beginTransaction

Starts a transaction on the geodatabase. This method starts a new transaction on the geodatabase. The transaction fails to begin if another transaction is already active. A geodatabase cannot be synchronized while a transaction is active.

Transactions can be started and stopped on any thread. Any edits that take place after a call to Geodatabase.beginTransaction() but before a call to either Geodatabase.commitTransaction() or Geodatabase.rollbackTransaction() will be considered part of that transaction, no matter what thread made the edit.
