ServiceDownload Method (Int32, String, GeometryBase, SpatialRel, String, Boolean, Int32)

PreStorm - A Data Client for ArcGIS Server REST API

Downloads and yields features whose attributes and geometry are dynamically accessed at runtime. Possibly throws RestException.

Namespace: PreStorm
Assembly: PreStorm (in PreStorm.dll) Version: 1.8.19.0 (1.8.19.0)

Syntax

Copy

public IEnumerable<DynamicFeature> Download(
	int layerId,
	string whereClause,
	GeometryBase geometry,
	SpatialRel spatialRel,
	string extraParameters = null,
	bool keepQuerying = false,
	int degreeOfParallelism = 1
)

Public Function Download ( 
	layerId As Integer,
	whereClause As String,
	geometry As GeometryBase,
	spatialRel As SpatialRel,
	Optional extraParameters As String = Nothing,
	Optional keepQuerying As Boolean = false,
	Optional degreeOfParallelism As Integer = 1
) As IEnumerable(Of DynamicFeature)

Parameters

layerId: Type: SystemInt32
The layer ID of the feature layer or table.
whereClause: Type: SystemString
The where clause. If set to null, returns all features.
geometry: Type: PreStormGeometryBase
The geometry used to spatially filter the records.
spatialRel: Type: PreStormSpatialRel
The spatial relationship used for filtering.
extraParameters (Optional): Type: SystemString
The query string that describes any additional query parameters (i.e. outSR=4326). Each parameter must be url encoded.
keepQuerying (Optional): Type: SystemBoolean
If set to true, repetitively queries the server until all features have been returned.
degreeOfParallelism (Optional): Type: SystemInt32
The maximum number of concurrent requests.
