Symbology Property

Summary

Gets or sets the barcode symbology (type) associated with this MicroQRBarcodeData.

Syntax

Objective-C

C++/CLI

Java

Python

public override BarcodeSymbology Symbology { get; set; }

@property (nonatomic, assign) LTBarcodeSymbology symbology;

@Override public BarcodeSymbology getSymbology() 
@Override public void setSymbology(BarcodeSymbology value)

[BrowsableAttribute(false)] 
public: 
property BarcodeSymbology Symbology { 
   BarcodeSymbology get() override; 
   void set (    BarcodeSymbology ) override; 
}

Symbology # get and set (MicroQRBarcodeData)

Property Value

An BarcodeSymbology enumeration member that specifies the barcode symbology (type) associated with this MicroQRBarcodeData.

Remarks

This property overrides the base BarcodeData.Symbology and will always return BarcodeSymbology.MicroQR. Attempting to set this property to any other symbology value is illegal and will result in an ArgumentException being thrown.
