Oryx::Association(3) User Contributed Perl Documentation Oryx::Association(3) NAME Association - abstract base class for Association types SYNOPSIS my $assoc = Oryx::Association->new($meta, $source); $assoc->source; # association from $assoc->class; # association to $assoc->role; # name of association accessor $assoc->type; # Array, Hash, Reference etc. $assoc->constraint; # Aggregate or Composition $assoc->is_weak; $assoc->update_backrefs; $assoc->link_table; DESCRIPTION This module represents an abstract base class for Oryx association types. METHODS new( $meta, $source ) The constructor returns the correct instance of the correct subclass based on the "type" field of the $meta hashref passed as an argument. The $source argument is the name of the class in which this association is defined (see Oryx::Class) create Abstract (see implementing subclasses) retrieve Abstract (see implementing subclasses) update Abstract (see implementing subclasses) delete Abstract (see implementing subclasses) search Abstract (see implementing subclasses) construct Abstract (see implementing subclasses) source Simple accessor to the source class in which this association is defined. class Simple accessor to the target class with which the source class has an associtation. role Simple accessor to the association accessor name defined in the source class. Defaults to the target class' table name. type Reference, Array or Hash... defaults to Reference. is_weak Simple accessor to the "is_weak" meta-attribute. This is used for stopping Reference association types from creating a column in the target class for storing a reverse association. constraint Simple accessor to the "constraint" meta-attribute. Values are: Aggregate or Composition ... Aggregate is the default, Composition causes deletes to cascade. update_backrefs Updates reverse Reference associations. NOTE: Currently, reverse associations are made up of two unidirectional associations... link tables are therefore not shared. This will be fixed. link_table Returns a name for the link table for this association. Not relevant for Reference associations as these don't require a link table. This is just a shortcut for: $self->source->table.'_'.$self->role.'_'.$self->class->table Override for custom association types as needed.
