11 Bus Attachments, Objects, Proxy Objects An application needs a Bus Attachment to communicate with the bus - Bus Attachments provide a root (/) for the object hierarchy Bus Objects implement interfaces - Bus Objects path names look like file paths, e.g. /org/alljoyn/games/chess - Bus Object have methods than can be called remotely. - Bus Objects can emit signals Proxy Bus Objects are local representations of remote Bus Objects. - Applications use proxy bus objects to make method calls to remote objects. Application Application Bus Attachment Bus Attachment Event handler Proxy Object Bus Bus Object Tree 11
