NAME

       DBIx::DBSchema::ColGroup - Column group objects

SYNOPSIS

	 use DBIx::DBSchema::ColGroup;

	 $colgroup = new DBIx::DBSchema::ColGroup ( $lol_ref );
	 $colgroup = new DBIx::DBSchema::ColGroup ( @lol );
	 $colgroup = new DBIx::DBSchema::ColGroup (
	   [
	     [ 'single_column' ],
	     [ 'multiple_columns', 'another_column', ],
	   ]
	 );

	 $lol_ref = $colgroup->lol_ref;

	 @sql_lists = $colgroup->sql_list;

	 @singles = $colgroup->singles;

DESCRIPTION

       This class is deprecated and included for backwards-compatibility only.	See DBIx::DBSchema::Index for the current class used to store
       unique and non-unique indices.

       DBIx::DBSchema::ColGroup objects represent sets of sets of columns.  (IOW a "list of lists" - see perllol.)

METHODS

       new [ LOL_REF ]
	   Creates a new DBIx::DBSchema::ColGroup object.  Pass a reference to a list of lists of column names.

       lol_ref
	   Returns a reference to a list of lists of column names.

       sql_list
	   Returns a flat list of comma-separated values, for SQL statements.

	   For example:

	     @lol = (
		      [ 'single_column' ],
		      [ 'multiple_columns', 'another_column', ],
		    );

	     $colgroup = new DBIx::DBSchema::ColGroup ( @lol );

	     print join("
", $colgroup->sql_list), "
";

	   Will print:

	     single_column
	     multiple_columns, another_column

       singles
	   Returns a flat list of all single item lists.
