Description
Calculates the difference of two geometries.
Usage
You may need to find the difference between two geometries. You could find the difference in geometries and then use the Calculate Area or Calculate Length activity to find out how much larger one geometry is than the other.
Inputs
Geometry 
Required Type: esri.Geometry (3.x, 4.x)*  esri.Geometry[] (3.x, 4.x)* The input geometry to subtract from. 
Subtractor 
Optional Type: esri.Geometry (3.x, 4.x)* The geometry being subtracted from inclusion. 
Symmetric 
Optional Type: Boolean Whether the difference is symmetric or not. If true, the symmetric difference between leftGeometry and rightGeometry is returned. Otherwise, rightGeometry is subtracted from leftGeometry. 
* Geocortex Workflow uses different versions of Esri's ArcGIS API for JavaScript depending on the type of host application. See Underlying Technologies for information.
Outputs
geometry 
Type: esri.Geometry (3.x, 4.x)* The first difference result. 
results 
Type: esri.Geometry[] (3.x, 4.x)* The difference results.
