Context.getOrUndefined

Returns the service currently stored for a key, or undefined when the key is absent.

When to use

Use when you need to read the service stored for a key without resolving Context.Reference defaults.

Gotchas

This is a raw lookup and does not resolve default values for Context.Reference keys.

See

• getOption for a reference-aware optional lookup

Signature

declare const getOrUndefined: { <S, I>(key: Key<I, S>): <Services>(self: Context<Services>) => S | undefined; <Services, S, I>(self: Context<Services>, key: Key<I, S>): S | undefined; }
