Data::TreeValidator::Leaf - Represents a single leaf node in the validation tree specification
Represents a leaf in a tree, that is - a single atomic value. At some point all branches will reduce to these nodes.
Returns an array of all constraints for this leaf.
Adds a constraint to this leaf, at the end of the list
Returns an array of all transformations for this leaf.
Adds a transformation for this leaf, at the end of the list
Takes $input,
and matches it against all the constraints for this leaf.
If they all pass (that is,
none throw exceptions),
then $input is passed through all leaf transformations.
AT the end of processing, a Data::TreeValidator::Result::Leaf object is returned. This can be inspected to determine if validation was sucessful, and obtain clean data.
