示例1:
connection.commit(function(res, res_err) {
if (res_err) {
// Should be automatically rollbacked
console.log("Failed to commit data " + res_err);
graph.Rollback();
return;
}
graph.CommitTransaction();
message.reply(JSON.stringify({ status: 200, data: { version: graph.GetVersion() }, error: null }));
for (let ev in events) {
eb.publish("projects.events." + projectId, JSON.stringify(ev));
}
return;
});
示例2: function
var applyCommand = function(index) {
if (index == 0) {
graph.BeginTransaction();
}
if (index === commands.length) {
connection.commit(function(res, res_err) {
if (res_err) {
// Should be automatically rollbacked
console.log("Failed to commit data " + res_err);
graph.Rollback();
return;
}
graph.CommitTransaction();
message.reply(JSON.stringify({ status: 200, data: { version: graph.GetVersion() }, error: null }));
for (let ev in events) {
eb.publish("projects.events." + projectId, JSON.stringify(ev));
}
return;

} else {
try
{
let comm = commands[index];

[graph.GetVersion(), event.toJson()],
function (res, res_err) {
if (res_err) {
console.log("Inserting event failed " + res_err);
rollback(new Error("Internal server error"), index);
return;
}
events.push(event);

// This catch block is for the graph.ApplyCommand, not for the DB query
// see (https://www.joyent.com/developers/node/design/errors#fn:1)
} catch (error) {

}
}
示例3: function

vertx.close();
return;
}
let results = res.results;
Array.prototype.forEach.call(results, function(row) {
let event = row[0];
graph.ApplyEvent(JSON.parse(event));
});
message.reply(JSON.stringify(graph.GetGraph().serialize()));
});
