      This method is similar to `propX(Expression, Expression)` but will make sure that if the property being accessed is defined inside the classnode provided as a parameter, then a getter call is generated instead of a field access.
      Parameters:
        `annotatedNode` - the class node where the property node is accessed from
        `pNode` - the property being accessed
      Returns:
        a method call expression or a property expression

                                           PropertyNode pNode)

      This method is similar to `propX(Expression, Expression)` but will make sure that if the property being accessed is defined inside the classnode provided as a parameter, then a getter call is generated instead of a field access.
      Parameters:
        `annotatedNode` - the class node where the property node is accessed from
        `receiver` - the object having the property
        `pNode` - the property being accessed
      Returns:
