NAME

Alzabo::Create::Index - Index objects for schema creation

SYNOPSIS

  use Alzabo::Create::Index;

INHERITS FROM

Alzabo::Index

METHODS

new

The constructor takes the following parameters:

• table => Alzabo::Create::Table object

  The table that this index is indexing.

• columns => [ Alzabo::Create::Column object, .. ]

• columns => [ { column => Alzabo::Create::Column object, prefix => $prefix }, repeat as needed ... ]

  This parameter indicates which columns that are being indexed. It can either be an array reference of column objects, or an array reference of hash references, each with a key called column and one called prefix.

  The prefix key is optional.

• unique => $boolean

  Indicates whether or not this is a unique index.

• fulltext => $boolean

  Indicates whether or not this is a fulltext index.

• function => $string

  This can be used to create a function index where supported. The value of this parameter should be the full function, with column names, such as LCASE( username ).

  The "columns" parameter should include all the columns used in the function.

Returns a new Alzabo::Create::Index object.
