RooAbsArg Class Reference

Common abstract base class for objects that represent a value and a "shape" in RooFit.

Values or shapes usually depend on values or shapes of other RooAbsArg instances. Connecting several RooAbsArg in a computation graph models an expression tree that can be evaluated.

Building a computation graph of RooFit objects

Therefore, RooAbsArg provides functionality to connect objects of type RooAbsArg into a computation graph to pass values between those objects. A value can e.g. be a real-valued number, (instances of RooAbsReal), or an integer, that is, category index (instances of RooAbsCategory). The third subclass of RooAbsArg is RooStringVar, but it is rarely used.

The "shapes" that a RooAbsArg can possess can e.g. be the definition range of an observable, or how many states a category object has. In computations, values are expected to change often, while shapes remain mostly constant (unless e.g. a new range is set for an observable).

Nodes of a computation graph are connected using instances of RooAbsProxy. If Node B declares a member RooTemplateProxy<TypeOfNodeA>, Node A will be registered as a server of values to Node B, and Node B will know that it is a client of node A. Using functions like dependsOn(), or getObservables() / getParameters(), the relation of A --> B can be queried. Using graphVizTree(), one can create a visualisation of the expression tree.

An instance of RooAbsArg can have named attributes. It also has flags to indicate that either its value or its shape were changed (= it is dirty). RooAbsArg provides functionality to manage client/server relations in a computation graph (clientServerInterface), and helps propagating value/shape changes through the graph. RooAbsArg implements interfaces for inspecting client/server relationships (clientServerInterface) and setting/clearing/querying named attributes.

Caching of values

The values of nodes in the computation graph are cached in RooFit. If a value is used in two nodes of a graph, it doesn't need to be recomputed. If a node acquires a new value, it notifies its consumers ("clients") that their cached values are dirty. See the functions in optimisationInterface for details. A node uses its isValueDirty() and isShapeDirty() functions to decide if a computation is necessary. Caching can be vetoed globally by setting a bit using setDirtyInhibit(). This will make computations slower, but all the nodes of the computation graph will be evaluated irrespective of whether their state is clean or dirty. Using setOperMode(), caching can also be enabled/disabled for single nodes.

Obtain an estimate of the number of parameters of the function and its daughters.

Calling addParameters for large functions (NLL) can cause many reallocations of params due to the recursive behaviour.

recursiveRedirectServers()

bool RooAbsArg::recursiveRedirectServers	(	const RooAbsCollection &	newServerList,
		bool	mustReplaceAll = false,
		bool	nameChange = false,
		bool	recurseInNewSet = true
	)

Recursively replace all servers with the new servers in newSet.

This substitutes objects that we receive values from (also indirectly through other objects) with new objects that have the same name.

Copied from redirectServers:

This substitutes objects that we receive values from with new objects that have the same name.

See also

recursiveRedirectServers() Use recursive version if servers that are only indirectly serving this object should be replaced as well.

redirectServers() If only the direct servers of an object need to be replaced.

Note that changing the types of objects is generally allowed, but can be wrong if the interface of an object changes. For example, one can reparametrise a model by substituting a variable with a function:

\[ f(x\, |\, a) = a \cdot x \rightarrow f(x\, |\, b) = (2.1 \cdot b) \cdot x \]

If an object, however, expects a PDF, and this is substituted with a function that isn't normalised, wrong results might be obtained or it might even crash the program. The types of the objects being substituted are not checked.

Parameters

[in]	newSetOrig	Set of new servers that should be used instead of the current servers.
[in]	mustReplaceAll	A warning is printed and error status is returned if not all servers could be substituted successfully.
[in]	nameChange	If false, an object named "x" is only replaced with an object also named "x" in newSetOrig. If the object in newSet is called differently, set nameChange to true and use setAttribute() on the x object: objectToReplaceX.setAttribute("ORIGNAME:x") Now, the renamed object will be selected based on the attribute "ORIGNAME:<name>".
[in]	isRecursionStep	Internal switch used when called from recursiveRedirectServers().
	newSet	Roo collection
	recurseInNewSet	be recursive

redirectServersHook()

bool RooAbsArg::redirectServersHook ( const RooAbsCollection &  newServerList, bool  mustReplaceAll, bool  nameChange, bool  isRecursiveStep  )

virtual

Function that is called at the end of redirectServers().

Can be overloaded to inject some class-dependent behavior after server redirection, e.g. resetting of caches. The return value is meant to be an error flag, so in case something goes wrong the function should return true. If you overload this function, don't forget to also call the function of the base class.

registerCache()

void RooAbsArg::registerCache

(

RooAbsCache &

cache

)

Register RooAbsCache with this object.

This function is called by RooAbsCache constructors for objects that are a datamember of this RooAbsArg. By registering itself the RooAbsArg is aware of all its cache data members and will forward server change and cache mode change calls to the cache objects, which in turn can forward them their contents

replaceServer()

void RooAbsArg::replaceServer	(	RooAbsArg &	oldServer,
		RooAbsArg &	newServer,
		bool	propValue,
		bool	propShape
	)

Replace 'oldServer' with 'newServer', specifying whether the new server has value or shape server properties.

Warning

This function should not be used! This method is quite unsafe for many reasons. For once, the new server will be put at the end of the server list, no matter the position of the original server. This might mess up code that expects the servers to be in a certain order. Furthermore, the proxy objects corresponding to the server are not updated, leaving the object in an invalid state where the servers are out of sync with the proxies. This can have very bad consequences. Finally, by having to manually specify the value and shape server properties, it is very easy to get them wrong.

If you want to safely replace a server, you should use RooAbsArg::redirectServers(), which replaces the server in-place at the same position of the server list, keeps the same value and shape server properties, and also updates the corresponding proxies.
