||
3 | * One important design goal was the principle of the least surprise. |
||
4 | * As PHP is a fully dynamic language with nearly no type-safety, it is common to shoot yourself into the foot because of accidentally mixing up incompatible types. |
||
5 | * We protect you from these programing errors by asserting that every callback functions you supply to the library must return a correctly typed value. |
||
6 | * In addition, every supported aggregate function will throw an exception if you are accidentally mixing up incompatible types. |
||
7 | * |
||
8 | * This means that we made this library totally predictable in what it does, and verified that every function has its defined exceptions |
||
9 | * which are thrown when certain operations fail, or if certain types are not correct. |
||
10 | * |
