ShiftAmount Property

Summary

Gets the value that the MinimumToZeroCommand class object uses to shift the negative values so that the minimum negative value will be zero.

Syntax

Objective-C

C++/CLI

Java

Python

public int ShiftAmount { get; }

@property (nonatomic, assign, readonly) NSUInteger shiftAmount;

public int getShiftAmount();

public: 
property int ShiftAmount { 
   int get(); 
}

ShiftAmount # get  (MinimumToZeroCommand)

Property Value

Value that the MinimumToZeroCommand class object uses to shift the negative values so that the minimum negative value will be zero.
