PurityEdge (Soot - a J*va Optimization Framework 4.6.0 API)

java.lang.Object
- soot.jimple.toolkits.annotation.purity.PurityEdge

```
public class PurityEdge
extends Object
```
An edge in a purity graph. Each edge has a source PurityNode, a target PurityNode, and a field label (we use a String here). To represent an array element, the convention is to use the [] field label. Edges are immutable and hashable. They compare equal only if they link equal nodes and have equal labels.
