- Method Detail
  - getChangeExpression
```
@CheckForNull
ValueSpecification getChangeExpression()
```
    Returns the value of the 'Change Expression' containment reference. It is bidirectional and its opposite is 'change Event Of Change Expression'. A Boolean-valued ValueSpecification that will result in a ChangeEvent whenever its value changes from false to true.
    
    Returns:
    
    the value of the 'Change Expression' containment reference.

void setChangeExpression(@CheckForNull
                         ValueSpecification value)
```
    Sets the value of the 'Change Expression' containment reference.
    
    Parameters:
    
    value - the new value of the 'Change Expression' containment reference.
