unique_key method for nodes

  1. garfieldnate avatargarfieldnate

I added a method called unique_key which returns a key guaranteed to be unique and unchanging for a given node. I find this useful in creating hash structures with the unique_key return value as the key.

The actual method is very simple. The XS code turns the node pointer into an integer and then returns it. I believe that this is correct because of the implementation of isSameNode.

I also included tests, documentation, Changes, and Manifest updates.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
