NAME
       DBIx::Class::Schema::Loader::RelBuilder - Builds relationships for DBIx::Class::Schema::Loader

SYNOPSIS
       See DBIx::Class::Schema::Loader and DBIx::Class::Schema::Loader::Base.

DESCRIPTION
       This class builds relationships for DBIx::Class::Schema::Loader.  This is module is not (yet) for external use.

METHODS
   new
       Arguments: $loader object

   generate_code
       Arguments:

	   [
	       [ local_moniker1 (scalar), fk_info1 (arrayref), uniq_info1 (arrayref) ]
	       [ local_moniker2 (scalar), fk_info2 (arrayref), uniq_info2 (arrayref) ]
	       ...
	   ]

       This generates the code for the relationships of each table.

       "local_moniker" is the moniker name of the table which had the REFERENCES statements.  The fk_info arrayref's contents should take the
       form:

	   [
	       {
		   local_table	  => 'some_table',
		   local_moniker  => 'SomeTable',
		   local_columns  => [ 'col2', 'col3' ],
		   remote_table   => 'another_table_moniker',
		   remote_moniker => 'AnotherTableMoniker',
		   remote_columns => [ 'col5', 'col7' ],
	       },
	       {
		   local_table	  => 'some_other_table',
		   local_moniker  => 'SomeOtherTable',
		   local_columns  => [ 'col1', 'col4' ],
		   remote_table   => 'yet_another_table_moniker',
		   remote_moniker => 'YetAnotherTableMoniker',
		   remote_columns => [ 'col1', 'col2' ],
	       },
	       # ...
	   ],

       The uniq_info arrayref's contents should take the form:

	   [
	       [
		   uniq_constraint_name 	=> [ 'col1', 'col2' ],
	       ],
	       [
		   another_uniq_constraint_name => [ 'col1', 'col2' ],
	       ],
	   ],

       This method will return the generated relationships as a hashref keyed on the class names.  The values are arrayrefs of hashes containing
       method name and arguments, like so:

	 {
	     'Some::Source::Class' => [
		 { method => 'belongs_to', arguments => [ 'col1', 'Another::Source::Class' ],
		 { method => 'has_many', arguments => [ 'anothers', 'Yet::Another::Source::Class', 'col15' ],
	     ],
	     'Another::Source::Class' => [
		 # ...
	     ],
	     # ...
	 }
