Class ClassMapErrorHandler

All Implemented Interfaces:

public class ClassMapErrorHandler
extends Object
implements ErrorHandler
Error handler that allows the registration of one or more error handler for subclasses to Throwable.

Use the addErrorHandler(Class, ErrorHandler) to register error handlers for specific exceptions. When the handleError(Throwable) is invoked it checks the class of the throwable and looks for error handlers for that class. If it can't find an error handler it will check the superclass and so on. If no error handler is found the orginal error is re-thrown.

      public boolean handleError​(Throwable t) throws Throwable
      Description copied from interface: ErrorHandler
      Handle an error. If it is decided that the error is a final error this method should rethrow the same or a different exception. If if is decided that it is possible to continue with the current operation true should be returned. If false is returned it indicates that this error handled doesn't know how to handle the error. The caller should try another error handler or throw an exception.
      Specified by:
      handleError in interface ErrorHandler
      t - The error to handle
      TRUE if the error was handled successfully and the execution should continue with the next item
      Throwable - If the error is final and can't be solved
