SessionPool

@webda/mock

Class: SessionPool

Defined in: engine/pool.ts:10

Session-scoped instance pool. Holds every instance generated during one generate() / generateGraph() call so that later relation-aware fields (@ModelLink, @ModelRelated) can reference real earlier instances rather than made-up ids.

All randomness is driven by the constructor-injected rng: () => number so outcomes are reproducible when the caller supplies a seeded RNG.

Constructors​

Constructor​

new SessionPool(rng?): SessionPool

Defined in: engine/pool.ts:17

Parameters​

rng?​

() => number

deterministic RNG returning a float in [0, 1). Defaults to Math.random when no seed is needed.

Returns​

SessionPool

Methods​

add()​

add(instance): void

Defined in: engine/pool.ts:24

Add an instance to the pool, keyed by its constructor.

Parameters​

instance​

unknown

the object to add. Non-objects are ignored.

Returns​

void

pickMany()​

pickMany<T>(ctor, count): T[]

Defined in: engine/pool.ts:55

Pick a unique subset of instances of the given class.

Type Parameters​

T​

T

Parameters​

ctor​

(...args) => T

the class to pick from.

count​

number

requested subset size; clamped to pool.size(ctor).

Returns​

T[]

the selected instances (may be shorter than count).

pickOne()​

pickOne<T>(ctor): T

Defined in: engine/pool.ts:41

Pick one random instance of the given class from the pool.

Type Parameters​

T​

T

Parameters​

ctor​

(...args) => T

Returns​

T

a pooled instance, or null when the pool has none.

size()​

size(ctor): number

Defined in: engine/pool.ts:77

Number of pooled instances of the given class.

Parameters​

ctor​

(...args) => unknown

the class to count.

Returns​

number

the current pool size for that class (0 when absent).
