## Classes
class | MessageFilter
| Assigns systems to FilterSets. Each FilterSet limits what kinds of messages are allowed. The MessageFilter plugin is used for security where you limit what systems can send what kind of messages. You implicitly define FilterSets, and add allowed message IDs and RPC calls to these FilterSets. You then add systems to these filters, such that those systems are limited to sending what the filters allows. You can automatically assign systems to a filter. You can automatically kick and possibly ban users that stay in a filter too long, or send the wrong message. Each system is a member of either zero or one filters. Add this plugin before any plugin you wish to filter (most likely just add this plugin before any other). More...
