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 );
