default Traversal.Admin eval(Bytecode bytecode,
                             String traversalSource)
                      throws ScriptException
```
    Evaluates Traversal Bytecode against a traversal source in the global bindings of the ScriptEngine.
    
    Parameters:
    
    bytecode - of the traversal to execute
    
    traversalSource - to execute the bytecode against which should be in the available bindings.
    
    Throws:
    
    ScriptException
  - eval
```
Traversal.Admin eval(Bytecode bytecode,
                     Bindings bindings,
                     String traversalSource)
              throws ScriptException
```
    Evaluates Traversal Bytecode with the specified Bindings. These Bindings supplied to this method will be merged with global engine bindings and override them where keys match.
    
    Throws:
    
    ScriptException
