Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static java.lang.Object`	`getIdFromSpecificReferenceValue(ReferenceValue value)`	Returns the identifier of a reference value for which `Value.isSpecific()` is true (i.e., the reference is identified by a unique number).
`static Value`	`getStackBefore(PartialEvaluator partialEvaluator, int offset, int index)`	Returns the value from the before stack at offset, counting from the top.
`static Value`	`getStackValue(Stack stack, int indexFromTop)`	Returns the value from the stack, counting from the top of the stack.

- Method Detail
  - getStackValue
```
public static Value getStackValue(Stack stack,
                                  int indexFromTop)
```
    Returns the value from the stack, counting from the top of the stack. If the stack does not contain that many elements, returns null.
  - getStackBefore
```
public static Value getStackBefore(PartialEvaluator partialEvaluator,
                                   int offset,
                                   int index)
```
    Returns the value from the before stack at offset, counting from the top. If the stack does not contain that many elements, returns null.
  - getIdFromSpecificReferenceValue
```
public static java.lang.Object getIdFromSpecificReferenceValue(ReferenceValue value)
```
    Returns the identifier of a reference value for which Value.isSpecific() is true (i.e., the reference is identified by a unique number).
    This helper method is needed because IdentifiedReferenceValue and IdentifiedArrayReferenceValue do not share the relevant portion of the class hierarchy, but a better solution should be implemented in the future.
