And here is the sum up version, implemented by a mixin which could be
added somewhere in the class hierarchy, or may even be applied to an
existing class hierarchy by using qx.Class.patch:
qx.Mixin.define("MCallGetter",
{
members :
{
callGetter : function(propertyName) {
var methodName = 'get'+qx.lang.String.firstUp(propertyName);
if(qx.lang.Type.isFunction(object[methodName])) {
value = object[methodName].call(object);
return value;
}
else {
return null;
}
}
});
All object instances of classes having the mixin may now simply execute:
var value = object.callGetter('dewpoint');
