SYNOPSIS

 use DB::Introspector::Util::RelInspect;

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

$child_table - the last element of each path

Returns: (\@) of DB::Introspector::MappedPath instances. All paths between $parent_table and $child_table where $child_table depends on $parent_table, even indirectly.
