RooAbsCategoryLValue is the common abstract base class for objects that represent a discrete value that can be set from the outside, i.e.

that may appear on the left hand side of an assignment ("*lvalue*").

Each implementation must provide the functions setIndex()/setLabel() to allow direct modification of the value. RooAbsCategoryLValue may be derived, but its functional relation to other RooAbsArgs must be invertible.

void RooAbsCategoryLValue::copyCache	(	const RooAbsArg *	source,
		Bool_t	valueOnly = `kFALSE`,
		Bool_t	setValDirty = `kTRUE`

protectedvirtual

Copy the cached value from given source and raise dirty flag.

It is the callers responsability to ensure that the sources cache is clean(valid) before this function is called, e.g. by calling syncCache() on the source.

Reimplemented from RooAbsCategory.

◆ isLValue()

virtual Bool_t RooAbsCategoryLValue::isLValue ( ) const

inlinevirtual

Is this argument an l-value, i.e., can it appear on the left-hand side of an assignment expression? LValues are also special since they can potentially be analytically integrated and generated.
