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 other abstractions when thrown by databinding.

        Note that it is possible that `null` may be returned if code throwing exception either has no access to 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.
