Detailed Description

Synopsis

use Bio::EnsEMBL::Registry;
 
my $registry = 'Bio::EnsEMBL::Registry';
 
$registry->load_all("configuration_file");
 
$gene_adaptor = $registry->get_adaptor( 'Human', 'Core', 'Gene' );

Description

All Adaptors are stored/registered using this module. This module should
then be used to get the adaptors needed.

The registry can be loaded from a configuration file using the load_all
method.

If a filename is passed to load_all then this is used.  Else if the
environment variable ENSEMBL_REGISTRY is set to the name on an existing
configuration file, then this is used.  Else if the file .ensembl_init
in your home directory exist, it is used.

For the Web server ENSEMBL_REGISTRY should be set in SiteDefs.pm.  This
will then be passed on to load_all.


The registry can also be loaded via the method load_registry_from_db
which given a database host will load the latest versions of the Ensembl
databases from it.

The four types of registries are for db adaptors, dba adaptors, dna
adaptors and the standard type.

db


These are registries for backwards compatibility and enable the
subroutines to add other adaptors to connections.

e.g. get_all_db_adaptors, get_db_adaptor, add_db_adaptor,
remove_db_adaptor are the old DBAdaptor subroutines which are now
redirected to the Registry.

So if before we had

  my $sfa = $self->adaptor()->db()->get_db_adaptor('blast');

We now want to change this to

  my $sfa =
    Bio::EnsEMBL::Registry->get_adaptor( "human", "core", "blast" );

DBA


These are the stores for the DBAdaptors

The Registry will create all the DBConnections needed now if you set up
the configuration correctly. So instead of the old commands like

  my $db           = Bio::EnsEMBL::DBSQL::DBAdaptor->new(...);
  my $exon_adaptor = $db->get_ExonAdaptor;

we should now have just

  my $exon_adaptor =
    Bio::EnsEMBL::Registry->get_adaptor( "human", "core", "exon" );

DNA


This is an internal Registry and allows the configuration of a dnadb.
An example here is to set the est database to get its dna data from the
core database.

  ## set the est db to use the core for getting dna data.
  # Bio::EnsEMBL::Utils::ConfigRegistry->dnadb_add( "Homo Sapiens",
  #   "core", "Homo Sapiens", "est" );

adaptors


This is the registry for all the general types of adaptors like
GeneAdaptor, ExonAdaptor, Slice Adaptor etc.

These are accessed by the get_adaptor subroutine i.e.

  my $exon_adaptor =
    Bio::EnsEMBL::Registry->get_adaptor( "human", "core", "exon" );

                  set of aliases.  This can work across any adaptor
                  which has a MetaContainer.  If no MetaContainer
                  can be returned from a given adaptor then no alias
                  searching is performed.

  Return type   : none

◆ load_all()

public Int Bio::EnsEMBL::Registry::load_all ( )

 Will load the registry with the configuration file which is
 obtained from the first in the following and in that order.

  1) If an argument is passed to this method, this is used as the
     name of the configuration file to read.

  2) If the environment variable ENSEMBL_REGISTRY is set, this is
     used as the name of the configuration file to read.

  3) If the file .ensembl_init exist in the home directory, it is
     used as the configuration file.

  Arg [1]    : (optional) string
               Name of file to load the registry from.

  Arg [2]    : (optional) integer
               If not 0, will print out all information.

  Arg [3]    : (optional) integer
               If not 0, the database connection will not be
               cleared, if 0 or if not set the database connections
               will be cleared (this is the default).

  Arg [4]:     (optional) boolean
               This option will turn off caching for slice features,
               so, every time a set of features is retrieved,
               they will come from the database instead of the
               cache.  This option is only recommended for advanced
               users, specially if you need to store and retrieve
               features.  It might reduce performance when querying
               the database if not used properly.  If in doubt, do
               not use it or ask in the developer mailing list.

  Arg [5]:     (optional) boolean
               This option will make load_all() throw if the configuration file
               is missing and cannot be guessed from the environment

  Example    :

Bio::EnsEMBL::Registry->load_all();

  Returntype : Int count of the DBAdaptor instances which can be found in the 
               registry due to this method being called. Will never be negative
  Exceptions : Throws if $throw_if_missing is set and ($config_file is missing

◆ load_registry_from_db()

public Int Bio::EnsEMBL::Registry::load_registry_from_db ( )

  Arg [HOST] : string
                The domain name of the database host to connect to.

  Arg [USER] : string
                The name of the database user to connect with.

  Arg [PASS] : (optional) string
                The password to be used to connect to the database.

  Arg [PORT] : (optional) integer
                The port to use when connecting to the database.

  Arg [VERBOSE]: (optional) boolean
                Whether to print database messages. This includes a listing
                of all available species & databases.

  Arg [SPECIES]: (optional) string
                By default, all databases that are found on the
                server and that corresponds to the correct release
                are probed for aliases etc.  For some people,
                depending on where they are in the world, this might
                be a slow operation.  With the '-species' argument,
                one may reduce the startup time by restricting the
                set of databases that are probed to those of a
                particular species.

                Note that the latin name of the species is required,
                e.g., 'homo sapiens', 'gallus gallus', 'callithrix
                jacchus' etc.  It may be the whole species name,
                or only the first part of the name, e.g. 'homo',
                'gallus', or 'callithrix'.  This will be used in
                matching against the name of the databases.

  Arg [DB_VERSION]: (optional) integer
                By default, only databases corresponding to the
                current API version are loaded.  This argument
                allows the script to use databases from another
                version although it might not work properly.  This
                argument should only be used for production or
                testing purposes and if you really know what you are
                doing.

  Arg [WAIT_TIMEOUT]: (optional) integer
                Time in seconds for the wait timeout to happen.
                Time after which the connection is deleted if not
                used.  By default this is 28800 (8 hours), so set
                this to greater than this if your connection are
                getting deleted.  Only set this if you are having
                problems and know what you are doing.

   Arg [-NO_CACHE]: (optional) boolean
                This option will turn off caching for slice features,
                so, every time a set of features is retrieved, they
                will come from the database instead of the cache.  This
                option is only recommended for advanced users, specially
                if you need to store and retrieve features.  It might
                reduce performance when querying the database if not
                used properly.  If in doubt, do not use it or ask in the
                developer mailing list.

   Arg [SPECIES_SUFFIX]: (optional) string
                This option will append the string to the species name
                in the registry for all databases found on this server.

  Example :

$registry->load_registry_from_db(
  -host    => 'ensembldb.ensembl.org',
  -user    => 'anonymous',
  -verbose => '1'
);

  Description: Will load the correct versions of the Ensembl
               databases for the software release it can find on a
               database instance into the registry.  Also adds a set
               of standard aliases.

  Returntype : Int count of the DBAdaptor instances which can be found in the 
               registry due to this method call.

  Exceptions : Thrown if the given MySQL database cannot be connected to
               or there is any error whilst querying the database.
  Status     : Stable

◆ load_registry_from_multiple_dbs()

public Int Bio::EnsEMBL::Registry::load_registry_from_multiple_dbs ( )

  Arg [1]   : Array of hashes, each hash being a set of arguments to
              load_registry_from_db() (see above).

  Example   :

$registry->load_registry_from_multiple_dbs( {
    '-host'    => 'ensembldb.ensembl.org',
    '-user'    => 'anonymous',
    '-verbose' => '1'
  },
  {
    '-host'     => 'server.example.com',
    '-user'     => 'anonymouse',
    '-password' => 'cheese',
    '-verbose'  => '1'
  } );

  Description:  Will call load_registry_from_db() (see above)
                multiple times and merge the resulting registries
                into one, effectively allowing a user to connect to
                databases on multiple database servers from within
                one program.

                If a database is found on more than one server, the
                first found instance of that database will be used.

  Returntype : Int count of the DBAdaptor instances which can be found in the 
               registry

◆ load_registry_from_url()

public Int Bio::EnsEMBL::Registry::load_registry_from_url ( )

  Arg [1] : string $url
  Arg [2] : (optional) integer
            If not 0, will print out all information.
  Arg [3] : (optional) integer
          This option will turn off caching for slice features, so,
          every time a set of features is retrieved, they will come
          from the database instead of the cache. This option is only
          recommended for advanced users, specially if you need to
          store and retrieve features. It might reduce performance when
          querying the database if not used properly. If in doubt, do
          not use it or ask in the developer mailing list.

  Example :

load_registry_from_url(

  Description: Will load the correct versions of the ensembl
               databases for the software release it can find on
               a database instance into the registry. Also adds
               a set of standard aliases. The url format is:
               mysql://[[username][:password]@]hostname[:port].  You
               can also request a specific version for the databases
               by adding a slash and the version number but your
               script may crash as the API version won't match the
               DB version.

               You can also specify a database name which will cause the 
               loading of a single DBAdaptor instance. Parameters are
               mapped from a normal URL parameter set to their DBAdaptor
               equivalent. Group must be defined.

  Returntype : Int count of the DBAdaptor instances which can be found in the 
               registry

  Exceptions : Thrown if the given URL does not parse according to the above 
               scheme and if the specified database cannot be connected to 
               (see load_registry_from_db for more information)
