java.lang.Object | +--JLibDiff.diff
The diff
class compares two files. it compares also two
BufferedReaders or two strings.
after the comparison the vector will represents a list of hunk
corresponding with blocks of difference.
to generate a file of difference, one can instanciate as follows the class diff:
diff d = new diff(file1,file2);
which is equivalent to:
diff d = new diff(); d.diffFile(file1,file2);
To compare two BufferedReaders or two String we have to instanciate as follows:
diff d = new diff(); d.diffBuffer(BufferedReader1,BufferedReader2);
or:
diff d = new diff(); d.diffString(String1,String2);
The class diff
includes methods for examining, printing
or saveing blocks of difference: (Hunks).
Here are some more examples of how diff
can be used:
diff d=new diff(args[0],args[1]); d.print(); d.save("diff.txt");
Example using BufferedReader and ED_format:
BufferedReader in=new BufferedReader(new FileReader(args[0])); BufferedReader inn=new BufferedReader(new FileReader(args[1])); diff d = new diff(); d.diffBuffer(in,inn); d.print_ED(); d.save_ED("diff.txt");
To go throw the list of Hunks we can choose between an Enumeration or a loop by spesifyng index in the vector to get at each time the corresponding Hunk.
Vector v=d.getHunk(); for(Enumeration e=v.element();e.hasMoreElements(); ) { System.out.print(((Hunk)e.nextElement()).convert()); }
or:
diff d = new diff(file1,file2); for(int i=0; i
