delivered(num: Long): Long
Indicate that the specified number of elements has been delivered.
Indicate that the specified number of elements has been delivered. Returns the remaining demand. This is an atomic operation. It must only be called from the synchronous action context which performs the streaming.

def
demandBatch: Long
Get the current demand that has not yet been marked as delivered and mark it as being in the current batch.
Get the current demand that has not yet been marked as delivered and mark it as being in the current batch. When this value is negative, the initial streaming action is still running and the real demand can be computed by subtracting
Long.MinValue
from the returned value. -
def
emit(v: Any): Unit
Emit a single result of the stream.
Emit a single result of the stream. Any Exception thrown by this method should be passed on to the caller.

pin: Unit
Pin the current session.
Pin the current session. Multiple calls to
pin
may be nested. The same number of calls tounpin
is required in order to mark the session as not pinned anymore. A pinned session will not be released at the end of a primitive database action. Instead, the same pinned session is passed to all subsequent actions until it is unpinned. Note that pinning does not force an actual database connection to be opened. This still happens on demand. May only be called from a synchronous action context.- Definition Classes
