Hi,
I want to define a record that represents a tree items. The idea is each
item is a component that can have parent and children. The parent and the
children are components too,
So, I define this record by:
(defrecord Component [name children parent])
After, I declare 2 components:
(def parent (Component. "Parent" (atom {}) (atom nil)))
(def child (Component. "Child" (atom {}) (atom nil)))
To link the parent with the child, I do:
(swap! (:children parent) assoc :a child)
(reset! (:parent child) parent)
And bang, the second call raises an exception: StackOverflowError
java.util.regex.Pattern$BmpCharProperty.match (Pattern.java:3715)
If I reverse the code:
(reset! (:parent child) parent)
(swap! (:children parent) assoc :a child)
The reset! call passes fine but the swap! one fails with the same exception.
Where does this issue come from?
Thanks.
