LazedAssocArray

Lazed Associative Array

For instance; assocArray["key"] = new ValueType The above code create a new instance of ValueType with some consts(memory amount and time). However it likely to be a bobottleneck if the value isn't needed. Then this class provides lazed associative array, this class willn't create an instance until the value become needed. In other words, this is sort of lazy evaluation for performance.

bool[string] called;

has bool has(string key): Undocumented in source. Be warned that the author may not have intended to support it.
insert void insert(): This function works like: // laa is an instance of LazedAssocArray laa["key"] = new T; with following way: laa.insert!("key", "new T");
insert void insert(): Undocumented in source. Be warned that the author may not have intended to support it.
insert void insert(): Undocumented in source. Be warned that the author may not have intended to support it.
insert void insert(string key, T delegate() value, bool always): Undocumented in source. Be warned that the author may not have intended to support it.
insert void insert(string key, T function() value, bool always): Undocumented in source. Be warned that the author may not have intended to support it.
link void link(string alternative, string key): Make an alias of the key
opIndex T opIndex(string key): An overloaded function of opIndex This function hooks: laa["key"] event.
opIndexAssing T opIndexAssing(T value, string key): An overloaded function of opIndexAssing This function hooks: laa["key"] = value; event but this function might be no use
set void set(string key, T value): Set the value with the key. This function works like: laa["key"] = value; with laa.set("key", value)
setupAll void setupAll(): Undocumented in source. Be warned that the author may not have intended to support it.
setupWith void setupWith(string name): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

alwaysNew bool[string] alwaysNew;: Undocumented in source.
called bool[string] called;: Flags, indicates whether the instance of the key is already created
constructors T delegate()[string] constructors;: This variable holds the constructor calling delegate to make the instance which will be called when the isntance become needed.
storage T[string] storage;: This variable holds the instance as a value of hashmap.
