Bio::Biblio::BiblioBase - an abstract base for other biblio classes


version 1.70


 # do not instantiate this class directly


It is a base class where all other biblio data storage classes inherit from. It does not reflect any real-world object, it exists only for convenience, in order to have a place for shared code.


All attribute names can be used as method names. When used without any parameter the method returns current value of the attribute (or undef), when used with a value the method sets the attribute to this value and also returns it back. The set method also checks if the type of the new value is correct.

Custom classes

If there is a need for new attributes, create your own class which usually inherits from Bio::Biblio::Ref. For new types of providers and journals, let your class inherit directly from this Bio::Biblio::BiblioBase class.



The new() class method constructs a new biblio storage object. It accepts list of named arguments - the same names as attribute names prefixed with a minus sign. Available attribute names are listed in the documentation of the individual biblio storage objects.



This method should not be called here; it should be implemented by a subclass

Deal with 'set_' and 'get_' methods


Set methods test whether incoming value is of a correct type; here we return message explaining it

Probably just for debugging TBD: to decide...


Mailing lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.                  - General discussion  - About the mailing lists


Please direct usage questions or support issues to the mailing list:

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
