RMergeableVariations() [1/4]

template<typename T>

ROOT::Detail::RDF::RMergeableVariations< T >::RMergeableVariations ( )

default

Default constructor.

Needed to allow serialization of ROOT objects. See [TBufferFile::WriteObjectClass] (classTBufferFile.html::a209078a4cb58373b627390790bf0c9c1)

RMergeableVariations() [4/4]

template<typename T>

ROOT::Detail::RDF::RMergeableVariations< T >::RMergeableVariations ( RMergeableVariationsBase && base )

inline

Constructor that initializes data members.

Parameters

[in]

base

The container of the names and values.

The variation names and values are moved from the base container into this.

Definition at line 723 of file RMergeableValue.hxx.

Member Function Documentation

AddNominal()

void ROOT::Detail::RDF::RMergeableVariationsBase::AddNominal ( std::unique_ptr< RMergeableValueBase > value )

inlineinherited

Add an entry for the "nominal" value.

The way client code is structured, the nominal value is provided separately from the others.

Definition at line 663 of file RMergeableValue.hxx.

GetKeys()

template<typename T>

const std::vector< std::string > & ROOT::Detail::RDF::RMergeableVariations< T >::GetKeys ( ) const

inline

Get the list of variation names.

Definition at line 727 of file RMergeableValue.hxx.

GetVariation()

template<typename T>

const T & ROOT::Detail::RDF::RMergeableVariations< T >::GetVariation ( const std::string & variationName ) const

inline

Get the final value from the mergeable corresponding to a certain variation name.

Parameters

[in]

variationName

The name.

The variation name is used to retrieve the corresponding RMergeableValue contained in this object. From that, the actual value is retrieved by calling the ROOT::Detail::RDF::RMergeableValue::GetValue function.

Definition at line 736 of file RMergeableValue.hxx.

Merge()

template<typename T>

void ROOT::Detail::RDF::RMergeableVariations< T >::Merge ( const RMergeableVariations< T > & other )

inlineprivate

Aggregate the information contained in another RMergeableVariations into this.

Parameters

[in]

other

The other mergeable.

Iterates over all values of the current object and calls ROOT::Detail::RDF::MergeValues to merge with the corresponding value of the other object.

Note

All the Merge methods in the RMergeableValue family are private. To merge multiple RMergeableValue objects please use ROOT::Detail::RDF::MergeValues
