Examples of org.apache.zookeeper.MultiTransactionRecord

org.apache.zookeeper.MultiTransactionRecord
Encodes a composite transaction. In the wire format, each transaction consists of a single MultiHeader followed by the appropriate request. Each of these MultiHeaders has a type which indicates the type of the following transaction or a negative number if no more transactions are included.
