Constructor Detail

StreamComparator

public StreamComparator(java.io.BufferedInputStream stream1,
                        java.io.BufferedInputStream stream2,
                        boolean useResultsStarter1,
                        boolean useResultsStarter2)

Method Detail

compareStreams

public void compareStreams()

Metoda porovna obsah obou streamu a vraci, zda se rovnaji

skipAllNextWhitespaces

private static void skipAllNextWhitespaces(java.io.BufferedInputStream s)
                                    throws java.io.IOException

Metoda preskoci vsechny bile znaky ve stremu od act. pozice az k prvnimu nebilemu

Parameters:

s -

Throws:

java.io.IOException

containsOnlyWhitespaces

public static boolean containsOnlyWhitespaces(java.lang.String s)

Vraci, zda retezec obsahuje pouze bile znaky

Parameters:

s -

Returns:

isWhiteChar

public static boolean isWhiteChar(char c)

readNextNonWhiteChar

private int readNextNonWhiteChar(java.io.InputStream s,
                                 int index)
                          throws java.io.IOException

Throws:

java.io.IOException

readNextLine

private static java.lang.String readNextLine(java.io.BufferedInputStream in)
                                      throws java.io.IOException

Throws:

java.io.IOException

trimRight

public static java.lang.String trimRight(java.lang.String s)

alternateCompareAtPos

public static boolean alternateCompareAtPos(java.lang.String s1,
                                            java.lang.String s2,
                                            int pos)

nastala tato situace: Dva vstupni radky porovnavanych streamu (s1,s2) se na pozici "pos" prestaly rovnat. Je jeste ale sance, ze by porovnavani melo dopadnout dobre - treba jsou tu dva floaty, ktere se jen lisi presnosti... Proto tahle metoda vraci, jestli jsou radky opravdu ruzne (false) nebo jestli i pres tenhle rozdil maji byt vyhodnoceny jako stejne (true).

Pozor - tyhle tokeny uz museji byt na konci radky!

Tahle metod extrahuje dva "tokeny" z tech radek - tj. to "slovo", "cislo" ci cokoliv oddelene jakymikoliv znaky jinymi nez cislo, pismeno, tecka a carka a vola metodu alternateCompareTokens()

getMyTokenFromStr

private static java.lang.String getMyTokenFromStr(java.lang.String s,
                                                  int pos)

Pomocna pro alternateCompareAtPos()

alternateCompareTokens

public static boolean alternateCompareTokens(java.lang.String token1,
                                             java.lang.String token2)

areSimilarDoubles

public static boolean areSimilarDoubles(java.lang.String token1,
                                        java.lang.String token2)

scrollAfterResultsStarter

private java.lang.String scrollAfterResultsStarter(java.io.BufferedInputStream s,
                                                   int streamIndex)

Metoda jede vstupnim streamem az do okamziku, kdy nacte presne retezec definovany v Constants.RESULTS_STARTER nebo na konec streamu

Parameters:

s - Vstupni stream

getStream1

public java.io.BufferedInputStream getStream1()
