## StreamSubjectsMode Enum

Which subjects a stream covers by default \- the per\-stream fixation of the transmitter's
"default\_subjects" advertisement \(SSF 1\.0 Section 7\.1\), taken at stream creation so a later
change of the advertisement does not silently re\-scope existing streams\.

```csharp
public enum StreamSubjectsMode
```
### Fields

###### `All` 0 {#Abblix.SharedSignals.Transmitter.StreamSubjectsMode.All}

Every subject appropriate for the stream is on it until removed: the receiver's removals
carve subjects out, and its additions bring carved\-out subjects back
\(SSF 1\.0 Section 7\.1, "ALL"\)\.

###### `None` 1 {#Abblix.SharedSignals.Transmitter.StreamSubjectsMode.None}

No subject is on the stream until the receiver adds it \(SSF 1\.0 Section 7\.1, "NONE"\)\.
