AggregatingLayer.GenerateConvexHulls Property
Gets or sets a value that determines whether convex hulls representing the hierarchical topography are generated.
Syntax
public System.Boolean GenerateConvexHulls { get; set; }Property Value
Default: false
True to generate convex hull polygons; otherwise, False.
Remarks
When this property is True the MemoryDataSet that contains the features aggregated by the layer will also return features that represent the convex hull of each feature and its descendants in a hierarchy:
The convex hull of a single feature without children is represented by a point feature.
The convex hull of two features, for example a parent with a single child, is represented by a line feature.
The convex hull of more than two features is represented by a polygon feature.
The convex hulls are generated from the features in the hierarchy regardless of whether they are visible or not.
Each convex hull feature will also have the following attributes:
convexHullId set to the value of the IdAttribute attribute of the feature the convex hull was generated from.
convexHullDepth set to the feature's depth in the hierarchy. The depth of a root feature (one not having a parent) is zero and each descendant level increases the depth by one.
