NAME

       Badger::Data::Facet::Text::Whitespace - validation facet for whitespace

DESCRIPTION

       This module implements a validation facets for munging whitespace on text values.

METHODS

       This module implement the following methods in addition to those inherited from the
       Badger::Data::Facet::Text, Badger::Data::Facet and Badger::Base base classes.

   validate($text_ref, $type)
       This method performs whitespace handling on the text passed by reference as the first
       argument.

       If the pre-defined "action" is "preserve" then the text will be unmodified.

       If the "action" is "fold" then all whitespace characters in the text (carriage returns,
       newlines, tabs) will be converted to spaces.

       If the "action" is "collapse" then all whitespace characters will first be converted to
       spaces as per "fold".  Any leading and trailing whitespace is then removed and any
       sequences of multiple spaces are collapsed to a single space.
