Interface LookupCache<K,​V>

  • All Known Implementing Classes:

    public interface LookupCache<K,​V>
    An interface describing the required API for the Jackson-databind Type cache.

    Note that while interface itself does not specify synchronization requirements for implementations, specific use cases do. Typically implementations are expected to be thread-safe, that is, to handle synchronization.
