Class GCRules (2.51.2)

public final class GCRules

Wraps GcRule protocol buffer object and exposes a friendly API.

Note: Garbage collection executes opportunistically in the background, and so it's possible for reads to return a cell even if it matches the active GC expression for its family. Please use appropriate filters in your reads to exclude cells which are eligible for garbage collection.
