// BLADE PROTOCOL HANDLERS
|
||||
// This is where the real work happens for the blade protocol, where routing is done based on the specific intent of the given message, these exist here to simplify
|
||||
// access to the internals of the blade_handle_t where all the relevant data is stored
|
||||
// Each jsonrpc method for the blade protocol will require 3 functions: a request generator, a request handler, and a response handler
|
||||
// Responses can be generated internally and are not required for an isolated entry point, in the case of further external layers like blade.execute, they will be
|
||||
// handled within the blade protocol handlers to dispatch further execution callbacks, however each jsonrpc exposed to support the blade protocols may deal with
|
||||
// routing in their own ways as they have different requirements for different blade layer messages.
|
||||
|
||||
|
||||
// blade.publish notes
|
||||
// This jsonrpc is used to notify the master of a new protocol being made available, the purpose of which is to make such protocols able to be located by other nodes with
|
||||
// only minimal information about the protocol, particularly it's registered name, which is most often the main/only namespace for the protocols methods, however it is
|
||||
// possible that additional namespaces could be included in this publish as well if the namespaces are defined separately from the protocol name, and the protocol name could
|
||||
// result in an implicitly created namespace in addition to any others provided.
|
||||
// Routing Notes:
|
||||
// When routing a publish request, it only needs to travel upstream to the master node for processing, however in order to receive a publish response the original request
|
||||
// and response must carry a nodeid for the requesting node (requester-nodeid), technically the master does not need to be provided, but for posterity and consistency
|
||||
// the master nodeid can be provided in whatever is used for the responder of a request (responder-nodeid).
|
||||
// By using requester-nodeid and responder-nodeid, these do not need to be swapped in the response, they can simply be copied over, and the routing looks at the
|
||||
// appropriate field depending on whether it is handling a request or a response to determine the appropriate downstream nodeid
|
||||
|
||||
|
||||
// blade.publish request generator
|
||||
// @todo add additional async callback to be called upon a publish response to inform caller of the result?
