Class StoreCache

Namespace

McServerLauncher.Services

Assembly

McServerLauncher.dll

Two-level cache (memory, then disk, then the network) for the store's API responses. It exists so that opening a mod — and going back and opening it again — costs one request, not one per visit, and so that a project already seen still opens with no connection.

Concurrent callers asking for the same key share a single fetch: opening a details page kicks off the project, its versions and its dependencies at once, and the related-mods strip may ask for a project that is already in flight.

Entries are kept on disk beyond their freshness window on purpose: when the network fails, a stale entry is a much better answer than an empty page. Anything older than McServerLauncher.Services.StoreCache.MaxDiskAge is pruned once per run.

Shared

Shared instance: the cache is only useful if every view model hits the same one.

StoreCache

Methods

GetOrFetchAsync<T>(string, TimeSpan, Func<CancellationToken, Task<T?>>, CancellationToken)

Returns the cached value when it is younger than ttl, otherwise calls fetch and stores the result. A failed or empty fetch falls back to a stale copy when there is one, so the UI degrades to "slightly old" instead of "nothing".

public Task<T?> GetOrFetchAsync<T>(string key, TimeSpan ttl, Func<CancellationToken, Task<T?>> fetch, CancellationToken ct = default) where T : class

Parameters

key string

ttl TimeSpan

fetch Func<CancellationToken, Task<T>>

ct CancellationToken

Returns

Task<T>

Type Parameters

T

Invalidate(string)

Drops a key from memory so the next read goes back to the network.

public void Invalidate(string key)

Parameters

key string
