◆ clone_()

template<typename RetT = double, typename ArgT = double, typename fxn_t = RetT (* const)(ArgT)>

virtual UnaryFunction * sparta::statistics::expression::UnaryFunction< RetT, ArgT, fxn_t >::clone_ ( ) const

inlineoverridevirtual

Deep copy of the content of this item.

To be overridden by subclasses

Implements sparta::statistics::expression::ExpressionNode.

Here is the call graph for this function:

◆ dump()

template<typename RetT = double, typename ArgT = double, typename fxn_t = RetT (* const)(ArgT)>

		bool	show_range = true,
		bool	resolve_subexprs = true ) const

inlineoverridevirtual

Dump the content of this expression item.

Note: Must not evaluate the expression

Parameters

o	Ostream to write to
show_range	Should the range be shown in any subexpression nodes.
resolve_subexprs	Should any referenced statistic defs be expanded to their full expressions so that this becomes an expression containing only counters.
