Map

HashMap class template to store the raw data of values of a certain size. Manages a mapping from K to ubyteV, leaving the hash function implementation to the subclass (abstract BucketSet.toHash()). Since static arrays cannot be returned, the access methods return a void[] slice to the value.

class Map(V, K)
class Map(size_t V, K)
abstract
class Map : BucketSet!(V, K)(
size_t V
K
) {
import ocean.core.Verify;;
alias MapIterator = .MapIterator!(Bucket.Element.Val, K);
mixin IteratorClass!(BucketSet!(V, K).Iterator, MapIterator) ;
this(size_t n, float load_factor);
void[] opBinaryRight(K key);
void[] get(K key);
alias opIndex = get;
void[] put(K key, bool added);
void[] put(K key);
void[] opIndexAssign(void[] val, K key);
void[] remove(K key);
int opApply(MapIterator.Dg dg);
int opApply(MapIterator.Dgi dgi);
typeof(this) clear(void[] val_init);
}

Constructors

this this(size_t n, float load_factor): Constructor.

MapIterator alias MapIterator = .MapIterator!(Bucket.Element.Val, K): MapIterator template instance.
opIndex alias opIndex = get: Obtains a the value mapped by key. A value for key is expected to exist in the map.

Functions

clear typeof(this) clear(void[] val_init): Removes all elements from all buckets and sets the element values to val_init.
get void[] get(K key): Obtains a reference to the value mapped by key. A value for key is expected to exist in the map.
opApply int opApply(MapIterator.Dg dg): 'foreach' iteration over key/value pairs currently in the map.
opApply int opApply(MapIterator.Dgi dgi): Same method as above, but includes a counter
opBinaryRight void[] opBinaryRight(K key): In operator. Looks up the value mapped by key.
opIndexAssign void[] opIndexAssign(void[] val, K key): Adds or updates a mapping from key to val, copying the content of val into the map.
put void[] put(K key, bool added): Looks up the mapping for key or adds one if not found.
put void[] put(K key): Adds or updates a mapping from the specified key. Note that, if a new mapping was added (added outputs true), the returned slice may reference a previously removed value. If this is not desired, copy the desired initial value into the sliced buffer returned by remove().
remove void[] remove(K key): Removes the mapping for the specified key.

Mixins

__anonymous mixin IteratorClass!(BucketSet!(V, K).Iterator, MapIterator): Mixin of the specialized iterator classes which inherit from BucketSet.Iterator.
