public ProgramVertexProgramStep(Traversal.Admin traversal,
                                VertexProgram vertexProgram)
```
- Method Detail
  - generateProgram
```
public VertexProgram generateProgram(Graph graph,
                                     Memory memory)
```
    Description copied from interface: VertexComputing
    
    Generate the VertexProgram.
    
    Parameters:
    
    graph - the Graph that the program will be executed over.
    
    memory - the Memory from the previous OLAP job if it exists, else its an empty memory structure.
    
    Returns:
    
    the generated vertex program instance.
  - getRequirements
```
public Set<TraverserRequirement> getRequirements()
```
    Description copied from interface: Step
    
    Provide the necessary TraverserRequirement that must be met by the traverser in order for the step to function properly. The provided default implements returns an empty set.
    
    Returns:
    
    the set of requirements
  - hashCode
