Description

Attempts to set the value of the field with the given Variant value.

Descendants of TField that represent certain fields (fields that can hold any value specified through a Variant) can override the SetAsVariant method to set the value of the field with the given Variant Value.

If the given Value is Null, then the field is cleared. If SetAsVariant fails to set the field with the given Value, an exception is raised.
