[Zope3-checkins] CVS: Zope3/src/zope/component - __init__.py:1.7

[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/component
In directory cvs.zope.org:/tmp/cvs-serv8556/src/zope/component

Modified Files:
	__init__.py 
Log Message:
In prepration for the upcoming interface changes, I added some
new functions for making interface assertions on instances.  

Rather than:

  class C:

     __class_implements__ = I1, I2

use:

  class C:

     classProvides(I1, I2)

rather than:

__implements__ = I1, I2

use:

moduleProvides(I1, I2)

rather than:

someinstance.__implements__ = I1, I2

use:

directlyProvides(I1, I2)

Note that interface assertions on persistent objects should be aboided
since the internal representation will change.

Continue to make assertions about the interfaces that class instances
implement the same way:

  class C:

     __implements__ = I1, I2


I also modified the core software to use the new spellings.
