If I define a static variable like this (especially for Arrays),
statics :
{
TABLE_COLUMN_ARRAY : ["C1","C2","C3"]
}
This TABLE_COLUMN_ARRAY is passed to qx.ui.table.model.Remote.setColumns().
Is there a possibility for memory leak clearing the above array? I don't
know how Qooxdoo cleans the internal object (probably it could be behaviour
of browser). I have been using lot of CONSTANT variables as properties, for
which I could ideally use static constants.
For some languages like Java/C++, when an array is declared as public static
variable, the Garbage Collection may struggle to clear the Object from
memory because of static references outside.
Thanks.
