Constructor Details

FSTTester

public FSTTester(Random random,
 Directory dir,
 int inputMode,
 List<FSTTester.InputOutput<T>> pairs,
 Outputs<T> outputs)

Method Details

getRandomString

public static String getRandomString(Random random)

[LUCENE-9600] This was made public because a misc module test depends on it. It is not recommended for generic usecase; consider RandomStrings to generate random strings.

simpleRandomString

public static String simpleRandomString(Random r)

toIntsRef

public static IntsRef toIntsRef(String s,
 int inputMode)

toIntsRef

public static IntsRef toIntsRef(String s,
 int inputMode,
 IntsRefBuilder ir)

doTest

public void doTest(boolean testPruning)
            throws IOException

Throws:

IOException

doTest

public FST<T> doTest(int prune1,
 int prune2,
 boolean allowRandomSuffixSharing)
              throws IOException

Throws:

IOException

outputsEqual

protected boolean outputsEqual(T a,
 T b)
