| | Exception handling - Wikipedia, the free encyclopedia |
 | | Exception handling is a programming language construct or computer hardware mechanism designed to handle runtime errors or other problems (exceptions) which occur during the execution of a computer program. | | | Exception handling can be used to pass information about error situations that occur within library code to its users, and selectively respond to those errors. | | | In those languages, the advent of an exception (more precisely, an exception handled by the language) unwinds the stack of function calls until an exception handler is found. |

| | Error and Exception Handling in C# and .NET |
| | Exception handling is an in built mechanism in.NET framework to detect and handle run time errors. | | | An object of an exception is that describe the exceptional conditions occur in a code That means, we are catching an exception, creating an object of it, and then throwing it. | | | Structured exception handling is a fundamental part of the CLR and provides.Net programmers a great way of managing errors. |

| | perl.com: Object Oriented Exception Handling in Perl |
| | Exceptions come to the rescue by allowing contextual information to be captured at the point where the error occurs and propagate it to a point where it can be effectively used/handled. | | | An exception handler is a piece of code used to gracefully deal with the exception. | | | If the exception object implements stringification, by overloading the string operations, then the stringified version of the object would be available whenever $@ is used in string context. |

| | ANSI Standard Exception Handling |
| | When the exception framework is activated by a signaler, it searches for the handler by analyzing the program execution history. | | | Several incompatible exception handling frameworks were introduced by various Smalltalk implementations before the introduction of the ANSI Standard. | | | With a typical exception handling framework, a program somehow defines a set of exceptional situations that can occur while it runs and associates blocks of code with particular kinds of error. |

| | Scheme Exception Handling |
| | An exception is raised by the system whenever an error is to be signaled or whenever the system determines that evaluation cannot proceed in a manner consistent with the semantics of Scheme. | | | The denotation of system exceptions and the initial current exception handler are system-dependent, as is the behavior whenever a handler for an exception raised by the system returns to its continuation. | | | When the new current exception handler is invoked with exn, the predicates are invoked, in sequence, with exn until a true value is returned. |

| | The Essence of OOP using Java, Exception Handling |
| | To be useful, the exception object should probably contain information about the exception, including its type and the state of the program when the exception occurred. | | | Checked exceptions are all exception objects instantiated from subclasses of the Exception class other than those of the RuntimeException class. | | | Although the version with exception handling contains about seventeen lines of code, it is orderly and easy to understand. |

| | Error and Exception Handling |
| | On the other hand, it would probably be inappropriate to throw and handle exceptions in the inner loop of this computation because that could have a significant performance impact. | | | For example, if your exception reports a numeric range error, it's important to have the actual numbers involved available as numbers in the exception class' public interface where error reporting code can do something intelligent with them. | | | There are various ways to avoid copying string objects when exceptions are copied, including embedding a fixed-length buffer in the exception object, or managing strings via reference-counting. |

| | Best practices in EJB exception handling |
| | Because session EJB components and entity EJB components handle system exceptions similarly, we'll focus on entity EJB components for the examples throughout this section, but keep in mind that most of the examples can also be applied to working with session EJB components. | | | In the absence of a strategy for exception handling, different developers on the project team will likely write code to handle exceptions differently. | | | A system exception is defined as either a checked exception or an unchecked exception, from which an EJB method cannot recover. |

| | Exception Handling in REALbasic |
| | Exception (or error) handling is hardly documented in RB; the docs only give you some short explanation of its syntax, but no real-world examples or other ideas for what it is good for. | | | It would be nicer if the subroutine can raise its exceptions with some more information, like a text message explaining the error condition in more detail or even giving more information about the parameters that are bound to the condition (like the file name or the value of the non-positive number). | | | If you raise an Exception in your code, it works like this: First, it acts as if you had used the RETURN statement instead: The procedure will be exited. |

| | Exception-Handling Statements |
| | The exception handler can attempt to recover from the error or, if it determines that the error is unrecoverable, provide a gentle exit from the program. | | | This is a brief overview of the statements used in reporting and handling errors. | | | It means that the normal flow of the program is interrupted and that the runtime environment attempts to find an exception handler—a block of code that can handle a particular type of error. |

| | Exception-Safety in Generic Components |
| | For example, the designer of a generic component might require that an operation which is used in the component's destructor not throw any exceptions. | | | That alone gives programs using exceptions performance equivalent to that of a program which ignores the possibility of errors. | | | ``Exceptions make it more difficult to reason about a program's behavior.'' Usually cited in support of this myth is the way ``hidden'' execution paths are followed during stack-unwinding. |

| | Exception Handling for Fun and Profit |
| | Eating exceptions means that the information about the error – which could make fixing it easy – is gone for good. | | | Added into the Delphi language back at the very beginning, exception handling was a fundamental change to the way we thought about and wrote our code. | | | This code is better than simply eating all exceptions, no matter what you do with the exception, because at the very least, it will only trap that one exception and not any exception that comes along. |
