Tom Nolle explains how approaching mobile... User error handler must not modify error context. The checked exceptions that a method may raise are part of the method's signature. In runtime engine environments such as Java or .NET, there exist tools that attach to the runtime engine and every time that an exception of interest occurs, they record debugging information check over here

The CLU programming language had a feature with the interface closer to what Java has introduced later. Note, however, that there is no requirement that the parser continue to report additional errors after a call to fatalError. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples. Synchronous exceptions happen at a specific program statement whereas asynchronous exceptions can raise practically anywhere.[42][43] It follows that asynchronous exception handling can't be required by the compiler. this content

This function can be used for defining your own way of handling errors during runtime, for example in applications in which you need to do cleanup of data/files when a critical SAX parsers will use this method to report conditions that are not errors or fatal errors as defined by the XML recommendation. Filters may use this method to report other, non-XML errors as well.

This problem ended up being solved by RAII, but while RAII solves it, the fact that it is needed is still a source of criticism. The goal of well designed error handling code is to anticipate potential errors, and correct them at run time or to terminate code execution in a controlled, graceful method. If the error-handler function returns, script execution will continue with the next statement after the one that caused an error.
