As sven pointed out: "Keep in mind however that the second behavior can be changed by overriding TObject.NewInstance (the default implementation allocates the memory of the class and zeroes it)." |
|
|
"* The documentation should mention that, when a exception is raised inside a constructor, the destructor is automatically invoked;" This is afaik not correct if the exception is fatal. Like EOutOfMemory. It is also not correct if the exception is actually handled inside the constructor. |

"This is afaik not correct if the exception is fatal. Like EOutOfMemory. It is also not correct if the exception is actually handled inside the constructor." So, the documentation should mention that, if an exception is fatal or if an exception is handled inside a constructor, the destructor is not invoked, otherwise the destructor will be invoked. |

Added some comments about this in the 'class instantiation' section. |
