Re: [Geotools-gt2-users] Simple map with points

OK, actually, the method that has a metadata parameter is
AttributeTypeFactory.newInstance().

public static AttributeType newAttributeType(String name,
                                             Class clazz,
                                             boolean isNillable,
                                             int fieldLength,
                                             Object defaultValue)
ok, so I can put true to isNillable, but what does fieldLenght mean ?

and my previous question is still valid :
