the class ProcessManagerRepository method dispatchCommand.

/**
     * Dispatches the command to a corresponding process manager.
     *
     * <p>If there is no stored process manager with such an ID,

     *
     * @param envelope a request to dispatch
     * @see CommandHandlingEntity#dispatchCommand(CommandEnvelope)

}

Example 3 with CommandClass

use of io.spine.type.CommandClass in project core-java by SpineEventEngine.

the class CommandDispatcherRegistry method checkNotAlreadyRegistered.

     * already registered for dispatched in this command bus.
     *
     * @throws IllegalArgumentException if at least one command class already has
