Public Member Functions

	getComp (self, classname)

Public Attributes
str	prefix = "" else ""

Detailed Description

A namespace able to automatically generate Configured when quering attributes :
Used to replace CompFactory so that expressions like :
  tool = CompFactory.Trk.SomeTrkTool("tname", Prop=2.345) 
  tool = CompFactory.getComp("Trk::SomeTrkTool")("tname", Prop=2.345) 
works. 
In the above 2 examples both CompFactory and Trk are ConfNameSpace

__getattr__()

# ----------------------------
# A replacement for CompFactory

getComp()

python.JetAnalysisCommon.ConfNameSpace.getComp	(		self,
			classname )

generates a new Configured class for the C++ class ROOT.classname .
 This implies there must be a dictionnary for classname.
