All Implemented Interfaces:

InteractionListener, ExpressionSourceStackMonitor
```
public class PerspectiveTransformExpression
extends PerspectiveExpression
```
A PerspectiveExpression which has an additional execute(QualifiedValue) method to handle updating the underlying Expression with the incoming value and subsequently executing the expression which may be bound to the incoming value.

```
    Factory method for creating the PerspectiveTransformExpression
    
    Parameters:
    
    context - The BindingContext
    
    source - The expression source as a String
    
    Returns:
    
    The new PerspectiveTransformExpression
    
    Throws:
    
    ConfigurationException - If there was a problem creating the new PerspectiveTransformExpression
  - execute
```
public QualifiedValue execute(QualifiedValue input)
                       throws ExpressionException
```
    Passes the input QualifiedValue to the updated value consumer and then executes the underlying PerspectiveExpression
    
    Throws:
    
    ExpressionException
