| 79 | They translate the inplace C++ operators (+=, -=, ...) into the | |
| 80 | corresponding python equivalents(__iadd__,__isub__), etc, | |
| 81 | disabling the ownership of the input 'self' pointer, and assigning | |
| 82 | it to the returning object: | |
| 83 | ||
| 84 | %feature("self:disown") *::Operator; | |
| 85 | %feature("new") *::Operator; | |
| 86 | ||
| 87 | This makes the most common case safe, ie: | |
| 88 | ||
| 89 | A& A::operator+=(int i) { ...; return *this; } | |
| 90 | ^^^^ ^^^^^^ | |
| 91 | ||
| 92 | will work fine, even when the resulting python object shares the | |
| 93 | 'this' pointer with the input one. The input object is usually | |
| 94 | deleted after the operation, including the shared 'this' pointer, | |
| 95 | producing 'strange' seg faults, as reported by Lucriz | |
| 96 | (lucriz@sitilandia.it). | |
| 97 | ||
| 98 | If you have an interface that already takes care of that, ie, you | |
| 99 | already are using inplace operators and you are not getting | |
| 100 | seg. faults, with the new scheme you could end with 'free' elements | |
| 101 | that never get deleted (maybe, not sure, it depends). But if that is | |
| 102 | the case, you could recover the old behaviour using | |
| 103 | ||
| 104 | %feature("self:disown","") A::operator+=; | |
| 105 | %feature("new","") A::operator+=; | |
| 106 | ||
| 107 | which recovers the old behaviour for the class 'A', or if you are | |
| 108 | 100% sure your entire system works fine in the old way, use: | |
| 109 | ||
| 110 | %feature("self:disown","") *::operator+=; | |
| 111 | %feature("new","") *::operator+=; | |
