  • Checks an ARTErrorInfo to see whether it falls into a given class of errors defined by the client library specification.

    In addition to putting shared error logic in a common place, it allows us to provide a mock instance when testing components that need to perform error checking, without having to worry about creating representative errors in our test cases.

  • ARTInternalLogCore is the type underlying ARTInternalLog, and defines the logging functionality available to components of the SDK.

    It’s responsible for receiving log messages from SDK components, performing additional processing on these messages, and forwarding the result to an object conforming to the ARTVersion2Log protocol.

    This protocol exists to give internal SDK components access to a rich and useful logging interface, whilst minimising the complexity (and hence the implementation burden for users of the SDK) of the ARTVersion2Log protocol. It also allows us to evolve the logging interface used internally without introducing breaking changes for users of the SDK.

    The initial interface of ARTInternalLogCore more or less mirrors that of the ARTLog class, for compatibility with existing internal SDK code. However, it will evolve as we gather requirements for the information logged by the SDK — see issues #1623 and #1624.

  • Consider an operation which can fail. If we attempt to perform the operation and it fails, we may wish to start performing a sequence of retries, until success or some other termination condition is achieved. An ARTRetryDelayCalculator describes the amount of time that we wish to wait before performing each retry in this sequence.

  • The ARTVersion2Log protocol represents a logger object that handles data emitted by the SDK’s logging system. It will be renamed ARTLog in the next major release of the SDK (replacing the existing class), at which point users of the SDK will need to provide an implementation of this protocol if they wish to replace the SDK’s default logger.

    The initial interface of ARTVersion2Log is based on that of the ARTLog class. However, its design will evolve as we gather further information about the following things:

    1. Requirements for the information logged by the SDK — see issues #1623 and #1624.

    2. Requirements for the data emitted by the SDK’s logging system — see issues #1618 and #1625.
