There is in load-client.cc
In method BytesUtil::ToInt64 is:
int64_t BytesUtil::ToInt64(std::string str) {
if (str.length() < 8) {
throw std::runtime_error("There are not enough bytes. Expected: 8,
actual: " + str.length());
}
const unsigned char *bytes = reinterpret_cast<unsigned char
*>(const_cast<char *>(str.c_str()));
int64_t l = 0;
for (int i = 0; i < 8; i++) {
l <<= 8;
l ^= bytes[i];
}
return l;
}
This means that is possible retrieve any binary data from string,
including not utf-8 chars and \0 char ?
Similar, put->AddColumn(family, qualifier, value) can add any binary
data as value casting it to char?
In example simple-test.cc was error when trying put empty string.
