## Orleans

- [ImplicitChannelSubscriptionAttribute](/orleans/docs/api/csharp/microsoft.orleans.broadcastchannel/orleans.implicitchannelsubscriptionattribute/) - The [Orleans.ImplicitStreamSubscription] attribute is used to mark grains as implicit stream subscriptions.
- [RegexImplicitChannelSubscriptionAttribute](/orleans/docs/api/csharp/microsoft.orleans.broadcastchannel/orleans.regeximplicitchannelsubscriptionattribute/) - The [Orleans.RegexImplicitStreamSubscription] attribute is used to mark grains as implicit stream subscriptions by filtering stream namespaces to subscribe using a regular expression.

- [IChannelIdMapper](/orleans/docs/api/csharp/microsoft.orleans.broadcastchannel/orleans.broadcastchannel.ichannelidmapper/) - Common interface for component that map a [ChannelId](/orleans/docs/api/csharp/microsoft.orleans.broadcastchannel/orleans.broadcastchannel.channelid/) to a [GrainId](/orleans/docs/api/csharp/microsoft.orleans.core.abstractions/orleans.runtime.grainid/)
- [IChannelNamespacePredicate](/orleans/docs/api/csharp/microsoft.orleans.broadcastchannel/orleans.broadcastchannel.ichannelnamespacepredicate/) - Stream namespace predicate used for filtering implicit subscriptions using [ImplicitChannelSubscriptionAttribute](/orleans/docs/api/csharp/microsoft.orleans.broadcastchannel/orleans.implicitchannelsubscriptionattribute/).
- [IChannelNamespacePredicateProvider](/orleans/docs/api/csharp/microsoft.orleans.broadcastchannel/orleans.broadcastchannel.ichannelnamespacepredicateprovider/) - Converts predicate pattern strings to [IChannelNamespacePredicate](/orleans/docs/api/csharp/microsoft.orleans.broadcastchannel/orleans.broadcastchannel.ichannelnamespacepredicate/) instances.
