Detailed Description

template<typename K, typename V, typename KSerialiser, typename VSerialiser>
class ccf::kv::TypedMap< K, V, KSerialiser, VSerialiser >

Defines the schema of a map accessed by a ccf::Tx, exposing associated types. This map is an unordered associative container of key-value pairs. Each key, if defined, is associated with a value, and can be used to efficiently lookup that value.

K defines the type of the Key which indexes each entry, while V is the type of the Value associated with a given Key. KSerialiser and VSerialiser determine how each K and V are serialised and deserialised, so they may be written to the ledger and replicated by the consensus algorithm. Note that equality is always evaluated on the serialised form; if unequal Ks produce the same serialisation, they will coincide within this map. Serialiser which leverages existing JSON serialisation is provided by CCF.
