Class DiffLinesLabel

java.lang.Object

org.variantsync.diffdetective.variation.DiffLinesLabel

All Implemented Interfaces:

Label

public class DiffLinesLabel
extends Object
implements Label

A label consisting of lines with line number information for each line. Using this label, a VariationDiff encodes all information (except the original line ending encoding, i.e. LF vs CRLF) necessary to reconstruct the original files and, when used during construction, the line diff between these files.

getDiffTrailingLines

public List<DiffLinesLabel.Line> getDiffTrailingLines()

getLines

public List<String> getLines()

Description copied from interface: Label

Returns the lines which need to be printed before the children of a node. Most lines associated with a node should be included in this list, for example, #ifs are stored here.

Specified by:

getLines in interface Label

getTrailingLines

public List<String> getTrailingLines()

Description copied from interface: Label

Returns the lines which need to be printed after the children of a node. For example, #endifs are stored as trailing lines.

Specified by:

getTrailingLines in interface Label

withoutTimeDependentState

public DiffLinesLabel withoutTimeDependentState(Time time)

Returns a deep copy where the line numbers at time are set to DiffLineNumber.InvalidLineNumber.

Specified by:

withoutTimeDependentState in interface Label

See Also:

• Label.withTimeDependentStateFrom(org.variantsync.diffdetective.variation.Label,org.variantsync.diffdetective.variation.diff.Time)

mapWithoutTimeDependentState

private List<DiffLinesLabel.Line> mapWithoutTimeDependentState(List<DiffLinesLabel.Line> lines,
 Time time)

withTimeDependentStateFrom

public DiffLinesLabel withTimeDependentStateFrom(Label otherLabel,
 Time time)

Returns a deep copy where the line numbers at time are copied from otherLabel. The number of lines and their content must be identical in this and otherLabel.

Specified by:

withTimeDependentStateFrom in interface Label

See Also:

• withoutTimeDependentState(org.variantsync.diffdetective.variation.diff.Time)

zipWithTimeDependentStateFrom

private static List<DiffLinesLabel.Line> zipWithTimeDependentStateFrom(List<DiffLinesLabel.Line> linesA,

 Time time)

toString

public String toString()

Overrides:

toString in class Object

clone

public DiffLinesLabel clone()

Description copied from interface: Label

Creates a deep copy of this label.

Specified by:

clone in interface Label

Overrides:

clone in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object
