Summary

Replacement for the C++ ternary conditional operator.

Pascal

 function Iff(const Condition: Boolean; const TruePart: string; const FalsePart: string): string; overload;
function Iff(const Condition: Boolean; const TruePart: Char; const FalsePart: Char): Char; overload;
function Iff(const Condition: Boolean; const TruePart: Byte; const FalsePart: Byte): Byte; overload;
function Iff(const Condition: Boolean; const TruePart: Integer; const FalsePart: Integer): Integer; overload;
function Iff(const Condition: Boolean; const TruePart: Cardinal; const FalsePart: Cardinal): Cardinal; overload;
function Iff(const Condition: Boolean; const TruePart: Float; const FalsePart: Float): Float; overload;
function Iff(const Condition: Boolean; const TruePart: Boolean; const FalsePart: Boolean): Boolean; overload;
function Iff(const Condition: Boolean; const TruePart: Pointer; const FalsePart: Pointer): Pointer; overload;
function Iff(const Condition: Boolean; const TruePart: Int64; const FalsePart: Int64): Int64; overload;
function Iff(const Condition: Boolean; const TruePart: Variant; const FalsePart: Variant): Variant; overload;

Parameters

Parameters	Description
const Condition: Boolean	The expression which determines which of the other parameters is returned as the function result.
const TruePart: string	The function result if Condition evaluates to True.
const FalsePart: string	The function result if Condition evaluates to False.

Return Value

If Condition evaluates to True TruePart is returned, otherwise FalsePart is returned.

Description

Iff is a replacement for the C/C++ ternary conditional operator ?:. It evaluates the specified boolean expression and depending on the outcome returns either the specified TruePart or FalsePart parameter. The difference to the C/C++ operator is that both expressions are evaluated.
