Detailed Description

A Python wrapper around xAOD::RPyEvent.

In order to make the semi-templated functions of xAOD::RPyEvent more convenient to use from PyROOT, the user is supposed to use an instance of this class, and not ROOT.xAOD.RPyEvent directly.

Constructor & Destructor Documentation

__init__()

python.RPyEvent.RPyEvent.__init__

(

self

)

Constructor for the class.

Definition at line 18 of file RPyEvent.py.

    def __init__( self ):
 
        # Forward the call to the base class's constructor:
        ROOT.xAOD.Experimental.RPyEvent.__init__( self )
        return
 

Member Function Documentation

__getitem__()

python.RPyEvent.RPyEvent.__getitem__	(		self,
			key )

Convenient shorthand for retrieving an object.

Definition at line 25 of file RPyEvent.py.

    def __getitem__( self, key ):
        return self.pyRetrieve( key )
 

contains()

python.RPyEvent.RPyEvent.contains	(		self,
			key,
			type )

Convenient version of the base class's contains function.

This function allows the user to, instead of figuring out the exact type name of some C++ type, to rather write code like:

if event.contains( "Electrons", ROOT.xAOD.ElectronContainer_v1 ):

Parameters

key	The string key of the object to check for
type	The type of the object we are looking for

Returns

True if the object is available in the event, False if it's not

Definition at line 42 of file RPyEvent.py.

    def contains( self, key, type ):
        # Determine the class name:
        clname = type.__name__
        if hasattr( type, "__cpp_name__" ):
            clname = type.__cpp_name__
            pass
        # Call the parent class's function:
        return super( RPyEvent, self ).pyContains( key, clname )
 

transientContains()

python.RPyEvent.RPyEvent.transientContains	(		self,
			key,
			type )

Convenient version of the base class's transientContains function.

This function allows the used to, instead of figuring out the exact type name of some C++ type, to rather write code like:

if event.transientContains( "MyElectrons",
ROOT.xAOD.ElectronContainer_v1 ):

Parameters

key	The string key of the object to check for
type	The type of the object we are looking for

Returns

True if the object is available in the event in a modifiable form, False if it's not

Definition at line 66 of file RPyEvent.py.

    def transientContains( self, key, type ):
        # Determine the class name:
        clname = type.__name__
        if hasattr( type, "__cpp_name__" ):
            clname = type.__cpp_name__
            pass
        # Call the parent class's function:
        return super( RPyEvent,
                      self ).pyTransientContains( key, clname )
