ModelMap

ModelMap serves as an abstraction layer around associative arrays that store models. Usually ModelMaps will be a direct mapping of ID (Snowflake) -> Model.

class ModelMap (

TKey

TValue

) {

TValue[TKey] data;

TValue set(TKey key, TValue value);

TValue get(TKey key);

TValue get(TKey key, TValue def);

void remove(TKey key);

bool has(TKey key);

TValue opIndex(TKey key);

void opIndexAssign(TValue value, TKey key);

size_t length();

auto subset(TKey[] keysWanted);

auto filter(bool delegate(TKey, TValue) f);

auto filter(bool delegate(TValue) f);

auto each(void delegate(TValue) f);

TValue pick(bool delegate(TValue) f, TValue def = null);

auto keys();

auto values();

TKey[] keyUnion(TKey[] other);

Functions

each auto each(void delegate(TValue) f): Allows applying a delegate over the values of the mapping.
filter auto filter(bool delegate(TKey, TValue) f): Allows using a delegate to filter the keys/values of the mapping into a new mapping.
filter auto filter(bool delegate(TValue) f): Allows using a delegate to filter the values of the mapping.
get TValue get(TKey key): Return the value for a key. Throws an exception if the key does not exist.
get TValue get(TKey key, TValue def): Return the value for a key, or if it doesn't exist a default value.
has bool has(TKey key): Returns true if the key exists within the mapping.
keyUnion TKey[] keyUnion(TKey[] other): Return the set-union for an array of keys
keys auto keys(): Returns an array of keys from the mapping.
length size_t length(): Returns the length of the mapping.
opIndex TValue opIndex(TKey key): Indexing by key
opIndexAssign void opIndexAssign(TValue value, TKey key): Indexing assignment
pick TValue pick(bool delegate(TValue) f, TValue def = null): Returns a single value from the mapping, based on the return value of a delegate.
remove void remove(TKey key): Removes a key.
set TValue set(TKey key, TValue value): Set the key to a value.
subset auto subset(TKey[] keysWanted): Returns a new mapping from a subset of keys.
values auto values(): Returns an array of values from the mapping.
