ParamVertex (com.ibm.wala.cast.js 1.6.0 API)

java.lang.Object
- com.ibm.wala.cast.js.callgraph.fieldbased.flowgraph.vertices.Vertex
- - com.ibm.wala.cast.js.callgraph.fieldbased.flowgraph.vertices.ParamVertex

```
public class ParamVertex
extends Vertex
```
A parameter vertex represents a positional parameter of a function. It doesn't necessarily need to correspond to a named parameter.
Numbering of positional parameters is 1-based, with parameter 0 being the this value.
A named parameter is an ordinary SSA variable, hence it is represented as a VarVertex. The flow graph builder sets up edges between parameter vertices and their corresponding variable vertices for named parameters.

    Description copied from class: Vertex
    
    If possible, returns a String representation of this that refers to source-level entities rather thatn WALA-internal ones (e.g., source-level variable names rather than SSA value numbers). By default, just returns the results of Object.toString()
    
    Overrides:
    
    toSourceLevelString in class Vertex
