◆ copyCache()

void RooStringVar::copyCache	(	const RooAbsArg *	source,
		bool	valueOnly = `false`,
		bool	setValDirty = `true`
	)

overrideprotectedvirtual

Copy cache of another RooAbsArg to our cache.

Warning: This function copies the cached values of source, it is the callers responsibility to make sure the cache is clean

Implements RooAbsArg.

Definition at line 88 of file RooStringVar.cxx.

◆ createFundamental()

RooFit::OwningPtr< RooAbsArg > RooStringVar::createFundamental ( const char * newname = nullptr ) const

inlineoverridevirtual

Create a fundamental-type object that stores our type of value.

The created object will have a valid value, but not necessarily the same as our value. The caller is responsible for deleting the returned object.

Implements RooAbsArg.

Definition at line 56 of file RooStringVar.h.

◆ DeclFileName()

static const char * RooStringVar::DeclFileName ( )

inlinestatic

Returns: Name of the file containing the class declaration

bool RooStringVar::isFundamental ( ) const

inlineoverridevirtual

Is this object a fundamental type that can be added to a dataset? Fundamental-type subclasses override this method to return true.

Note that this test is subtlely different from the dynamic isDerived() test, e.g. a constant is not derived but is also not fundamental.
