class helpers

Learn class helpers in Pascal with a construct-specific explanation, unique example, engineering boundary, and mastery check.

10 min read • Advanced

class helpers is a focused Pascal topic inside Units and Generics. This lesson explains the construct itself, the state or value it operates on, and the observable result it produces.

Read the example as a small executable experiment. Identify the exact syntax that belongs to class helpers, then change one input and predict the result before running it.

Topic-specific example

pascal-07-10-class-helpers.pas
pascal Try It Live 
type TStringHelper=class helper for string function Shout:string; end; function TStringHelper.Shout:string; begin Result:=UpperCase(Self); end;
Edge case / engineering note

class helpers has rules that are easy to miss when the example is copied mechanically. Check the feature-specific boundary shown by this construct: scope, mutability, evaluation order, type constraints, lifetime, error behavior, compile-time restrictions, or resource cleanup where applicable.
