Inheriting from existing data types

Visual Programming User Guide : Introduction to Visual Programming : Validating user input : Creating your own data types : Inheriting from existing data types

When you create your own data types, try to inherit from the data types that VA Smalltalk provides. This way, the code you write is simpler, because you don't have to check for all the error conditions that VA Smalltalk already checks for. You can inherit from any of the following VA Smalltalk classes:

Data type	Class
Boolean	AbtBooleanConverter
Character	AbtCharacterConverter
Date	AbtDateConverter
DBCS Only	AbtDbStringOnlyConverter
Decimal	AbtDecimalConverter
Float	AbtFloatingPointRepresentationConverter
Integer	AbtIntegerConverter
Monetary Amount	AbtMonetaryAmountConverter
Number	AbtNumberConverter
Social Security Number	AbtSSNConverter
String	AbtStringConverter
Time	AbtTimeConverter
Timestamp	AbtTimestampConverter
USA State	AbtUSAStateConverter
Zip Code	AbtZipCodeConverter
