Accessors

dimension

get dimension(): number
Number of distinct keys.

Returns number
- Defined in pkg/util/src/key-map.ts:61

size

get size(): number
Number of values.

Returns number
- Defined in pkg/util/src/key-map.ts:64

Methods

[iterator]

[iterator](): IterableIterator<[key: K, value: V]>
Iterate over key-value pairs.

Returns IterableIterator<[key: K, value: V]>
Implementation of Iterable.[iterator]
- Defined in pkg/util/src/key-map.ts:120

add

add(key, value): number
Add a key-value pair. Values are stored in a Set, so duplicates are skipped.
Parameters
- key: K
- value: V
Returns number
count(key) after the operation.
- Defined in pkg/util/src/key-map.ts:81

associations

associations(): IterableIterator<[key: K, values: ReadonlySet<V>]>
Iterate over key and associated values.

Returns IterableIterator<[key: K, values: ReadonlySet<V>]>
- Defined in pkg/util/src/key-map.ts:115

count

count(key): number
Count values associated with a key.
Parameters
- key: K | L
Returns number
- Defined in pkg/util/src/key-map.ts:67

list

list(key): ReadonlySet<V>
List values associated with a key.
Parameters
- key: K | L
Returns ReadonlySet<V>
- Defined in pkg/util/src/key-map.ts:72

remove

remove(key, value): number
Remove a key-value pair. No-op if key-value does not exist.
Parameters
- key: K | L
- value: V
Returns number
count(key) after the operation.
- Defined in pkg/util/src/key-map.ts:99
