Constructor Detail

FileCompare

public FileCompare(int mode,
                   java.lang.String[] ignores,
                   long minDiffTimestamp)

Method Detail

compare

public void compare(FileCompare.Result result,
                    java.lang.String[] sExclude,
                    int recursion)

Compares two directory trees. This method will be called recursively for all sub directories which are found on both sides. Symbolic linked directories (Linux) will be excluded from comparison.

Parameters:

list1 - List for result for dir1

list2 - list for result for dir2

dir1 - A directory

dir2 - The second directory

sExclude - Exclude filter for files (TODO)

compareFile

void compareFile(FileCompare.Result file)

Compare two files.

Parameters:

file -

compareFileContent

boolean compareFileContent(FileCompare.Result result)

Compare two files.

Parameters:

file -

compareFileContent

public static int compareFileContent(java.io.File file1,
                                     java.io.File file2,
                                     java.lang.String endlineComment,
                                     java.lang.String commentStart,
                                     java.lang.String commentEnd,
                                     int[] lineDiff)

Compare two files.

Parameters:

file1 -

file2 -

endlineComment - null or given, then comments and white spaces before are ignored by comparison

commentStart - null or given, then parts with this comments are ignored. Nested comments not allowed.

commentEnd - null or should be given with commentStart

Since:

2023-12-08 to use from outside, 2023-12-08 endlineComment, commentStart, commentEnd does not work yet, TODO

writeDir

boolean writeDir(java.io.PrintStream out,
                 FileCompare.Result entry)

main
