Interface TxnIntCallable

public interface TxnIntCallable
A transactional callable contains the logic that needs to be executed transactionally and normally is executed by theTxnExecutor
. This transactional callable is optimized for retuning a primitive type: int. Using this TxnIntCallable instead of theTxnCallable
is that no object wrapper needs to be created and there is no reason to deal with a potential null value.- Author:
