DB::Introspector::Util::RelInspect
SYNOPSIS

DESCRIPTION
DB::Introspector::Util::RelInspect is a utility class that contains methods that deal with relationship traversal.
METHODS
- find_paths_between_tables($table_1, $table_2, $option_stop_at_first_contact)
-
Params:
$table_1 - the first element of each path DB::Introspector::Base::Table
$table_2 - the last element of each path DB::Introspector::Base::Table
$option_stop_at_first_contact (1|0) - stop once the destination table ($table_2) has been encountered, rather than continuing to find paths from the destination back to the destination
Returns: (\@) of DB::Introspector::ForeignKeyPath instances. All paths between $parent_table and $child_table.
- find_mapped_paths_between_tables($parent_table, $child_table)
-
Params:
$parent_table - the first element of each path
