◆ Merge()

void ROOT::Detail::RDF::RMergeableCount::Merge ( const RMergeableValue< ULong64_t > &  other)

Aggregate the information contained in another RMergeableValue into this.

[in]otherAnother RMergeableValue object.
std::invalid_argumentIf the cast of the other object to the same type as this one fails.

The other RMergeableValue object is cast to the same type as this object. This is needed to make sure that only results of the same type of action are merged together. Then the two results are added together to update the value held by the current object.

All the Merge methods in the RMergeableValue family are private. To merge multiple RMergeableValue objects please use [MergeValues] (namespaceROOT_1_1Detail_1_1RDF.html::af16fefbe2d120983123ddf8a1e137277).
