Introduction:

Powerful functions,

Disadvantage: each line of text cannot exceed 1024 characters

 

Differenceengine. difflist_textfile sourcefile NULL;
Differenceengine. difflist_textfile destinationfile = NULL;

Sourcefile = new differenceengine. difflist_textfile ("1.txt ");
Destinationfile = new differenceengine. difflist_textfile ("2.txt ");

Differenceengine. diffengine engine = new differenceengine. diffengine ();
Engine. processdiff (sourcefile, destinationfile, differenceengine. diffenginelevel. fastimperfect );
Arraylist difflines = engine. diffreport ();
Foreach (differenceengine. diffresultspan span in difflines)
{
Switch (span. Status)
{
Case ifferenceengine. diffresultspanstatus. nochange:
// Not changed
Break;
Case differenceengine. diffresultspanstatus. adddestination:
// Newly added
Break;
Case differenceengine. diffresultspanstatus. deletesource:
// Deleted
Break;
Case differenceengine. diffresultspanstatus. replace:
// Modified
Break;
Default:
// Default
Break;

}

}

Example of getting new content:

 

String STR = (differenceengine. textline) (destinationfile. getbyindex (span. destindex). line;
