RooAbsCategory Class Referenceabstract

A space to attach TBranches.

RooAbsCategory is the base class for objects that represent a discrete value with a finite number of states.

Each state is denoted by an integer and a name. Both can be used to retrieve and set states, but referring to states by index is more efficient. Conversion between index and name can be done using lookupName() or lookupIndex(). It is possible to iterate through all defined states using begin() and end().

For category classes deriving from RooAbsCategory, states can only be evaluated, i.e., queried. Refer to RooAbsCategoryLValue and its derived classes for categories where states can also be set. The simplest category class whose states can be set, queried and saved in a dataset, refer to RooCategory.

Interface change in ROOT-6.22

Category data were based in the class RooCatType, holding an index state and a category name truncated to 256 characters. This wastes 64 bytes of storage space per entry, and prevents fast retrieval of category data. Since ROOT-6.22, categories are only represented by an integer. RooAbsCategory::lookupName() can be used to retrieve the corresponding state name. There is no limit for the length of the state name.

To not break old code, the old RooCatType interfaces are still available. Whenever possible, the following replacements should be used:

Legacy interface

Previous versions of RooAbsCategory were based on RooCatType, a class containing a state and a label.

It has been replaced by integers, which use less space and allow for faster access. The following part of the interface should not be used if possible. Since RooCatType in essence is only an index and a state name, equivalent functionality can be achieved using begin() and end() to iterate through pairs of <index, stateName> and by using using lookupName() and lookupIndex().

const RooCatTypelookupType (value_type index, bool printError=false) const
 Find our type corresponding to the specified index, or return nullptr for no match.
 
const RooCatTypelookupType (const char *label, bool printError=false) const
 Find our type corresponding to the specified label, or return 0 for no match.
 
const RooCatTypelookupType (const RooCatType &type, bool printError=false) const
 Find our type that matches the specified type, or return 0 for no match.
 
TIteratortypeIterator () const
 
Int_t numTypes (const char *=nullptr) const
 Return number of types defined (in range named rangeName if rangeName!=nullptr)
 
Int_t getIndex () const
 Retrieve the current index. Use getCurrentIndex() for more clarity.
 
const char * getLabel () const
 Retrieve current label. Use getCurrentLabel() for more clarity.
 
virtual bool isValid (const RooCatType &value) const
 Check if given state is defined for this object.
 
const RooCatTypedefineType (const char *label)

Shape : label, index, defined types 

Reimplemented from RooAbsArg.

Reimplemented in RooBinningCategory, RooMappedCategory, RooMultiCategory, RooSuperCategory, and RooThresholdCategory.

Definition at line 414 of file RooAbsCategory.cxx.

◆ printValue()

void RooAbsCategory::printValue ( std::ostream &  os) const
overridevirtual

Print value (label name)

Reimplemented from RooPrintable.

Definition at line 401 of file RooAbsCategory.cxx.

◆ readFromStream()

bool RooAbsCategory::readFromStream ( std::istream &  is,
bool  compact,
bool  verbose = false 
)
overridevirtual

Read object contents from stream (dummy for now)

Implements RooAbsArg.

Reimplemented in RooMultiCategory, RooCategory, and RooMappedCategory.

Definition at line 381 of file RooAbsCategory.cxx.

◆ recomputeShape()

virtual void RooAbsCategory::recomputeShape ( )
protectedpure virtual

If a category depends on the shape of others, i.e. its state numbers or names depend on the states of other categories, this function has to be implemented to recompute _stateNames and _insertionOrder.

If one of these two changes, setShapeDirty() has to be called to propagate this information to possible users of this category.

Implemented in RooBinningCategory, RooCategory, RooMappedCategory, RooMultiCategory, RooSuperCategory, and RooThresholdCategory.

◆ retrieveLegacyState()

RooCatType * RooAbsCategory::retrieveLegacyState ( value_type  index) const
protected

Return the legacy RooCatType corresponding to index. If it doesn't exist, create one.

Definition at line 698 of file RooAbsCategory.cxx.

◆ setCachedValue()

void RooAbsCategory::setCachedValue ( double  value,
bool  notifyClients = true 
)
finalprotectedvirtual

Overwrite the value stored in this object's cache.

This can be used to fake a computation that resulted in value.

Parameters
[in]valueValue to write. The argument is reinterpreted as a category state. If such a state does not exist, this will create undefined behaviour.
[in]notifyClientsIf true, notify users of this object that its value changed. This is the default.

Reimplemented from RooAbsArg.

Definition at line 580 of file RooAbsCategory.cxx.

◆ setTreeBranchStatus()

void RooAbsCategory::setTreeBranchStatus ( TTree t,
bool  active 
)
overrideprotectedvirtual

(De)activate associate tree branch

Implements RooAbsArg.

Definition at line 534 of file RooAbsCategory.cxx.

◆ size()

std::size_t RooAbsCategory::size ( ) const
inline

Number of states defined.

Definition at line 99 of file RooAbsCategory.h.

◆ stateNames() [1/2]

std::map< std::string, value_type > & RooAbsCategory::stateNames ( )
inlineprotected

Access the map of state names to index numbers.

Triggers a recomputation if the shape is dirty.

Definition at line 168 of file RooAbsCategory.h.

◆ stateNames() [2/2]

const std::map< std::string, value_type > & RooAbsCategory::stateNames ( ) const
inlineprotected

Access the map of state names to index numbers.

Triggers a recomputation if the shape is dirty.

◆ syncCache()

void RooAbsCategory::syncCache ( const RooArgSet set = nullptr)
overrideprotectedvirtual

Explicitly synchronize RooAbsCategory internal cache.

Implements RooAbsArg.

Definition at line 547 of file RooAbsCategory.cxx.

◆ typeIterator()

TIterator * RooAbsCategory::typeIterator ( ) const
Deprecated:
Use begin() and end() instead.
Note
Using this iterator creates useless RooCatType instances, which will leak unless deleted by the user.

Definition at line 678 of file RooAbsCategory.cxx.

◆ writeToStream()

void RooAbsCategory::writeToStream ( std::ostream &  os,
bool  compact

Write object contents to ostream.
