- Method Detail
  - getExpression
```
public AbstractEncapsulatedExpression getExpression()
```
    Returns the actual parsed object if this StateObject representation of the JPQL query was created by parsing an existing JPQL query.
    
    Specified by:
    
    getExpression in interface StateObject
    
    Overrides:
    
    getExpression in class AbstractStateObject
    
    Returns:
    
    The parsed object when a JPQL query is parsed and converted into a StateObject or null when the JPQL query is manually created (i.e. not from a string)
  - getIdentifier
```
public abstract String getIdentifier()
```
    Returns the JPQL identifier of the expression represented by this AbstractSingleEncapsulatedExpressionStateObject.
    
    Returns:
    
    The JPQL identifier that is shown before the left parenthesis
