loadFromFiles

public void loadFromFiles(com.android.utils.ILogger logger)
                   throws MergingException

Throws:

MergingException - if something goes wrong

loadFile

@Nullable
public F loadFile(@NonNull
                            java.io.File sourceFolder,

Loads a single dataFile from the given source folder (rather than load / parse from all source folders). Like loadFromFiles, all loaded items are set to TOUCHED.

Parameters:

sourceFolder - the source folder

dataFile - the data file within source folder

logger - logs errors

Returns:

a DataFile if successfully loaded, and null otherwise

Throws:
