However, the old Signal hierarchy will remain in existance, since it allows |
52 |
funny instance-specific and anonymous exception handling schemes to be |
|
53 |
implemented, which are hard to built using class-based exceptions. |

Signal and Exception provide a framework for exception handling. |
44 | 56 |
|
70 | 57 |
A Signal object is usually defined somewhere up in the calling chain |
58 |
and associated with some abnormal event. Many signals are also |
|
59 |
created at startup time and reused. |
|
44 | 60 |
|
70 | 61 |
When the event is raised (by Signal>>raise) the control will be either |
62 |
given to a debugger or - if a handler was defined - to the handler. |
|
63 |
The handler will get a description of what (and where) happened in an |
|
120 | 64 |
Exception object and can decide how to react on the situation (i.e. |
65 |
proceed, return or restart). |
|
70 | 66 |
|
67 |
There is also a companion class called SignalSet, which allows handling |
|
68 |
multiple signals with one handler (for example all arithmetic signals). |
|
69 |
And, finally there is a very special SignalSet which allows catching |
|
70 |
any signal (SignalSet>>anySignal). |
|
71 |
||
171 | 72 |
Since there is no official documentation on signal handling (i.e. none |
73 |
of the books describes it), this Signal implementation has been modeled |
|
74 |
after what some PD programs seem to expect and what alpha/beta testers told |
|
75 |
me it should look like. |
|
76 |
It may not be perfect and undergo minor changes. |
|
44 | 77 |
|
120 | 78 |
special: |
79 |
||
70 | 80 |
In addition to the nested catch & throw mechanism, signals can also be |
120 | 81 |
used when no such handler scope exists. To support this, signals can be |
82 |
assigned a handlerBlock, which gets evaluated with the exception as argument |
|
83 |
in case no handler was found (on the stack). |
|
70 | 84 |
|
171 | 85 |
If no handler was found (i.e. neither a handler context on the stack, nor |
86 |
a static handler block), the NoHandlerSignal will be raised instead, |
|
120 | 87 |
passing it the original exception in its exception-parameter. |
171 | 88 |
This NoHandlerSignal can be handled just like any other signal. |
89 |
(therefore, it is possible to catch any error by catching NoHandlerSignal. |
|
70 | 90 |
|
120 | 91 |
When the NoHandler signal is raised, and neither a handler-context, nor |
92 |
a handler block is defined for it, an emergencyHandler(-block) is evaluated. |
|
93 |
This block is either provided by the current process |
|
94 |
(see Process>>emergencySignalHandler) or as a global default by the Exception |
|
95 |
class (see Exception>>emergencyHandler). |
|
96 |
The default emergencyHandlerBlock (from Exception) will bring up a debugger. |
|
97 |
||
98 |
HandlerBlocks allow a global (if its the EmergencyHandler in Exception) |
|
99 |
or per-process signal handling to be added. Even to code which was never |
|
100 |
planned to handle signals. |
|
70 | 101 |
|
171 | 102 |
See samples in 'doc/coding' and actual raise code in Exception. |
