  • Method Details

    • findMapping

      public <T extends Throwable> ExceptionMapper<T> findMapping(T exceptionInstance)
      Description copied from interface: ExceptionMappers
      Get an exception mapping provider for a particular exception instance.

      This method is similar to method ExceptionMappers.find(Class). In addition it takes into an account the result of the ExtendedExceptionMapper.isMappable(Throwable) of any mapper that implements Jersey ExtendedExceptionMapper API. If an extended exception mapper returns false from isMappable(Throwable), the mapper is disregarded from the search. Exception mapping providers are checked one by one until a first provider returns true from the isMappable(Throwable) method or until a first provider is found which best supports the exception type and does not implement ExtendedExceptionMapper API (i.e. it is a standard JAX-RS ExceptionMapper). The order in which the providers are checked is determined by the distance of the declared exception mapper type and the actual exception type.

      Note that if an exception mapping provider does not implement ExtendedExceptionMapper it is always considered applicable for a given exception instance.

      Specified by:
      findMapping in interface ExceptionMappers
      Type Parameters:
      T - type of the exception handled by the exception mapping provider.
      Parameters:
      exceptionInstance - exception to be handled by the exception mapping provider.
      Returns:
      an ExceptionMapper for the supplied exception instance type or null if none is found.

    • find

      public <T extends Throwable> ExceptionMapper<T> find(Class<T> type)
      Description copied from interface: ExceptionMappers
      Get an exception mapping provider for a particular class of exception. Returns the provider whose generic type is the nearest superclass of type.
      Specified by:
      find in interface ExceptionMappers
      Type Parameters:
      T - type of the exception handled by the exception mapping provider.
      Parameters:
      type - the class of exception.
      Returns:
      an ExceptionMapper for the supplied type or null if none is found.
