LineDataSource (API Reference)

java.lang.Object
- com.here.NativeBase
- - com.here.sdk.mapview.datasource.LineDataSource

extends NativeBase
```
Polyline data source allows the rendering engine access to the user provided polylines geometry and their attributes.
Polyline segments are rendered following the shortest path between their end vertices.
Note: This is a beta release of this feature, so there could be a few bugs and unexpected behavior. Related APIs may change for new releases without a deprecation process.

    Parameters:
    
    line -
    Line to add.
  - add
```
public void add(@NonNull
                java.util.List<LineData> lines)
```
    Adds new lines to the data source.
    
    Parameters:
    
    lines -
    Lines to add.
  - removeAll
```
public void removeAll()
```
    Removes all lines from the data source.
  - forEach
```
public void forEach(@NonNull
                    LineDataSource.LineDataProcessor processor)
```
    Iterates through all the lines from the data source and passes them to the given processor, one by one. The processor can update the line data. The iteration stops after all lines have been processed or the processor returns false from the process call.
    
    Parameters:
    
    processor -
    Line processor.
  - removeIf
```
public void removeIf(@NonNull
                     LineDataSource.LineDataProcessor inspector)
```
    Iterates through all the lines from the data source and passes them to the given inspector, one by one. All lines for which the inspector returns true get removed from the data source. The inspector cannot update the line data.
    
    Parameters:
    
    inspector -
    Line data processor.
  - destroy
```
public void destroy()
```
    Frees all internally used resources. After calling this method, the object is not usable anymore.
