java.lang.Object

pro.verron.docxstamper.utils.ProcessorExceptionHandler

All Implemented Interfaces:

Thread.UncaughtExceptionHandler

public class ProcessorExceptionHandler
extends Object
implements Thread.UncaughtExceptionHandler

The ProcessorExceptionHandler class is responsible for capturing and handling uncaught exceptions that occur in a thread. It implements the Thread.UncaughtExceptionHandler interface and can be assigned to a thread using the setUncaughtExceptionHandler() method. When an exception occurs in the thread, the uncaughtException() method of ProcessorExceptionHandler will be called. This class provides the following features: 1. Capturing and storing the uncaught exception. 2. Executing a list of routines when an exception occurs. 3. Providing access to the captured exception, if any. Example usage: ProcessorExceptionHandler exceptionHandler = new ProcessorExceptionHandler(); thread.setUncaughtExceptionHandler(exceptionHandler);
