- com.ibm.wala.escape.TrivialMethodEscape

All Implemented Interfaces:

IMethodEscapeAnalysis, INodeEscapeAnalysis
```
public class TrivialMethodEscape
extends Object
implements IMethodEscapeAnalysis, INodeEscapeAnalysis
```
Trivial method-level escape analysis. An instance does not escape from method m if the following hold:
1. the instance is only ever pointed to by locals (it is never stored in the heap)
2. the method m does NOT return (either normally or exceptionally) a pointer to the instance
