Question about primitives

Vitor Medina Cruz
Hello,

What is the correct behavior of a primitive when it fails? I should throw a specific Exception or do something else?

[]s,
Vitor

Re: Question about primitives

Call the method associated with the selector as if there is no primitive, right? But I want to know if I do that inside the primitive java method from ProtoObject or if that method should signal somehow (with an exception?) that the primitive failed leaving another part of the code to call the method associated with the selector. I could not figure that out looking at the ProtoObject primitive implementation and tests.

Re: Question about primitives

James Ladd
When a primitive fails the 'primitiveFailed' message should be sent to the receiver. I could be wrong about that selector and will have to look it up in Pharo. 

I have been away from the core of Redline for a while and I'm rather busy today - I will try and get back to you w more detail ASAP.
