Is there a client side Geometry Engine for JavaScript?
Since: ArcGIS API for JavaScript 4.0. A client-side geometry engine for testing, measuring, and analyzing the spatial relationship between two or more 2D geometries. If more than one geometry is required for any of the methods below, all geometries must have the same spatial reference for the methods to work as expected.
How does an ArcGIS API work in JavaScript?
Creates query parameters that can be used to fetch features that satisfy the layer’s current filters and definitions. The query object representing the layer’s filters and other definitions. Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product.
How does the featurefilter class in ArcGIS work?
This class defines parameters for setting a client-side filter on a layer view . Once a FeatureFilter object’s properties are defined, it can be used to set the filter property of the layer view. You can set filters by attributes, time, geometry and geometry with distance .
What is the name of the class in ArcGIS?
The declared class name is formatted as esri.folder.className. Specifies a search distance from a given geometry in a spatial filter. The units property indicates the unit of measurement. In essence, setting this property creates a buffer at the specified size around the input geometry.
How is clipped geometry calculated in ESRI geometryengine?
Calculates the clipped geometry from a target geometry by an envelope. The geometry to be clipped. The envelope used to clip. Indicates if one geometry contains another geometry. The geometry that is tested for the “contains” relationship to the other geometry. Think of this geometry as the potential container of the insideGeometry.
How are geometry and distance parameters specified in ESRI?
The geometry and distance parameters must be specified as either both arrays or both non-arrays. Never specify one as an array and the other a non-array. The specified distance (s) for buffering. NOTE: The geometry and distance parameters cannot be mixed. They must either both be specified as arrays, non-arrays, but never both.
How are geometries buffered in the ArcGIS API?
For example, if you pass an array of four geometries: [g1, g2, g3, g4] and an array with one distance: [d1], all four geometries will be buffered by the single distance value. If instead you use an array of three distances: [d1, d2, d3], g1 will be buffered by d1, g2 by d2, and g3 and g4 will both be buffered by d3.
