CommandCaller

The client of the other contexts' HTTP command gateways, which the host gives a node, a port the runtime consumes and wow-client's HttpCommandCaller implements: it sends a call to the gateway of its command's context, at the address the host configures for it, and returns the result the target answers, at COMMITTED: SUCCEEDED, REJECTED or FAILED. It throws a WowProblemException when it reaches no result (the target down, unreachable or late, no address for the context), retryable with the same request id.

Functions

call

abstract suspend fun call(call: OutgoingCall): CommandResult

reaches

open fun reaches(context: String): Boolean

Whether it knows where to call context's gateway: a node whose sagas call a context its caller does not reach is not built. The default answers true; the host's HTTP caller (wow-client's HttpCommandCaller) answers whether its endpoints give context an internal URL.
