    Parameters:
    propertyAtom - the property atom.
    newValue - the new string value for the property.
- Method Detail
  - doPostResolve
```
protected boolean doPostResolve()
```
    Returns if resolving of this reference should be done in post- (true) or pre-stage (false).
    Returns:
    false by default, i.e. always in first pre-stage.
  - getFixedTarget
```
protected TARGET getFixedTarget()
```
    Support for a fixed reference.
    Override to provide the support.
    Returns:
    The fixed reference to return in cases the target reference is needed, and also serves as a verification if a new reference should be created or not. Returning null causes normal behavior (default).
  - clearFixedTarget
```
protected void clearFixedTarget()
```
    Called to clear the fixed reference in case the reference is changed. This will revert back to normal processing.
    The "clone" method does not change to be overridden to clear the fixed target as this method is called during cloning.
    This method is called prior to calling "initializeReferenceClone()" during cloning.
    Override to provide the support. It is important to also implement this method along with "getFixedTarget".
  - getReferenceString
```
public ReferenceString getReferenceString()
```
    Gets the reference string.
  - setPropValue
```
public boolean setPropValue(java.lang.String newValue)
                     throws PropValidateException
```
    Sets a new value for this property. If any listener is present and the value has changed compare to the last value, the listener is informed.
    Parameters:
    newValue - the new value.
    Returns:
    boolean true for value has changed, false for same value as current value.
    Throws:
    PropValidateException - When the constraints are not met.

                      throws PropTypeException
```
    Validates that the value to set is of ReferenceString instance.

    Specified by:
    validatePropType in interface IGProp<TARGET extends IPropCnr>
    Specified by:
    validatePropType in class GProp<ReferenceString>
    Parameters:
    newValue - The new value to set.

  - getValueClasses
```
public java.lang.Class<?>[] getValueClasses()
```
    Gets the list of possible native Java classes that can be used to set a value using setPropertyValue, in order of importance. Note that loss of precision in data if e.g. an Float property accepts a Double. However, the setPropertyValue throws IllegalArgumentException if the range in invalid, e.g. conversion of a Integer to a Byte, and the value is not -127 to 128.
    Specified by:
    getValueClasses in interface IGProp<TARGET extends IPropCnr>
    Specified by:
    getValueClasses in class GProp<ReferenceString>

```
    Called when the property has been resolved. Subclasses override this method to implement some behavior. The default implementation performs nothing, i.e. there is no need to call super.informResolved().
  - informError
```
protected void informError()
```
    Called when the property has an error. Subclasses override this method to implement some behavior. The default implementation performs nothing, i.e. there is no need to call super.informError().
  - informClearError
```
protected void informClearError()
```
    Called when the property has been cleared from error. Subclasses override this method to implement some behavior. The default implementation performs nothing, i.e. there is no need to call super.informClearError().
  - validateReferenceScope
```
protected java.lang.String validateReferenceScope(TARGET target)
```
    Called when the a property container has been renamed or moved in order to perform validation of the reference, e.g. if a base property has been moved out of scope. The implementor can assign or clear property errors by returning the error string.
    Parameters:
    target - Target reference to validate the scope of, i.e. the referenced property.
    Returns:
    The error message, or null for valid. Default implementation returns null.
  - getReferenceDescription
```
public abstract java.lang.String getReferenceDescription()
```
    Gets a short description of this reference, e.g. "VirtualSpace" or "Label For".
    Specified by:
    getReferenceDescription in interface IPropReference
    Returns:
    The reference description string.
  - isReferenceValid
```
public abstract boolean isReferenceValid(GProp<?> property)
```
    Validates the property reference that has been looked up.
    Specified by:
    isReferenceValid in interface IPropReference
    Parameters:
    property - The property to validate.
    Returns:
    true if valid, false otherwise.
