Syntax

public struct CachedServiceRef<TService> where TService : class

Type Parameters

Name	Description
TService	The type of the service to resolve and cache.

Remarks

Replaces the hand-rolled "private field + resolved flag + TryGetX method" triple that otherwise gets repeated at every call site that needs a single cached service reference. Composition-edge only. If the caller can take a constructor parameter, take one.

Methods

GetOrNull()

Returns the cached service, or null when it has not resolved yet.

Declaration

public TService GetOrNull()

Returns

Type	Description
TService

Invalidate()

Clears the cached resolution so the next call re-resolves through the locator.

Declaration

public void Invalidate()

TryGet(out TService)

Attempts to retrieve the cached service, resolving it through ServiceLocatorBridge the first time this succeeds.

Declaration

public bool TryGet(out TService service)

Parameters

Type	Name	Description
TService	service	The service instance if resolved; null otherwise.

Returns

Type	Description
bool	true if the service is cached or was just resolved; otherwise, false.
