KeyValueStore

Persistent indexed key-value store, backed by an SQLite database. Non-string keys/values are JSON-encoded.

struct KeyValueStore (

K

V

) {

KeyValueDatabase* db;

string tableName;

this(KeyValueDatabase* db, string tableName);

this(string fn);

V opIndex(K k);

V get(K k, V defaultValue);

V require(K k, V defaultValue);

alias getOrAdd = require;

bool opBinaryRight(K k);

const(V) opIndexAssign(V v, K k);

void remove(K k);

int length [@property getter];

K[] keys [@property getter];

int opApply(int delegate(K key, V value) dg);

}

Constructors

this this(KeyValueDatabase* db, string tableName): Constructor with KeyValueDatabase and tableName. Allows using the same database file for multiple key/value tables.
this this(string fn): Constructor with file name. Creates a new KeyValueDatabase for private use.
