declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

resultRows Array<Array<(Path|GraphObject|Geometry|Date|string|number|null|Array<(Path|GraphObject|Geometry|Date|string|number|null)>)>>

An array of the result types that are returned from a search or query. Each item in the resultRows array matches the search or query constraints.

Examples

// Example of GraphQueryResult.resultRows returned from a
// `MATCH (n:Supplier)-[r]->(m) RETURN [n.id, n.geometry, n, r, m], {var1: n}`
// query on a knowledge graph that contains supply chain information
KnowledgeGraphModule.executeQuery(
 knowledgeGraph, //graph
 { //searchArguments
   openCypherQuery: "MATCH (n:Supplier)-[r]->(m) RETURN [n.id, n.geometry, n, r, m], {var1: n}",
  }).then((queryResult) => {
    //do something with the result
   console.log(queryResult)
});

//sample result of the above query
"resultRows": [
 [ //array of result types that meet query criteria
   [ //single return type that matches query return format.
     1111,
     "Point",
     {  //Supplier Entity

         "Name": "Queen City Steel",
       },
       "typeName": "Supplier",

Method Overview

Method Details

addHandles(handleOrHandles, groupKey)inherited

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle[] Handles marked for removal once the object is destroyed.

groupKey * optional Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

hasHandles(groupKey){Boolean}inherited

Returns true if a named group of handles exist.

Parameter

groupKey * optional A group key.

Returns

Type	Description
Boolean	Returns true if a named group of handles exist.

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles(groupKey)inherited

Removes a group of handles owned by the object.

Parameter

groupKey * optional A group key or an array or collection of group keys to remove.

Example

obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");
