Hi
currently the rdBuff is shared between all instatces
try to create the instance variable (here rdBuff) inside the initialize
function
and with the this keyword its not default like in C++ etc...
var SomeClass = Class.create({
initialize: function(name) {
this.rbBuffer = {};
},
setBuffer: function(val) {
this.rbBuffer.test = val;
},
.
.
.
hope it helped
cheers

Hi,
I've got a weird behavior here, or rather a behavior I don't
understand. If you take the following Class:
---
var SomeClass = Class.create({
rbBuffer: nulll,
setBuffer: function(val) {
this.rbBuffer = val;
},
getBuffer: function() {
return this.rbBuffer;
}
});
---
and play around a little bit:
---
var c1 = new SomeClass();
var c2 = new SomeClass();
c1.setBuffer(true);
c2.setBuffer(false);
log(c1.getBuffer()); // PRINTS TRUE
log(c2.getBuffer()); // PRINTS FALSE
---
everything works as expected. But if you alter that class and make
rbBuffer a JSON-object and try to set/get properties of that object,
it kinda gets shared:
---
var SomeClass = Class.create({
rbBuffer: {},
setBuffer: function(val) {
this.rbBuffer.test = val;
},
getBuffer: function() {
return this.rbBuffer.test;
}
});
var c1 = new SomeClass();
var c2 = new SomeClass();
c1.setBuffer(true);
c2.setBuffer(false);
log(c1.getBuffer()); // PRINTS FALSE
log(c2.getBuffer()); // PRINTS FALSE
---
rbBuffer.test of the first object is overwritten with the value you
set on the second object, as if the use the same variable.
Does anyone know why this is, and how to work with it?
Thanks
Lukas
