sql::translator::schema::index
SQL::Translator::Schema::Index(3pm) User Contributed Perl Documentation SQL::Translator::Schema::Index(3pm)NAME
SQL::Translator::Schema::Index - SQL::Translator index object
SYNOPSIS
use SQL::Translator::Schema::Index;
my $index = SQL::Translator::Schema::Index->new(
name => 'foo',
fields => [ id ],
type => 'unique',
);
DESCRIPTION
"SQL::Translator::Schema::Index" is the index object.
Primary and unique keys are table constraints, not indices.
METHODS
new
Object constructor.
my $schema = SQL::Translator::Schema::Index->new;
fields
Gets and set the fields the index is on. Accepts a string, list or arrayref; returns an array or array reference. Will unique the field
names and keep them in order by the first occurrence of a field name.
$index->fields('id');
$index->fields('id', 'name');
$index->fields( 'id, name' );
$index->fields( [ 'id', 'name' ] );
$index->fields( qw[ id name ] );
my @fields = $index->fields;
is_valid
Determine whether the index is valid or not.
my $ok = $index->is_valid;
name
Get or set the index's name.
my $name = $index->name('foo');
options
Get or set the index's options (e.g., "using" or "where" for PG). Returns an array or array reference.
my @options = $index->options;
table
Get or set the index's table object.
my $table = $index->table;
type
Get or set the index's type.
my $type = $index->type('unique');
Get or set the index's type.
Currently there are only four acceptable types: UNIQUE, NORMAL, FULL_TEXT, and SPATIAL. The latter two might be MySQL-specific. While both
lowercase and uppercase types are acceptable input, this method returns the type in uppercase.
equals
Determines if this index is the same as another
my $isIdentical = $index1->equals( $index2 );
