Bzzz.... bzzz...... bzzz...... That's not the sound of bees. It's the buzz surrounding new, open source Twitter competitor identi.ca. Creator Evan Prodromou sat down at OSCON in front of Linux.com's video camera and explained what identi.ca is all about and why it's suddenly such a hot item that he's been meeting with multiple venture capitalists -- and can be cavalier enough about those meetings that he canceled one to work on some code bugs that were bothering him instead. Code quality might be a reason for some of the buzz, which has resulted in so many stories about identi.ca that we might as well just link to a Google list of them.

Creator(3U) InterViews Reference Manual Creator(3U)NAME
Creator - recreates catalog-managed objects from disk and instantiates component views from their class identifiers
SYNOPSIS
#include <Unidraw/creator.h>
DESCRIPTION
A creator object can reconstruct a catalog-managed object from disk and can instantiate a component view given a class identifier. Gener-
ally only the Catalog class uses the creator to reconstruct objects from disk, but it may be useful for other classes (e.g., the Component
base class) to use the creator to create views of component subjects.
Applications that derive new catalog-managed classes or component views must also derive a subclass of Creator that extends the base class
operations to support the new classes.
PUBLIC OPERATIONS
Creator()
Instantiate an new creator object. The Catalog constructor requires an instance of a creator object, either an instance of the Cre-
ator base class or an instance of an application-specific Creator subclass.
virtual void* Create(
ClassId, istream& in, ObjectMap* objmap, int objid
)
Create an instance of the class corresponding to the given class identifier. Normally this operation will be used by the Catalog
class exclusively. This operation contains a switch statement that calls a CREATE macro for each possible class identifier. The
CREATE macro takes the istream, ObjectMap, and int arguments as parameters; it is not important to understand how the macro uses
these arguments. For example, the entry for the LineComp line component subject class is
case LINE_COMP: CREATE(LineComp, in, objmap, objid);
Derived Creator classes must redefine this operation to include a switch statement for application-specific classes, with the
default case calling the parent class's Create operation.
virtual void* Create(ClassId id)
Create an instance of the view class corresponding to the given view class identifier. This operation is implemented with a set of
consecutive if statements of the form
if (id == <identifier name>) return new <class name>;
For example, the entry for the PostScript external view class identifier for line components is
if (id == PS_LINE) return new PSLine;
Derived Creator classes must redefine this operation to include if statements for application-specific view classes, with the final
statement being a call to the parent classes's Create operation.
