FIRMemoryLRUGCSettings


@interface FIRMemoryLRUGCSettings
    : NSObject <NSCopying, FIRMemoryGarbageCollectorSettings>

Configures the SDK to use a least-recently-used garbage collector for memory cache.

Once configured, the SDK will attempt to remove documents that are least recently used in batches, if the current cache size is larger than the given target cache size. Default cache size is 100MB.

To use, create an instance using one of the initializers, then initialize MemoryCacheSettings with this instance.

  • Creates an instance of FIRMemoryLRUGCSettings, with default target cache size 100MB. The SDK will run garbage collection if the current cache size is larger than 100MB.

    Declaration
