<Map> map Optional Reference to the map object.

* Required when showChooseExtent is true.
<FeatureLayer[]> originsLayers Required The point feature layers containing the origin points. The point features in these layers must have unique identifiers that correspond with unique identifiers in the destination points.
<String> outputLayerName Optional The name of the output layer to be shown in the Result layer name input box.

Method Details

cancel(jobInfo)

Cancels an analysis job that is being processed.
Parameters:
<Object> jobInfo Required An object containing job information including job ID, status, message, etc returned by the job-status event.

checkJobStatus(jobId)

Starts checking the analysis job status for the given jobId. (Added at v3.12)
Parameters:
<String> jobId Required Job id of the analysis job to check.

execute(params)

Starts an analysis tool.
Parameters:
<String> params Required See the object specifications table below for the structure of the params object.
Object Specifications:
<params>
<Object> itemParams Optional Parameters for creating the output service item. Refer to the ArcGIS REST API - Add Item help topic for a list of available parameters. Only used when the analysis task creates a hosted service.
<Object> jobParams Required The input job parameters. Required parameters vary from class to class. Refer to the Analysis REST API Documentation for details (Under the Request Parameters section of each task). When creating a hosted service, a layer name is required.
Sample:
var params = {
  itemParams: {
    description: "Item description.",
    snippet: "A short summary about this item.",
    tags: "<tag1>, <tag2>, <tag3>, ... ",

    ...
  }
}

analysisBase.execute(params);

getCreditsEstimate(toolName, jobParams)

Gets credits estimate for a specific analysis job. This method returns a deferred object. The callback function has an object containing the number of records to be processed and the estimated credit cost for this job.
Return type: Deferred
Parameters:
<String> toolName Required The name of the analysis tool from which a credits estimate will be returned.
<String> jobParams Required The input job parameters. This value should be the same as the jobParams property of an analysis tool dijit. Refer to the jobParams property of this class for detailed syntax.

analysisBase.getCreditsEstimate("FindHotSpots",{
  AnalysisLayer: layer._json,

}).then(function(result){
  console.log(result);
});
