  2. Exception handling - Wikipedia

    en.wikipedia.org/wiki/Exception_handling

    An exception handling mechanism allows the procedure to raise an exception [2] if this precondition is violated, [1] for example if the procedure has been called on an abnormal set of arguments. The exception handling mechanism then handles the exception. [3] The precondition, and the definition of exception, is subjective.

  3. Exception handling (programming) - Wikipedia

    en.wikipedia.org/wiki/Exception_handling...

    The implementation of exception handling in programming languages typically involves a fair amount of support from both a code generator and the runtime system accompanying a compiler. (It was the addition of exception handling to C++ that ended the useful lifetime of the original C++ compiler, Cfront. [18]) Two schemes are most common.

  4. Exception handling syntax - Wikipedia

    en.wikipedia.org/wiki/Exception_handling_syntax

    The Perl mechanism for exception handling uses die to throw an exception when wrapped inside an eval {...}; block. After the eval, the special variable $@ contains the value passed from die. Perl 5.005 added the ability to throw objects as well as strings. This allows better introspection and handling of types of exceptions.

  5. Exception safety - Wikipedia

    en.wikipedia.org/wiki/Exception_safety

    A key mechanism for exception safety is a finally clause, or similar exception handling syntax, which ensure that certain code is always run when a block is exited, including by exceptions. Several languages have constructs that simplify this, notably using the dispose pattern , named as using , with , or try -with-resources.

  6. Exception chaining - Wikipedia

    en.wikipedia.org/wiki/Exception_chaining

    Exception chaining, or exception wrapping, is an object-oriented programming technique of handling exceptions by re-throwing a caught exception after wrapping it inside a new exception. The original exception is saved as a property (such as cause) of the new exception. The idea is that a method should throw exceptions defined at the same ...

  7. Microsoft-specific exception handling mechanisms - Wikipedia

    en.wikipedia.org/wiki/Microsoft-specific...

    Microsoft Structured Exception Handling is the native exception handling mechanism for Windows and a forerunner technology to Vectored Exception Handling (VEH). [1] It features the finally mechanism not present in standard C++ exceptions (but present in most imperative languages introduced later).

  8. Automated exception handling - Wikipedia

    en.wikipedia.org/wiki/Automated_Exception_Handling

    This mechanism enables the automated handling of software errors independent of the application source code and of its developers. It is a direct artifact of the runtime engine paradigm and it enables unique advantages to the software life cycle that were unavailable before.

  9. Switch statement - Wikipedia

    en.wikipedia.org/wiki/Switch_statement

    A number of languages implement a form of switch statement in exception handling, where if an exception is raised in a block, a separate branch is chosen, depending on the exception. In some cases a default branch, if no exception is raised, is also present. An early example is Modula-3, which use the TRY...
