```
public abstract class JvmMemoryLocation
extends java.lang.Object
```
A JvmMemoryLocation points at a specific location in a certain state of the Jvm. For example a JvmStackLocation with index 0 indicates the top of the stack.

- Method Detail
  - extractValueOrDefault
```
public abstract <T extends LatticeAbstractState<T>> T extractValueOrDefault(JvmAbstractState<T> jvmState,
                                                                            T defaultValue)
```
    Given a JVM state, extract its content in the position represented by this JvmMemoryLocation.
    
    Type Parameters:
    
    T - The type of the states contained in the JVM state. e.g., for taint analysis this would be a SetAbstractState containing the taints and for value analysis a ValueAbstractState.
    
    Parameters:
    
    jvmState - The state from which the value is extracted.
    
    defaultValue - The value returned if it's not possible to extract the value.
    
    Returns:
    
    The value from the JVM abstract state for the memory location represented by this object. Or default value if not possible.
