LastCallToken (lisa-analyses 0.1 API)

java.lang.Object
- it.unive.lisa.interprocedural.context.LastCallToken

All Implemented Interfaces:

ContextSensitivityToken, it.unive.lisa.interprocedural.ScopeId
```
public class LastCallToken
extends java.lang.Object
implements ContextSensitivityToken
```
A context sensitive token representing a single ScopeToken. The token that is kept is always the last pushed one, enabling the analysis of infinite call chains by lubbing results obtained starting from the same call site, regardless of the call stack. This corresponds to having a KDepthToken with k = 1.
