Datagenerator - dbMonster Data Type

Datagenerator Data Type
String generator
Name : String Generator
Full type name : pl.kernelpanic.dbmonster.generator.StringGenerator
SQL types : char, varchar, text
Description : String generator is used to produce a random string. As a base for generating words it uses an ispell dictionary so the distribution of vowels and consonants is quite similar to english language (although the output text itself is far from that).
Properties
minLength  The minimal length of output string. [default: 0] 
maxLength  The maximul length of output string. The maximum length is limited by the size of Java type of Integer. [default: 255] 
allowSpaces  A boolean value that may be used to cause a StringGenerator not to use any spaces. It is useful for such fields like login or names. [default: true] 
excludeChars  this characters cannot occure in generated string [default: no default value] 
nulls  How many nulls should this generator produce per every 100 generations? [0 - 100, default: 0] 

ex)

<column name="STRINGA" databaseDefault="false">
<generator type="pl.kernelpanic.dbmonster.generator.StringGenerator">
<property name="allowSpaces" value="false"/>
<property name="excludeChars" value=""/>
<property name="maxLength" value="10"/>
<property name="minLength" value="0"/>
<property name="nulls" value="10"/>
</generator>
</column>

nulls  How many nulls should this generator produce per every 100 generations? [0 - 100, default: 0] 

ex)

<column name="TIMESTAMPA" databaseDefault="false">
