| static IStorageBackend::String convertUniqueIDToHex | ( | const UniqueID & | key ) | [static] |
Turns a unique ID into a hex string that can be used as a key or as a value.
Definition at line 44 of file storage_marshaller.hpp.
| int get | ( | const IStorageBackend::String & | key, |
| uint32_t & | out_value | ||
| ) | const |
Getters simply read and deserialize the value.
1. Read the value back from the backend; return false if read fails. 2. Deserealize the newly read value; return false if deserialization fails. 3. Update the argument with deserialized value. 4. Return true.

| int setAndGetBack | ( | const IStorageBackend::String & | key, |
| uint32_t & | inout_value | ||
| ) |
These methods set the value and then immediately read it back.
1. Serialize the value. 2. Update the value on the backend. 3. Call get() with the same value argument. The caller then is supposed to check whether the argument has the desired value.
