webpack.WeakTupleMap

Stores values by tuple keys while using WeakMap for object elements so the cache can release entries when those objects are collected.

new WeakTupleMap(): WeakTupleMap<K, V>

cachedProvide(compute, thisArg, args): V

Memoizes compute(thisArg, ...args) under the tuple key [compute, ...args], computing it on a miss. Equivalent to provide(compute, ...args, () => compute(thisArg, ...args)) but without allocating that closure (or an extra rest array) on every call — ModuleGraph#cached runs this on hot paths where most calls hit the cache and the closure would be pure waste.

clear(): void

Clears the stored value and all strong and weak child maps from this node.

delete(...args?): void

Removes the value stored for the tuple key without pruning the trie.

get(...args?): V | undefined

Returns the value stored for the exact tuple key, if any.

has(...args?): boolean

Checks whether the exact tuple key has a stored value.

provide(...args?): V

Returns an existing value for the tuple or computes, stores, and returns a new one when the tuple is missing.

set(...args?): void

Stores a value at the node identified by the provided tuple key.
