* 1. We generate a unique ID for each Table instance using spl_object_hash()
|
|
* 2. We create a container binding with a key specific to this Table instance
|
|
* 3. The condition value (true/false) is stored in the container
|
|
*
|
|
* The container binding will be automatically cleaned up when the Table instance
|
|
* is garbage collected, as the binding key is unique to this instance.
