Method Details

displayHeader

public void displayHeader(int type,
 java.lang.String path,
 java.lang.String copyFromPath,
 long copyFromRevision,
 java.io.OutputStream result)
                   throws SVNException

Description copied from interface: ISVNGNUDiffGenerator

Informs this diff generator about a change to a path.

Specified by:

displayHeader in interface ISVNGNUDiffGenerator

Parameters:

type - one of static fields of this interface

path - a changed path

copyFromPath - a copy-from source path if path is the result of a copy

copyFromRevision - a copy-from source revision if path is the result of a copy

result - an output stream where a header is to be written

Throws:

SVNException

displayFileDiff

public void displayFileDiff(java.lang.String path,
 java.io.File file1,
 java.io.File file2,
 java.lang.String rev1,
 java.lang.String rev2,

 java.lang.String mimeType2,
 java.io.OutputStream result)
                     throws SVNException

Description copied from class: DefaultSVNDiffGenerator

Writes the difference between file1 and file2 as they are seen in rev1 and rev2 to result.

Specified by:

displayFileDiff in interface ISVNDiffGenerator

Overrides:

displayFileDiff in class DefaultSVNDiffGenerator

Parameters:

path - a file path on which the differences are generated and written to the output

file1 - a file with old contents

file2 - a file with new contents
