setOverwriteMode method
Sets overwrite mode mode
for write file operations during encryption
or decryption process.
Available modes:
AesCryptOwMode.warn - If the file exists, stops the operation and throws AesCryptException exception with AesCryptExceptionType.destFileExists type. This mode is set by default.
AesCryptOwMode.rename - If the file exists, adds index '(1)' to its' name and tries to save. If such file also exists, adds '(2)' to its name, then '(3)', etc.
AesCryptOwMode.on - Overwrite the file if it exists.
Implementation
void setOverwriteMode(AesCryptOwMode mode) => _owMode = mode;
