      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

      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:

      Converts an expression into the String source. Only some specific expressions like closure expression support this.
      Parameters:
        `readerSource` - a source
        `expression` - an expression. Can't be null
      Returns:
        the source the closure was created from
      Throws:
        `IllegalArgumentException` - when expression is null
        `Exception` - when closure can't be read from source
