Method Detail

stream

public static <T> Stream<T> stream(int limit,
                                   int length,
                                   Predicate<? super T> filter,
                                   IRandomStringGenerator<T> generator)

generates a limited filtered stream of random strings based on an given generator

Type Parameters:

T - type of strings

Parameters:

limit - number of strings

length - length of each random string

filter - filter method which is applied before the stream is limited

generator - generator

Returns:

limited stream

streamParallel

                                           int length,
                                           IRandomStringGenerator<T> generator)

Type Parameters:

T - type of strings

Parameters:

limit - number of strings

length - length of each random string

generator - generator

Returns:
