alzabo::create::index
Alzabo::Create::Index(3pm) User Contributed Perl Documentation Alzabo::Create::Index(3pm)NAME
Alzabo::Create::Index - Index objects for schema creation
SYNOPSIS
use Alzabo::Create::Index;
DESCRIPTION
This object represents an index on a table. Indexes consist of columns and optional prefixes for each column. The prefix specifies how
many characters of the columns should be indexes (the first X chars). Some RDBMS's do not have a concept of index prefixes. Not all col-
umn types are likely to allow prefixes though this depends on the RDBMS. The order of the columns is significant.
INHERITS FROM
"Alzabo::Index"
Note: all relevant documentation from the superclass has been merged into this document.
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 ref-
erence 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.
Throws: "Alzabo::Exception::Params", "Alzabo::Exception::RDBMSRules"
table
Returns the "Alzabo::Create::Table" object to which the index belongs.
columns
Returns an ordered list of the "Alzabo::Create::Column" objects that are being indexed.
add_column
Adds a column to the index.
This method takes the following parameters:
* column => "Alzabo::Create::Column" object
* prefix => $prefix (optional)
Throws: "Alzabo::Exception::Params", "Alzabo::Exception::RDBMSRules"
delete_column ("Alzabo::Create::Column" object)
Deletes the given column from the index.
Throws: "Alzabo::Exception::Params", "Alzabo::Exception::RDBMSRules"
prefix ("Alzabo::Create::Column" object)
A column prefix is, to the best of my knowledge, a MySQL specific concept, and as such cannot be set when using an RDBMSRules module for a
different RDBMS. However, it is important enough for MySQL to have the functionality be present. It allows you to specify that the index
should only look at a certain portion of a field (the first N characters). This prefix is required to index any sort of BLOB column in
MySQL.
This method returns the prefix for the column in the index. If there is no prefix for this column in the index, then it returns undef.
set_prefix
This method takes the following parameters:
* column => "Alzabo::Create::Column" object
* prefix => $prefix
Throws: "Alzabo::Exception::Params", "Alzabo::Exception::RDBMSRules"
unique
Returns a boolean value indicating whether the index is a unique index.
set_unique ($boolean)
Sets whether or not the index is a unique index.
fulltext
Returns a boolean value indicating whether the index is a fulltext index.
set_fulltext ($boolean)
Set whether or not the index is a fulltext index.
Throws: "Alzabo::Exception::Params", "Alzabo::Exception::RDBMSRules"
register_column_name_change
This method takes the following parameters:
* column => "Alzabo::Create::Column" object
The column (with the new name already set).
* old_name => $old_name
This method is called by the table object which owns the index when a column name changes. You should never need to call this yourself.
Throws: "Alzabo::Exception::Params"
id
The id is generated from the table, column and prefix information for the index. This is useful as a canonical name for a hash key, for
example.
Returns a string that is the id which uniquely identifies the index in this schema.
