pyflink.datastream.state.ReadOnlyBroadcastState

class ReadOnlyBroadcastState

A read-only view of the BroadcastState. Although read-only, the user code should not modify the value returned by the get() or the items returned by items(), as this can lead to inconsistent states. The reason for this is that we do not create extra copies of the elements for performance reasons.

contains(key)	Returns whether there exists the given mapping.
