Summary

Determines if the data object actually represents a value.

Pascal

 functionHasValue: Boolean; override;

Description

HasValue determines if the data object represents a value. This is dependent on the data the object is representing and therefor changes for each data class. If the data object represents a value, HasValue returns True, otherwise False is returned. If HasValue is False, data can not be read or written and the inspector will show (no value).
