Property Details

declaredClassStringreadonly inherited
Since: ArcGIS API for JavaScript 4.7

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

definitionExpressionString

The definition expression to be applied to the related table or layer. Only records that fit the definition expression and are in the list of objectIds will be returned.

gdbVersionString
Since: ArcGIS API for JavaScript 4.7

Specify the geodatabase version to display.

geometryPrecisionNumber

Specify the number of decimal places for the geometries returned by the query operation.

historicMomentDate
Since: ArcGIS API for JavaScript 4.7

The historic moment to query. This parameter applies only if the supportsHistoricMoment property of the layers being queried is set to true.

maxAllowableOffsetNumber

The maximum allowable offset used for generalizing geometries returned by the query operation. The offset is in the units of outSpatialReference. If outSpatialReference is not defined, the spatial reference of the map is used.

objectIdsNumber[]

A comma delimited list of ObjectIds for the features in the layer/table being queried.

outFieldsString[]

Attribute fields to include in the FeatureSet. Fields must exist in the map layer. You must list actual field names rather than the alias names. You are, however, able to use the alias names when you display the results. You can set field alias names in the map document.

When specifying the output fields, you should limit the fields to only those you expect to use in the query or the results. The fewer fields you include, the faster the response will be.

Each query must have access to the Shape and ObjectId fields for a layer. However, your list of fields does not need to include these two fields.

Example:
query.outFields = [ "NAME", "STATE_ABBR", "POP04" ];
outSpatialReferenceSpatialReferenceautocast

The spatial reference for the returned geometry. If not specified, the geometry is returned in the spatial reference of the map.

relationshipIdNumber

The ID of the relationship to test. The ids for the relationships the table or layer participates in are listed in the ArcGIS Services directory.

returnGeometryBoolean

If true, each feature in the FeatureSet includes the geometry. Set to false (default) if you do not plan to include highlighted features on a map since the geometry makes up a significant portion of the response.

Default Value:false

Method Details

Since: ArcGIS API for JavaScript 4.7

Creates a deep clone of RelationshipQuery object.

Returns:
TypeDescription
RelationshipQueryA new instance of a RelationshipQuery object equal to the object used to call .clone().
fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from a product in the ArcGIS platform. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameter:
json Object

A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns:
TypeDescription
*Returns a new instance of this class.
toJSON(){Object}
