NAME
Sort::Key::DateTime - Perl extension for sorting objects by some DateTime keySYNOPSIS
use Sort::Key::DateTime qw(dtkeysort);
my @sorted = dtkeysort { $_->date } @meetings;
DESCRIPTION
Sort::Key::DateTime allows to sort objects by some (calculated) key of type DateTime.EXPORTS
- dtkeysort { CALC_DT_KEY } @array
- returns the elements on @array sorted by the
DateTime key calculated applying "{ CALC_DT_KEY
}" to them.
Inside "{ CALC_DT_KEY }", the object is available as $_.
NOTE: sorting order is undefined when floating and non floating DateTime keys are mixed.
- rdtkeysort { CALC_DT_KEY } @array
- sorted @array in descending order
- dtsort(@array)
- rdtsort(@array)
- sort an array of DateTime objects in ascending and descending order
respectively.
Example:
my @sorted = dtsort @unsorted; - dtkeysort_inplace { CALC_DT_KEY } @array
- rdtkeysort_inplace { CALC_DT_KEY } @array
- dtsort @array
- rdtsort @array
- sort @array in place.
- mkkey_datetime($dt)
- generates string sorting keys for DateTime objects
