/**
i_rPageRange: the string to be changed into a sequence of numbers
valid format example "5-3,9,9,7-8" ; instead of ',' ';' or ' ' are allowed as well
o_rPageVector: the output sequence of numbers
i_nLogicalOffset: an offset to be applied to each number in the string before inserting it in the resulting sequence
example: a user enters page numbers from 1 to n (since that is logical)
of course usable page numbers in code would start from 0 and end at n-1
so the logical offset would be -1
i_nMinNumber: the minimum allowed number
i_nMaxNumber: the maximum allowed number
@returns: true if the input string was valid, o_rPageVector will contain the resulting sequence
false if the input string was invalid, o_rPageVector will contain
the sequence that parser is able to extract
behavior:
- only non-negative sequence numbers are allowed
- only non-negative values in the input string are allowed
- the string "-3" means the sequence i_nMinNumber to 3
- the string "3-" means the sequence 3 to i_nMaxNumber
- the string "-" means the sequence i_nMinNumber to i_nMaxNumber
- single number that doesn't fit in [i_nMinNumber,i_nMaxNumber] will be ignored
- range that doesn't fit in [i_nMinNumber,i_nMaxNumber] will be adjusted
