Note: |
19717 | 52 |
The instance based Signal framework is being replaced by |
53 |
class based exceptions. |
|
54 |
I.e. what used to be instances of Signal/QuerySignal is being |
|
55 |
rewritten into subclasses of Exception/Error/Query and Warning. |
|
56 |
Although the functionality is basically unchanged, the new |
|
20089 | 57 |
class based exceptions are easier to instantiate (no need for |
19717 | 58 |
creation in a classes initialize method), easier to use (no real |
20095 | 59 |
need for Signal-constant accessors) and allow for easier parameter |
19717 | 60 |
passing (not only a single parameter, but allows for individual |
61 |
exception subclasses to add additional state). |

Raising: |
19717 | 120 |
two different raising messages are to be used, |
121 |
depending on whether the exception is proceedable or not |
|
122 |
||
123 |
For some stupid reason, someone decided that the raise-code checks if |
|
124 |
the raising messages matches to what the signal thinks is its proceedability. |
|
125 |
(i.e. not only do both the sender and the signal itself specify proceedability, |
|
126 |
this is checked by the raise code and a warning is generated if there is a mismatch) |
|
127 |
This used to be even worse (WrongProceedabilityError), but we relaxed this to |
|
128 |
a message sent to stderr. |
|
129 |
||
130 |
That means, that PROCEEDABLE signals must be raised with: |
|
131 |
raiseRequest |
|
132 |
and NON-PROCEEDABLE signals must be raised with: |
|
133 |
raise |
|
134 |
||
20800 | 135 |
If you don't know/care as a raiser, you can use |
19717 | 136 |
raiseSignal |
137 |
which checks for proceedability and sends the appropriate message. |
|
