NAME

Data::Transform::Value - a transformer that filters by node value

DESCRIPTION

Data::Transform::Value is a transformer that applies to one or more node values. It can either match exactly if the node value and the supplied value are equal, or it can match loosely if the supplied value is a compiled regular expression, or a callback CODEREF.

FIELDS

value (required param)

value is required and can either be a simple scalar value, or a CODE reference, or a compiled regular expression.

METHODS

applies_to( %params )

Requires $params{value} to exist

Returns $MATCH_EXACT_VALUE if neither $params{value} nor value are defined, or if $params{value} is not a reference and $params{value} equals value.

Returns $MATCH_LIKE_VALUE if value is a regular expression and it matches $params{value} or if value is a CODE reference and returns a truth-y value when given $params{value}.

Returns $NO_MATCH otherwise.
