org.variantsync.diffdetective.variation.diff.serialize.LineGraphImport

public class LineGraphImport
extends Object

Import VariationDiffs from line graph files.

This is a very rudimentary implementation of a deserializer that supports a similar format than LineGraphExport. Rudimentary means that it only deserializes the structure of a variation diff. Most other properties, including the label, line numbers and formulas, are not (always) correctly deserialized. Hence, this is not an inverse of LineGraphExport.

LineGraphImport

public LineGraphImport()

Method Details

fromFile

public static List<VariationDiff<DiffLinesLabel>> fromFile(Path path,
 LineGraphImportOptions<DiffLinesLabel> options)
                                                    throws IOException

Import all VariationDiffs from the given linegraph file.

Parameters:

path - Path to a linegraph file in which only VariationDiffs are stored.

options - Options for the import, such as hints for the used formats for node and edge labels.

Returns:

All VariationDiffs contained in the linegraph file.

Throws:

IOException - when fromLineGraph(BufferedReader, Path, LineGraphImportOptions) throws.

fromLineGraph

public static List<VariationDiff<DiffLinesLabel>> fromLineGraph(BufferedReader lineGraph,
 Path originalFile,
 LineGraphImportOptions<DiffLinesLabel> options)
                                                         throws IOException

Import all VariationDiffs from the given linegraph file.

Parameters:

lineGraph - Reader that reads the linegraph file.

originalFile - Path to the file from which the lineGraph reader is reading.

options - Options for the import, such as hints for the used formats for node and edge labels.

Returns:

All VariationDiffs contained in the linegraph text.

Throws:

IOException

parseVariationDiff

private static VariationDiff<DiffLinesLabel> parseVariationDiff(String lineGraph,
 Path inFile,
 List<DiffNode<DiffLinesLabel>> diffNodeList,
 LineGraphImportOptions<DiffLinesLabel> options)

Generates a VariationDiff from the given, already parsed parameters.

Parameters:

lineGraph - The header line in the linegraph that describes the VariationDiff (starting with t #).

inFile - Path to the linegraph file that is currently parsed.

diffNodeList - All nodes of the VariationDiff that is to be created. The nodes can be assumed to be complete and already connected.

options - LineGraphImportOptions

Returns:

VariationDiff generated from the given, already parsed parameters.
