## Attribute Details

### rows

The row count of the QR Code.

```java
public int rows
```

### columns

The column count of the QR Code.

```java
public int columns
```

### errorCorrectionLevel

The error correction level of the QR Code.

```java
public @EnumQRCodeErrorCorrectionLevel int errorCorrectionLevel
```

It is a value of the `EnumQRCodeErrorCorrectionLevel` enumeration.

### version

The version of the QR Code.

```java
public int version
```

### model

Number of models of the QR Code.

```java
public int model
```

### mode

The first data encoding mode of the QR Code.

```java
public int mode
```

### page

The position of the particular symbol in the Structured Append format of the QR Code.

```java
public int page
```

### totalPage

The total number of symbols to be concatenated in the Structured Append format of the QR Code.

```java
public int totalPage
```

### parityData

The Parity Data shall be an 8 bit byte following the Symbol Sequence Indicator. The parity data is a value obtained by XORing byte by byte the ASCII/JIS values of all the original input data before division into symbol blocks.

```java
public byte parityData
```

### dataMaskPattern

The data mask pattern reference for QR Code symbols.

```java
public int dataMaskPattern
```

### codewords

The codewords of the QR Code.

```java
public byte[] codewords
```

## Constructor Details

### QRCodeDetails()

Default constructor. Initializes a new instance of the QRCodeDetails class with default values.

```java
public QRCodeDetails()
```

### QRCodeDetails(int rows, int columns, int errorCorrectionLevel, int version, int model, int mode, int page, int totalPage, int parityData)

Constructor with parameters. Initializes a new instance of the QRCodeDetails class with specified values.

```java
public QRCodeDetails(int rows, int columns, int errorCorrectionLevel, int version, int model, int mode, int page, int totalPage, int parityData)
```
