*Assembly:* DynamsoftBarcodeReader

*Inheritance:* [CBarcodeDetails]({{ site.dbr_cpp_api }}barcode-details.html) -> COneDCodeDetails

```cpp
class COneDCodeDetails : public CBarcodeDetails
```

## Methods

| Method               | Description |
|----------------------|-------------|
| [`COneDCodeDetails`](#conedcodedetails) | Constructor for the COneDCodeDetails class. |
| [`~COneDCodeDetails`](#~conedcodedetails) | Destructor for the COneDCodeDetails class. |

### startCharsBytes

The start chars of the one-dimensional barcode in a byte array.

```cpp
unsigned char* startCharsBytes
```

### startCharsBytesLength

The length of the start chars byte array.

```cpp
int startCharsBytesLength
```

### stopCharsBytes

The stop chars of the one-dimensional barcode in a byte array.

```cpp
unsigned char* stopCharsBytes
```

### stopCharsBytesLength

The length of the stop chars byte array.

```cpp
int stopCharsBytesLength
```

### checkDigitBytes

The check digit chars of the one-dimensional barcode in a byte array.

```cpp
unsigned char* checkDigitBytes
```

### checkDigitBytesLength

The length of the check digit chars byte array.

```cpp
int checkDigitBytesLength
```

### startPatternRange

The position of the start pattern relative to the barcode location.

```cpp
float startPatternRange[2]
```

| Index | Type | Description |
|-------|------|-------------|
| 0     | *float* | X coordinate of the start position in percentage value. |
| 1     | *float* | X coordinate of the end position in percentage value. |

### middlePatternRange

The position of the middle pattern relative to the barcode location.

```cpp
float middlePatternRange[2]
```

| Index | Type | Description |
|-------|------|-------------|
| 0     | *float* | X coordinate of the start position in percentage value. |
| 1     | *float* | X coordinate of the end position in percentage value. |

### endPatternRange

The position of the end pattern relative to the barcode location.

```cpp
float endPatternRange[2]
```

| Index | Type | Description |
|-------|------|-------------|
| 0     | *float* | X coordinate of the start position in percentage value. |
| 1     | *float* | X coordinate of the end position in percentage value. |

### reserved

Reserved memory for the COneDCodeDetails struct. The length of this array indicates the size of the memory reserved for this struct.

```cpp
char reserved[8]
```

### COneDCodeDetails

Constructor for the COneDCodeDetails class.

```cpp
COneDCodeDetails()
```

### ~COneDCodeDetails

Destructor for the COneDCodeDetails class.

```cpp
virtual ~COneDCodeDetails()
```
