## Method Detail

### init

Default constructor of a `CodeParser` object.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
- (instancetype)init;
```
2. 
```swift
init()
```

### InitSettingsFromFile

Initialize settings from a given file.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
- (BOOL)initSettingsFromFile:(NSString *)filePath
                       error:(NSError * _Nullable * _Nullable)error;
```
2. 
```swift
func initSettingsFromFile(_ filePath:String) throws -> BOOL
```

**Parameters**

`filePath`: The path of the settings file.

### InitSettings

Initialize settings from a given string.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
- (BOOL)initSettings:(NSString *)content
               error:(NSError * _Nullable * _Nullable)error;
```
2. 
```swift
func initSettings(_ content:String) throws -> BOOL
```

**Parameters**

`content`: A JSON string that represents the content of the settings.

### Parse

Parses code data for human-readable results.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
- (nullable DSParsedResultItem *)parse:(NSData *)bytes
                       taskSettingName:(NSString *)taskSettingName
                                 error:(NSError * _Nullable * _Nullable)error;
```
2. 
```swift
func parse(_ bytes:Data, taskSettingName:String) throws -> ParsedResultItem
```

**Parameters**

`bytes` The array of bytes which contain the code string.

`taskSettingName`<sub>Optional</sub> The name of [`CodeParserTaskSetting`](/capture-vision/docs/core/parameters/file/task-settings/code-parser-task-settings.html) which defines the settings used for code parsing.

**Return Value**

Returns [`ParsedResultItem`](/code-parser/docs/mobile/programming/ios/api-reference/parsed-result-item.html) which stores the human-readable results.

### ResetSettings

Reset all parameters to default values.
