Method Detail

getInputStream

public InputStream getInputStream(long seed,
                                  long length,
                                  String... strings)
                           throws IOException

Description copied from interface: RandomTextProvider

Generate a repeatable input stream made up of random words. The stream may be padded with empty space to achieve the required length.

Specified by:

getInputStream in interface RandomTextProvider

Parameters:

seed - - the initial seed for the state of the generator - to give repeatable content

length - - the length of content required in bytes

strings - - an optional array of strings. The first will be in 100% of streams generated, the next 10%, the next 1% etc. Null values will be skipped, so you could add a fixed word to 10% and 0.1% of documents using ...., null, "10", null, ".1")

Throws:

IOException

generateQueryString

public String generateQueryString(long seed,
                                  int words,
                                  int wordLimit)

Description copied from interface: RandomTextProvider

Generate a query string that exactly matches the specific random content in some way

Specified by:

generateQueryString in interface RandomTextProvider

Parameters:

seed - - the initial seed for the state of the generator - to give repeatable content

words - - the number of words required in the query string

wordLimit - - the number of words to consider from the generated stream.

generateQueryString

public String generateQueryString(int words,
                                  double approximateFrequency)

Description copied from interface: RandomTextProvider

Specified by:

generateQueryString in interface RandomTextProvider

Parameters:

words - - the number of words required in the query string

getWordGenerator

public WordGenerator getWordGenerator()

Returns:
