Detailed Description

A class to represent and handle ranges of lines. They can be sorted, checked for uniqueness and a line number can be compared to the range (is it before or after?).

getLinesRestrictions()

std::vector< LinesRange > mio::LinesRange::getLinesRestrictions ( const std::string &  args, const std::string &  where, const bool &  negate  )

static

built the set of line ranges to read or skip.

Then each plugin is responsible to call this method if necessary and implement the lines skipping if necessary. Obviously this can not be implemented by every plugin! The line ranges are given as a comma delimited list of either single line numbers or ranges (line numbers delimited by a "-" character). Extra spaces can be given for more clarity in the input.

Parameters

[in]	args	the textual representation of the line ranges or lines to parse
[in]	where	informative string to describe which component it is in case of error messages (ex. "CSV plugin")
[in]	negate	take the negation of the provided ranges (converting a "ONLY" statement into an "EXCLUDE" statement)

Returns

set of line ranges

in()

bool mio::LinesRange::in ( const size_t &  ll ) const

inline

Is the provided line number within the current range?

Parameters

[in]

ll

line number to check

Returns

true if the line number is within the current range, false otherwise

operator<() [1/2]

bool mio::LinesRange::operator< ( const LinesRange &  ll ) const

inline

operator<() [2/2]

bool mio::LinesRange::operator< ( const size_t &  ll ) const

inline

Is the provided line number before the end of the range?

Parameters

[in]

ll

line number to check

Returns

true if the line number is less than the end of the current range, false otherwise

operator==()

bool mio::LinesRange::operator== ( const LinesRange &  ll ) const

inline

operator>()

bool mio::LinesRange::operator> ( const size_t &  ll ) const

inline

Is the provided line number after the start of the range?

Parameters

[in]

ll

line number to check

Returns

true if the line number is greater than the end of the current range, false otherwise

toString()

const std::string mio::LinesRange::toString ( ) const
