Constructor

Methods
resolve()
resolve<
T>(token,factory):Promise<T>
Defined in: packages/core/src/container/ScopedResolver.ts:27
Resolve a scoped binding, caching the instance for the rest of the request. Concurrent calls for the same token share a single in-flight promise.
Type Parameters
T
T
Parameters
token
unknown
factory
Factory<T>
Returns
Promise<T>
Throws
If the scope has already been flushed.
acquire()
acquire():
void
Defined in: packages/core/src/container/ScopedResolver.ts:60
Acquire a reference. Called synchronously by HttpContext.afterResponse() at registration time — before any await — so the request's finally block cannot flush the scope before the callback has a chance to run.
Returns
void
release()
release():
void
Defined in: packages/core/src/container/ScopedResolver.ts:74
Release a reference. When _refCount reaches 0, _doFlush() runs. Called by afterResponse() callback finally blocks and by flush().
Returns
void
flush()
flush():
void
Defined in: packages/core/src/container/ScopedResolver.ts:85
Called by Application.ts in the fetch handler's finally block. Releases the request's own reference (the initial 1). If afterResponse() callbacks are pending they hold their own references, so _doFlush() will not run until all of them have released.
Returns
void
