=head1 NAME

Rose::DB::Registry::Entry - Data source registry entry.

=head1 SYNOPSIS

  use Rose::DB::Registry::Entry;

  $entry = Rose::DB::Registry::Entry->new(
    domain   => 'production',
    type     => 'main',
    driver   => 'Pg',
    database => 'big_db',
    host     => 'dbserver.acme.com',
    username => 'dbadmin',
    password => 'prodsecret',
    server_time_zone => 'UTC');

  Rose::DB->register_db($entry);

  # ...or...

  Rose::DB->registry->add_entry($entry);

  ...

=head1 DESCRIPTION

C<Rose::DB::Registry::Entry> objects store information about a single L<Rose::DB> data source.  See the L<Rose::DB> documentation for more information on data sources, and the L<Rose::DB::Registry> documentation to learn how C<Rose::DB::Registry::Entry> objects are managed.

C<Rose::DB::Registry::Entry> inherits from, and follows the conventions of, L<Rose::Object>.  See the L<Rose::Object> documentation for more information.

=head1 CONSTRUCTOR

=over 4

=item B<new PARAMS>

Constructs a C<Rose::DB::Registry::Entry> object based on PARAMS, where PARAMS are name/value pairs.  Any object method is a valid parameter name.

=back

=head1 OBJECT METHODS

=head2 GENERAL

=over 4

=item B<autocommit [VALUE]>

Get or set the value of the "AutoCommit" connect option.

=item B<catalog [CATALOG]>

Get or set the database catalog name.  This setting is only relevant to databases that support the concept of catalogs.

=item B<clone>

Returns a clone (i.e., deep copy) of the current object.

=item B<connect_option NAME [, VALUE]>

Get or set the connect option named NAME.  Returns the current value of the connect option.

=item B<connect_options [HASHREF | PAIRS]>

Get or set the options passed in a hash reference as the fourth argument to the call to C<DBI-E<gt>connect()>.  See the C<DBI> documentation for descriptions of the various options.

If a reference to a hash is passed, it replaces the connect options hash.  If a series of name/value pairs are passed, they are added to the connect options hash.

Returns a reference to the hash of options in scalar context, or a list of name/value pairs in list context.

=item B<database [NAME]>

Get or set the database name.

=item B<description [TEXT]>

A description of the data source.

=item B<domain [DOMAIN]>

Get or set the data source domain.  Note that changing the C<domain> after a registry entry has been added to the registry has no affect on where the entry appears in the registry.

=item B<driver [DRIVER]>

Get or set the driver name.  The DRIVER argument is converted to lowercase before being set.

=item B<dsn [DSN]>

Get or set the C<DBI> DSN (Data Source Name).  Note that an explicitly set DSN may render some other attributes inaccurate.  For example, the DSN may contain a host name that is different than the object's current C<host()> value.  I recommend not setting the DSN value explicitly unless you are also willing to manually synchronize (or ignore) the corresponding object attributes.

=item B<dump>

Returns a reference to a hash of the entry's attributes.  Only those attributes with defined values are included in the hash keys.  All values are deep copies.

=item B<handle_error [VALUE]>

Get or set the value of the "HandleError" connect option.

=item B<host [NAME]>

Get or set the database server host name.

=item B<password [PASS]>

Get or set the database password.

=item B<port [NUM]>

Get or set the database server port number.

=item B<pre_disconnect_sql [STATEMENTS]>

Get or set the SQL statements that will be run immediately before disconnecting from the database.  STATEMENTS should be a list or reference to an array of SQL statements.  Returns a reference to the array of SQL statements in scalar context, or a list of SQL statements in list context.

=item B<post_connect_sql [STATEMENTS]>

Get or set the SQL statements that will be run immediately after connecting to the database.  STATEMENTS should be a list or reference to an array of SQL statements.  Returns a reference to the array of SQL statements in scalar context, or a list of SQL statements in list context.

=item B<print_error [VALUE]>

Get or set the value of the "PrintError" connect option.

=item B<raise_error [VALUE]>

Get or set the value of the "RaiseError" connect option.

=item B<schema [SCHEMA]>

Get or set the database schema name.  This setting is only useful to databases that support the concept of schemas (e.g., PostgreSQL).

=item B<server_time_zone [TZ]>

Get or set the time zone used by the database server software.  TZ should be a time zone name that is understood by C<DateTime::TimeZone>.  See the C<DateTime::TimeZone> documentation for acceptable values of TZ.

=item B<type [TYPE]>

Get or set the  data source type.  Note that changing the C<type> after a registry entry has been added to the registry has no affect on where the entry appears in the registry.

=item B<username [NAME]>

Get or set the database username.

=back

=head2 DRIVER-SPECIFIC ATTRIBUTES

=head3 MySQL

These attributes should only be used with registry entries where the L<driver|/driver> is C<mysql>.

Get or set the L<mysql_use_result|DBD::mysql/mysql_use_result> database handle attribute.  This is set directly on the L<dbh|Rose::DB/dbh>, if one exists.  Otherwise, it will be set when the L<dbh|Rose::DB/dbh> is created.  If no value for this attribute is defined (the default) then it will not be set when the L<dbh|Rose::DB/dbh> is created, deferring instead to whatever default value L<DBD::mysql> chooses.

Returns the value of this attribute in the L<dbh|Rose::DB/dbh>, if one exists, or the value that will be set when the L<dbh|Rose::DB/dbh> is next created.

See the L<DBD::mysql|DBD::mysql/mysql_use_result> documentation to learn more about this attribute.

=item B<european_dates [BOOL]>

Get or set the boolean value that determines whether or not dates are assumed to be in european dd/mm/yyyy format.  The default is to assume US mm/dd/yyyy format (because this is the default for PostgreSQL).

This value will be passed to L<DateTime::Format::Pg> as the value of the C<european> parameter in the call to the constructor C<new()>.  This L<DateTime::Format::Pg> object is used by L<Rose::DB::Pg> to parse and format date-related column values in methods like L<parse_date|Rose::DB/parse_date>, L<format_date|Rose::DB/format_date>, etc.

=item B<pg_enable_utf8 [BOOL]>

Get or set the L<pg_enable_utf8|DBD::Pg/pg_enable_utf8> database handle attribute.  This is set directly on the L<dbh|Rose::DB/dbh>, if one exists.  Otherwise, it will be set when the L<dbh|Rose::DB/dbh> is created.  If no value for this attribute is defined (the default) then it will not be set when the L<dbh|Rose::DB/dbh> is created, deferring instead to whatever default value L<DBD::Pg> chooses.

Returns the value of this attribute in the L<dbh|Rose::DB/dbh>, if one exists, or the value that will be set when the L<dbh|Rose::DB/dbh> is next created.

See the L<DBD::Pg|DBD::Pg/pg_enable_utf8> documentation to learn more about this attribute.

=item B<sslmode [MODE]>

Get or set the SSL mode of the connection.  Valid values for MODE are C<disable>, C<allow>, C<prefer>, and C<require>.  See the L<DBD::Pg|DBD::Pg/connect> documentation to learn more about this attribute.

=head3 SQLite

These attributes should only be used with registry entries where the L<driver|/driver> is C<sqlite>.

=over 4

=item B<auto_create [BOOL]>

Get or set a boolean value indicating whether or not a new SQLite L<database|Rose::DB/database> should be created if it does not already exist.  Defaults to true.

If false, and if the specified L<database|Rose::DB/database> does not exist, then a fatal error will occur when an attempt is made to L<connect|Rose::DB/connect> to the database.
