Class FunctionTagging

  • public final class FunctionTagging
extends java.lang.Object
    Wraps the regular io.reactivex.functions function types and appends the user-specified tag to the exception the wrapped function produces.

    The tagging can be optionally enabled before assembling flows, thus the overhead can be limited to when diagnosing problems around failing functions.

    Each functional type has its own {code tagX} postfix to avoid lambda ambiguity.

    Since:
    0.17.4

      • enable

        public static void enable()
        Enable the function tagging wrappers in the tagX methods.

      • disable

        public static void disable()
        Disable the function tagging wrappers in the tagX methods.

        Note that disabling doesn't remove the wrappers from previously tagged functions.

      • isEnabled

        public static boolean isEnabled()
        Returns true if the function tagging wrappers are enabled.
        Returns:
        true if the function tagging wrappers are enabled
