Method Detail

doDiff

public static DiffModel doDiff(MatchModel match)

Return a diffmodel created using the match model. This implementation is a generic and simple one.

Parameters:

match - The matching model.

Returns:

The corresponding diff model.

doDiff

public static DiffModel doDiff(MatchModel match,
                               boolean threeWay)

Return a diffmodel created using the match model. This implementation is a generic and simple one.

Parameters:

match - the matching model

threeWay - True if we're computing a three way comparison, False otherwise.

Returns:

the corresponding diff model

doDiff

public static DiffResourceSet doDiff(MatchResourceSet matchResourceSet)

Returns a DiffResourceSet created by differencing all MatchModels contained by match. This will call for a two-way differencing.

Parameters:

matchResourceSet - Contains the MatchModels for all compared resources.

Returns:

DiffResourceSet created by differencing all MatchModels.

doDiff

public static DiffResourceSet doDiff(MatchResourceSet matchResourceSet,
                                     boolean threeWay)

Returns a DiffResourceSet created by differencing all MatchModels contained by match. Depending on the value of threeWay, this will call for either two- or three-way differencing.

Parameters:

matchResourceSet - Contains the MatchModels for all compared resources.

threeWay - True if we're computing a three way comparison, False otherwise.

Returns:

DiffResourceSet created by differencing all MatchModels.

getBestDiffEngine

public static IDiffEngine getBestDiffEngine(java.lang.String extension)

Returns the best IDiffEngine for a file given its extension.

Parameters:

extension - The extension of the file we need an IDiffEngine for.

Returns:

The best IDiffEngine for the given file extension.

setDiffEngineSelector

public static void setDiffEngineSelector(IDiffEngineSelector selector)

Sets the diff engine selector that is to be used.

Parameters:

selector - the new engine selector.

getCorrespondingDiffExtensions

public static java.util.Collection<AbstractDiffExtension> getCorrespondingDiffExtensions(java.lang.String extension)

Returns all AbstractDiffExtensions registered against the given file extension.

Parameters:

extension - The extension of the file we need the AbstractDiffExtensions for.

Returns:

All of the AbstractDiffExtensions registered against the given file extension.
