NAME

Bio::EnsEMBL::Storable

SYNOPSIS

  my $dbID    = $storable_object->dbID();
  my $adaptor = $storable_object->adaptor();
  if ( $storable_object->is_stored($db_adaptor) ) { ... }

DESCRIPTION

This is a storable base class. All objects which are storable in the database should inherit from this class. It provides two getter/setters: dbID() adaptor(). And a is_stored() method that can be used to determine if an object is already stored in a database.

new

  Arg [-ADAPTOR] : Bio::EnsEMBL::DBSQL::BaseAdaptor
  Arg [-dbID]    : database internal id
  Caller         : internal calls
  Description    : create a new Storable object 
  Returntype     : Bio::EnsEMBL::Storable
  Exceptions     : Adaptor not a Bio::EnsEMBL::DBSQL::BaseAdaptor
  Status         : Stable

new_fast

  Arg [1]    : hashref to be blessed
  Description: Construct a new Bio::EnsEMBL::Storable object using the hashref.
               This is a very quick constructor that requires internal knowledge 
               of the class. This is used in speed critical sections of the code
               where many objects need to be created quickly.
  Exceptions : none
  Returntype : Instance of Bio::EnsEMBL::Storable subclass
  Caller     : general, subclass constructors
  Status     : Stable

dbID

  Arg [1]    : int $dbID
  Description: getter/setter for the database internal id
  Returntype : int
  Exceptions : none
  Caller     : general, set from adaptor on store
  Status     : Stable

adaptor

  Arg [1]    : Bio::EnsEMBL::DBSQL::BaseAdaptor $adaptor
  Description: get/set for this objects Adaptor
  Returntype : Bio::EnsEMBL::DBSQL::BaseAdaptor
  Exceptions : none
  Caller     : general, set from adaptor on store
  Status     : Stable

is_stored

  Arg [1]    : Bio::EnsEMBL::DBSQL::DBConnection 
             : or Bio::EnsEMBL::DBSQL::DBAdaptor
  Example    : do_something if($object->is_stored($db));
  Description: Returns true if this object is stored in the provided database.
               This works under the assumption that if the adaptor and dbID are
               set and the database of the adaptor shares the port, dbname and
               hostname with the provided database, this object is stored in
               that database.
  Returntype : 1 or 0
  Exceptions : throw if dbID is set but adaptor is not
               throw if adaptor is set but dbID is not
               throw if incorrect argument is passed
  Caller     : store methods
  Status     : Stable
