T
- the result type of the runnablepublic interface RunnableWithResult<T>
Extends the core Java Runnable
interface with the ability to return
a result. Useful for returning results of read operations from the
TransactionalEditingDomain.runExclusive(Runnable)
method.
Also, because read transactions can roll back on commit if, for example, some other thread performs a concurrent write that corrupts the data being read, this interface also provides a means to set a status to indicate success or failure of the transaction.
