// SignalRecipient serves two purposes:
|
||
|
|
//
|
||
|
|
// a) It serves as a cache of "known" Signal accounts. When the service indicates
|
||
|
|
// that an account exists, we make sure that an instance of SignalRecipient exists
|
||
|
|
// for that recipient id (using mark as registered) and has at least one device.
|
||
|
|
// When the service indicates that an account does not exist, we remove any devices
|
||
|
|
// from that SignalRecipient - but do not remove it from the database.
|
||
|
|
// Note that SignalRecipients without any devices are not considered registered.
|
||
|
|
//// b) We hang the "known device list" for known signal accounts on this entity.
