otherwise, the returned data will be written to disk.
This function should not interact with any DataStore API - doing so can result in a deadlock.
Return
The value that DataStore should attempt to write to disk.
Parameters
ex
is the exception encountered when attempting to deserialize data from disk.
