Property Details

declaredClassStringreadonly inherited

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.

geometryPrecisionNumber

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

maxAllowableOffsetNumber

The maximum allowable offset used for generalizing geometries returned by the query operation. The offset is in the units of the 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 that you want to query.

outFieldsString[]

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

When you specify 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, but your list of fields does not need to include these two fields.

outSpatialReferenceSpatialReference

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.
