Interface Resource

  • All Known Subinterfaces:

    @ConsumerType
    public interface Resource
    A resource is the representation of a uniquely identified and typed data. A resource declares requirements that need to be satisfied by capabilities before it can provide its capabilities.

    Instances of this type must be effectively immutable. That is, for a given instance of this interface, the methods defined by this interface must always return the same result.
