getCount

Returns the number of raw text lines in the unit.

Objective-C
Swift

```
-(NSInteger)getCount;
```
```
func getCount() -> Int
```

Return value

Returns the number of raw text lines in the unit.

getRawTextLine

Swift

-(nullable DSRawTextLine)getRawTextLine:(NSInteger)index;

func getRawTextLine(_ index: Int) -> DSRawTextLine?

Parameters

index: The index of the raw text line.

Return value

Returns a pointer to the RawTextLine object at the specified index.

getRawTextLines

Gets all raw text lines of the unit.

Objective-C
Swift

-(nullable NSArray<DSRawTextLine *> *)getRawTextLines;

func getRawTextLines() -> [DSRawTextLine]?

Return value

Returns all the RawTextLine objects of the unit in an array.

removeAllRawTextLines

Swift

```
-(void)removeAllRawTextLines;
```
```
func removeAllRawTextLines()
```

removeRawTextLine

Removes the raw text line at the specified index.

Objective-C
Swift
