Returns a string representation of the transactional value in this instance for debugging convenience.
Returns a string representation of the transactional value in this
instance for debugging convenience. The
Ref reads (and writes)
performed while constructing the result will be discarded before
returning. This method works fine outside a transaction.
If this method is called from within a transaction that is already
Txn.Rolledback), a string describing the reason
for the outer transaction's rollback will be returned.
Returns some value that is suitable for examination in a debugger,
or returns a
Txn.RollbackCause if called from inside a doomed atomic
This trait implements methods that can be used to examine the content of transactional data structures in a debugger with minimal modification to the behavior of the program. Normal transactional reads would add to an atomic block's read set, which could reduce the number of valid program execution orders.
dbgValueperform transactional reads, but then erase them from the enclosing transaction (if any).
You can use these methods from an IDE debugger manually, by watching
If you use Eclipse, you can make this method the default view by going to Window->Preferences->Java[+]->Debug[+]->Detail Formatters and entering the code snippet

If you use IntelliJ IDEA, go to File->Settings...->Debugger->Data Type Renderers and create a new renderer for
