Gets a value of a data object property.

In some cases getting values of data objects through the IDataField interface may be a costly operation because it occurs through the reflection. To accelerate the values getting, the data objects may implement IGetAccelerator interface. In this case the values are returned through the delegating mechanism and not through the reflection.

            //This implementation directly calls the DoubleValue method and returns the result
