Class JacksonException

  • All Implemented Interfaces:
    Serializable
    Direct Known Subclasses:
    JsonProcessingException

    public abstract class JacksonException
extends IOException
    Base class for all Jackson-produced checked exceptions.

    For Jackson 2.x this base type is not widely used (instead, its main subtype JsonProcessingException is): it is provided more for forwards-compatibility purposes as 3.x will base all other types directly on it and deprecate JsonProcessingException (as well as chance its type to unchecked).

    Since:
    2.12

    • Method Detail

      • getLocation

        public abstract JsonLocation getLocation()
        Accessor for location information related to position within input or output (depending on operation), if available; if not available may return null.

        Accuracy of location information depends on backend (format) as well as (in some cases) operation being performed.

        Returns:
        Location in input or output that triggered the problem reported, if available; null otherwise.

      • getOriginalMessage

        public abstract String getOriginalMessage()
        Method that allows accessing the original "message" argument, without additional decorations (like location information) that overridden Throwable.getMessage() adds.
        Returns:
        Original, unmodified message argument used to construct this exception instance

      • getProcessor

        public abstract Object getProcessor()
        Method that allows accessing underlying processor that triggered this exception; typically either JsonParser or JsonGenerator for exceptions that originate from streaming API, but may be other types when thrown by databinding.

        Note that it is possible that null may be returned if code throwing exception either has no access to the processor; or has not been retrofitted to set it; this means that caller needs to take care to check for nulls. Subtypes override this method with co-variant return type, for more type-safe access.

        Returns:
        Originating processor, if available; null if not.
