LaTeXML::Common::Locator(3pm)

Locator Creation

"$locator = LaTeXML::Common::Locator->new($source, $fromLine, $fromCol, $toLine, $toCol);"

Creates a new locator. $source should be a string containing the full path of the source file, an empty string in case of a literal string, or undef in case of an anonymous string. $fromLine and $fromCol should be integers containing the line and column numbers of the start of the range in the source file, or undef if unknown. $toLine and $toCol should be the integers containing the line and column numbers of the end of the range, or undef if a point is being referred to.

"$locator = LaTeXML::Common::Locator->newRange($from, $to);"

Creates a new locator, starting at the locator $from and ending at the locator $to. Either locator may be undef, in which case the other one is returned.
