Declaration

Source position: variants.pp line 278

var NullStrictConvert: Boolean = True;

Description

NullStrictConvert determines what to do when typecasting a Null value to another type: If it is True then an exception will be raised using VarCastError. If it is False then a sensible default is used: 0 or some variation on 0 based on the type of the variant. For string values the NullAsStringValue is used.
