I get a Relationship after a query with the Nebula Graph Java client, and then the properties of the relationship are written to map, shown as below:
Map<String, ValueWrapper> props = ((Relationship) value).properties()
Then I want to add src_vid, dst_vid, and rank, shown as below:
props.put(“srcVid”, ((Relationship) cvtedValue).srcId());
props.put(“dstVid”, ((Relationship) cvtedValue).dstId());
props.put(“rank”, ((Relationship) cvtedValue).ranking());
But the last rank cannot be added to the map because it's a long value.
Is there a way to convert it to value wrapper?
Try Long → Value → ValueWrapper
new ValueWrapper(new Value(Value.IVAL, 10L), “utf-8”, 28800))

This My code
Map<Strig,Object> map
so inside **map** object having value like this
{id=123, type=V, bn={type=P, value=MCD}, s=[{type=p, dsId=udi, s={type=p, value=SM}, value=55}, {type=P, dsId=psg, s={type=P, value=GPS}, value=11}, {type=P, source={type=P, value=CAMM}, value=10}]}
i want to be reomve some specfic value from this Map so My
desire output should be like this
{id=123, type=V, bn=MCD, s=[{dsId=udi, s={value=SM}, value=55}, { dsId=psg, s={value=GPS}, value=11}, {source={value=CAMM}, value=10}]}
So Map<String,Object> map representation should be above like of code
Here i want to do response optimization so please help me how to do this .
the following is my problem:
I do a select on my database and want to write the values of every record i get in a map. When i do this, i only have the values of one record in my map, because the put() function overwrites the entries everytime the loop starts again. Since I have to transfer the Key:Value pairs via JSON into my Javascript and write something into a field for every Key:Value pair, an ArrayList is not an option.
I've already tried to convert a ArrayList, which contains the Map, to a Map or to a String and then to Map, but i failed.
EDIT:
Here´s my Code
def valueArray = new ArrayList();
def recordValues = [:]
while (rs.next())
{
fremdlKorr = rs.getFloatValue(1)
leistungKorr = rs.getFloatValue(2)
materialKorr = rs.getFloatValue(3)
strid = rs.getStringValue(4)
recordValues.put("strid", strid);
recordValues.put("material", materialKorr);
recordValues.put("fremdl", fremdlKorr);
recordValues.put("leistung", leistungKorr);
valueArray.add(korrekturWerte);
}
The ArrayList was just a test, i dont want to have an ArrayList, i need a Map.
The code as written, will give you a list of maps, but the maps will all contain the values of the last row. The reaons is the def recordValues = [:] that is outside of the while loop. So you basically add always the same map to the list and the map values get overwritten each loop.
While moving the code, would fix the problem, I'd use Sql instead. That all boils down to:
def valueArray = sql.rows("select strid, material, fremdl, leistung from ...")
For my data model, I have the following:
type defines an item
The project owns an item
Type is connected to anchors (Suppose the anchor is country)
Item is connected to a particular anchor instance (anchor instance
will have corresponding value for anchor, suppose US)
I am trying to read an item along with the type, anchorNames and anchorValues.
Following is the query I have written:
g.V().hasLabel('Type').as('t')
.outE('DEFINES').inV().hasLabel('Item').has('dataId',’test-id').has('version','1').as('i')
.inE('OWNS').outV().hasLabel('Project').select('i')
.project('i','t','anchorNames','anchorValues')
.by(__.valueMap(true))
.by(__.in().hasLabel('Type').valueMap(true))
.by(out().in().hasLabel('Anchor').values('name').fold())
.by(out().as('AnchorInstance').select('AnchorInstance')
.by(values('value','secondaryValue').fold()).fold())
I get i and t but the result for anchorNames and anchorValues is as follows:
{anchorNames=[status, status, country], anchorValues=[[OK], [US], [FAIL]]}
However I am expecting the following:
{anchorNames=[status, status, country], anchorValues=[[OK], [FAIL], [US]]}
I need the ordering between the anchorNames and anchorValues as shown above.
I think the best approach will be to get the name and the corresponding values together.
g.V().hasLabel('Type').as('t')
.out('DEFINES').hasLabel('Item').has('dataId',’test-id').has('version','1').as('i')
.in('OWNS').hasLabel('Project').select('i')
.project('i','t','anchors')
.by(__.valueMap(true))
.by(__.in().hasLabel('Type').valueMap(true))
.by(out().project('anchorNames','anchorValues')
.by(__.in().hasLabel('Anchor').values('name'))
.by(values('value','secondaryValue').fold()).fold())
Required suggestion on below part.please any one give solution.
We have mapping from 850 to FlatFile
X12/PO1Loop1/PO1/PO109 and I need to map to field VALUE which is under record Option which is unbounded.
Split PO109 into substrings delimited by '.', foreach subsring after the first, create new Option with value=substring
So in input sample we have value like 147895632qwerqtyuui.789456123321456987
Similarly the field repeats under POLoop1.
So I need to split value based on (.) then pass a value to value field under option record(unbounded).
I tried using below code snippet
public string SplitValues(string strValue)
{
string[] arrValue = strValue.Split(".".ToCharArray());
foreach (string strDisplay in arrValue)
{
return strDisplay;
}
}
But it doesn't works, and I am not really familiar with the String methods and I am not sure if there's an easy way to do this. I have a String which contains couple of values delimited with "." .
So I need to separate values based on delimiter(.) and pass value to field.
How can I do this
As I mentioned, not too clear what is your objective, but I think you want to split a node that has some kind of delimiter into multiple nodes... if so, Try this: https://seroter.wordpress.com/2008/10/07/splitting-delimited-values-in-biztalk-maps/
He is doing exactly that. Given a node with a|b|c|d as value, output multiple nodes, each containing the value after splitted by |, so node1 = a, node2 = b, node3 = c, node4 = d.
Given a basic Blueprints-compatible OrientGraph with Index 'name' (unique or notunique), any suggestions for how the following could be improved, if needs be?
Note: I can't find a definitive guide to load a [blueprints] vertex using index. I have a large graph and using has('name','bob') (in console) takes 2 minutes! On the other hand, an index-based search returns in milliseconds.
The best I've come up with so far:
OrientGraph graph = new OrientGraph("local:/graph1/databases/test", "admin", "admin");
List<ODocument> resultlist = graph.getRawGraph().query(new OSQLSynchQuery<ODocument>("SELECT FROM INDEX:name WHERE KEY = 'bob'"));
ODocument resultodoc = resultlist.get(0).field("rid");
String rid = resultodoc.getIdentity().toString(); // would return something like #6:1500000
Vertex v1 = graph.getVertex(rid);
System.out.println(v1.getProperty("name"));
OrientDB supports the IndexableGraph interface. To use it take a look at:
