  2. 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.

  3. Exception handling - Wikipedia

    en.wikipedia.org/wiki/Exception_handling

    The default IEEE 754 exception handling behaviour of resumption following pre-substitution of a default value avoids the risks inherent in changing flow of program control on numerical exceptions. For example, the 1996 Cluster spacecraft launch ended in a catastrophic explosion due in part to the Ada exception handling policy of aborting ...

  4. Duff's device - Wikipedia

    en.wikipedia.org/wiki/Duff's_device

    The basic idea of loop unrolling is that the number of instructions executed in a loop can be reduced by reducing the number of loop tests, sometimes reducing the amount of time spent in the loop. For example, in the case of a loop with only a single instruction in the block code, the loop test will typically be performed for every iteration of ...

  5. Error hiding - Wikipedia

    en.wikipedia.org/wiki/Error_hiding

    In this C# example, all exceptions are caught regardless of type, and a new generic exception is thrown, keeping only the message of the original exception. The original stacktrace is lost, along with the type of the original exception, any exception for which the original exception was a wrapper, and any other information captured in the ...

  6. Exception safety - Wikipedia

    en.wikipedia.org/wiki/Exception_safety

    Exception safety is the state of code working correctly when exceptions are thrown. [1] To aid in ensuring exception safety, C++ standard library developers have devised a set of exception safety levels , contractual guarantees of the behavior of a data structure's operations with regards to exceptions.

  7. Exception handling syntax - Wikipedia

    en.wikipedia.org/wiki/Exception_handling_syntax

    C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions. In any case, a possible way to implement exception handling in standard C is to use setjmp/longjmp functions:

  8. Graceful exit - Wikipedia

    en.wikipedia.org/wiki/Graceful_exit

    In a language that supports formal exception handling, a graceful exit may be the final step in the handling of an exception. In other languages graceful exits can be implemented with additional statements at the locations of possible errors.

  9. List of Java keywords - Wikipedia

    en.wikipedia.org/wiki/List_of_Java_keywords

    The this keyword is also used to forward a call from one constructor in a class to another constructor in the same class. throw Causes the declared exception instance to be thrown. This causes execution to continue with the first enclosing exception handler declared by the catch keyword to handle an assignment compatible exception type. If no ...
