C++ (Cpp) FromData Examples

Example #1

File: Id.cpp Project: quyse/oil

Derived Id<n, Derived>::FromFile(ptr<File> file)
{
	if(file->GetSize() != size)
		THROW(String("Wrong size of id file for ") + typeid(Derived).name());

	return FromData(file->GetData());
}

Example #2

File: bip39.cpp Project: prapun77/monoeci

SecureString CMnemonic::Generate(int strength)
{
    if (strength % 32 || strength < 128 || strength > 256) {
        return SecureString();
    }
    SecureVector data(32);
    GetRandBytes(&data[0], 32);
    SecureString mnemonic = FromData(data, strength / 8);
    return mnemonic;
}

Example #3

File: nsSubstring.cpp Project: matyapiro31/instantbird-1.5

nsStringBuffer*
nsStringBuffer::FromString(const nsACString& str)
  {
    const nsACStringAccessor* accessor =
        static_cast<const nsACStringAccessor*>(&str);

    if (!(accessor->flags() & nsCSubstring::F_SHARED))

    return FromData(accessor->data());
  }
