DSDecodedBarcodesUnit Class

The DSDecodedBarcodesUnit class represents a unit that contains decoded barcode elements. It inherits from the [DSIntermediateResultUnit]({{ site.dcv_ios_api }}core/intermediate-results/intermediate-result-unit.html) class.

Definition

Assembly: DynamsoftBarcodeReader.framework

>- Objective-C >- Swift > >1. ```objc NS_SWIFT_NAME(DecodedBarcodesUnit) @interface DSDecodedBarcodesUnit: DSIntermediateResultUnit ``` 2. ```swift class DecodedBarcodesUnit: DSIntermediateResultUnit ```

Methods

Method	Description
getDecodedBarcodes	Get all the barcodes that are decoded from the image.
getCount	Get the number of decoded barcodes.
getDecodedBarcode	Get the decoded barcode by specifying the index.
removeAllDecodedBarcodes	Remove all the decoded barcodes.
setDecodedBarcode	Set the decoded barcode.

Inherited Methods

The following methods are inherited from class [DSIntermediateResultUnit]({{ site.dcv_ios_api }}core/intermediate-results/intermediate-result-unit.html).

getDecodedBarcodes

Get all the barcodes that are decoded from the image.

>- Objective-C >- Swift > >1. ```objc - (nullable NSArray*)getDecodedBarcodes ``` 2. ```swift func getDecodedBarcodes() -> [DSDecodedBarcodeElement]? ```

Return Value

An array of DSDecodedBarcodeElement as the decoded barcodes.

getCount

Get the number of decoded barcodes.

>- Objective-C >- Swift > >1. ```objc - (NSInteger)getCount ``` 2. ```swift func getCount() -> NSInteger ```

Return Value

The number of decoded barcodes.

getDecodedBarcode

Get the DSDecodedBarcodeElement object at the specified index.

>- Objective-C >- Swift > >1. ```objc - (nullable DSDecodedBarcodeElement*)getDecodedBarcode:(NSInteger)index ``` 2. ```swift func getDecodedBarcode(index: NSInteger) -> DSDecodedBarcodeElement? ```

Parameters

[in] index: The index of the decoded barcode.

Return Value

A DSDecodedBarcodeElement object as the decoded barcode object at the specified index.

removeAllDecodedBarcodes

Remove all the DSDecodedBarcodeElement of the unit.

>- Objective-C >- Swift > >1. ```objc - (void)removeAllDecodedBarcodes ``` 2. ```swift func removeAllDecodedBarcodes() ```

setDecodedBarcode

Set the DSDecodedBarcodeElement object.

>- Objective-C >- Swift > >1. ```objc - (NSInteger)setDecodedBarcode:(DSDecodedBarcodeElement*)element matrixToOriginalImage:(CGAffineTransform)matrixToOriginalImage ``` 2. ```swift func setDecodedBarcode(element: DSDecodedBarcodeElement, matrixToOriginalImage: CGAffineTransform) -> Int ```

Parameters

[in] element: The decoded barcode object to be set.

[in] matrixToOriginalImage: The matrix to convert the decoded barcode object to the original image.

Return Value

Returns the ErrorCode if failed. Otherwise, returns 0.
