Examples of org.jgroups.util.StateTransferResult

org.jgroups.util.StateTransferResult
Encapsulates the result of a state transfer. When buffer is set, then this is the result of a state transfer with STATE_TRANSFER. When exception is non-null, then an exception occurred. When both fields are null, then the (streaming) state transfer was successful. @author Bela Ban @since 3.0
