Parameters
MaxRecordCount System.Int32
The maximum number of records that will be returned for a given query.
SupportsCacheHint System.Boolean
Indicates if the query operation supports a cache hint. This is valid only for hosted feature services.
SupportsCentroid System.Boolean
Indicates if the geometry centroid associated with each polygon feature can be returned.
SupportsDisjointSpatialRelationship System.Boolean
Indicates if the query operation supports disjoint spatial relationship. This is valid only for hosted feature services.
SupportsDistance System.Boolean
Indicates if the layer’s query operation supports a buffer distance for input geometries.
SupportsDistinct System.Boolean
Indicates if the layer supports queries for distinct values based on fields specified in the outFields.
SupportsExtent System.Boolean
Indicates if the layer’s query response includes the extent of features.
SupportsGeometryProperties System.Boolean
Indicates if the layer’s query response contains geometry attributes, including shape area and length attributes.
SupportsHavingClause System.Boolean
Indicates if the layer supports the having clause on the service.
SupportsHistoricMoment System.Boolean
Indicates if the layer supports historic moment query.
SupportsOrderBy System.Boolean
Indicates if features returned in the query response can be ordered by one or more fields.
SupportsPagination System.Boolean
Indicates if the query response supports pagination.
SupportsPercentileStatistics System.Boolean
Indicates if the layer supports percentile statisticType.
SupportsQuantization System.Boolean
Indicates if the query operation supports the projection of geometries onto a virtual grid.
SupportsQuantizationEditMode System.Boolean
Indicates if the query operation supports quantization designed to be used in edit mode (highest resolution at the given spatial reference).
SupportsQueryGeometry System.Boolean
Indicates if the query response includes the query geometry.
SupportsResultType System.Boolean
Indicates if the number of features returned by the query operation can be controlled.
SupportsStandardizedQueriesOnly System.Boolean
Indicates if the layer supports using standardized queries. Learn more about standardized queries here.
SupportsStatistics System.Boolean
Indicates if the layer supports field-based statistical functions.
SupportsSqlExpression System.Boolean
Indicates if the layer supports SQL expressions.
SupportsSpatialAggregationStatistics System.Boolean
Indicates if the layer supports spatial extent, center or convex hull to be returned for each distinct group when groupByFieldsForStatistics is used. Supported with ArcGIS Online hosted features services only.
