    Interface Logger

    Represents Ice's abstraction for logging and tracing. Applications can provide their own logger by implementing this abstraction and supplying a logger in InitializationData.

    The Ice runtime calls print, trace, warning and error while performing internal operations. Implementations of these methods must not throw exceptions: a thrown exception can leave the Ice runtime in an inconsistent state or terminate the program.

    InitializationData

    interface Logger {
        cloneWithPrefix(prefix: string): Logger;
        error(message: string): void;
        print(message: string): void;
        trace(category: string, message: string): void;
        warning(message: string): void;
    }
    Index

      Parameters

      • message: string

        The error message to log.

      Returns void

      An implementation of this method must not throw exceptions.
