StreamSpecification

public StreamSpecification(boolean enableStream)

参数:

enableStream - Must be false, indicating that Stream is disabled.

StreamSpecification

public StreamSpecification(boolean enableStream,
                           int expirationTime)

Construct a StreamSpecification object. Note: The enableStream parameter must be true because when enableStream is false, expirationTime cannot be specified. If you need to set the Stream to be off, please use the other constructor.
