Constructor & Destructor Documentation

◆ LinePartIterator()

ROOT::option::PrintUsageImplementation::LinePartIterator::LinePartIterator ( const Descriptor usage[] )

inline

Creates an iterator for usage.

Definition at line 1982 of file OptionParser.h.

Member Function Documentation

◆ column()

int ROOT::option::PrintUsageImplementation::LinePartIterator::column ( )

inline

Returns the index (counting from 0) of the column in which the part pointed to by data() is located.

Definition at line 2148 of file OptionParser.h.

◆ data()

const char * ROOT::option::PrintUsageImplementation::LinePartIterator::data ( )

inline

Returns the current part of the iteration.

Definition at line 2182 of file OptionParser.h.

◆ length()

int ROOT::option::PrintUsageImplementation::LinePartIterator::length ( )

inline

Returns the length of the part pointed to by data() in raw chars (not UTF-8 characters).

Definition at line 2165 of file OptionParser.h.

◆ line()

int ROOT::option::PrintUsageImplementation::LinePartIterator::line ( )

inline

Returns the index (counting from 0) of the line within the current column this part belongs to.

Definition at line 2157 of file OptionParser.h.

◆ next()

bool ROOT::option::PrintUsageImplementation::LinePartIterator::next ( )

inline

Moves iteration to the next part (if any).

Has to be called once after each call to nextRow() to move to the 1st part of the row.

Return values

false if moving to next part failed because no further part exists.

See LinePartIterator for details about the iteration.

Definition at line 2076 of file OptionParser.h.

◆ nextRow()

bool ROOT::option::PrintUsageImplementation::LinePartIterator::nextRow ( )

inline

Moves iteration to the next row (if any).

Has to be called once after each call to nextTable() to move to the 1st row of the table.

Return values

false if moving to next row failed because no further row exists.

Definition at line 2026 of file OptionParser.h.

◆ nextTable()

bool ROOT::option::PrintUsageImplementation::LinePartIterator::nextTable ( )

inline

Moves iteration to the next table (if any).

Has to be called once on a new LinePartIterator to move to the 1st table.

Return values

false if moving to next table failed because no further table exists.

Definition at line 1993 of file OptionParser.h.
