The ``throw`` keyword can also be used as an alternative to ``revert()``. +.. note:: + From version 0.4.13 the ``throw`` keyword is deprecated and will be phased out in the future. + When exceptions happen in a sub-call, they "bubble up" (i.e. exceptions are rethrown) automatically. Exceptions to this rule are ``send`` and the low-level functions ``call``, ``delegatecall`` and ``callcode`` -- those return ``false`` in case of an exception instead of "bubbling up". |
