fv Namespace Reference

The namespace containing all filval classes and functions. More...

Classes
class	Apply< Ret(ArgTypes...)>
	Applies a function to a tuple of values and returns a value. More...
class	BoundValue
	A generic value owning only a function object. More...
class	CartProduct
	Find and return the minimum value of a vector and its index. More...
class	ConstantValue
	A Value which always returns the same value, supplied in the constructor. More...
class	Container
	A class that is used to "hold" values. More...
class	ContainerMean
	Calculate the Mean of a Value over a series of observations. More...
class	Count
	Returns the count of elements in the input vector passing a test function. More...
class	DerivedValue
	A Value derived from some other Values, not directly from the dataset. More...
class	ElementOf
	Extract the element at a specific index from a vector. More...
class	Filter
	Returns the elements in a vector that pass a test function. More...
class	Function< R(ArgTypes...)>
	In order to enable proper provenance tracking, and at the same time keep the ability to embed functions into values, the Function class should be used. More...
class	GenContainer
	Generic, untyped parent class of Container. More...
class	GenFunction
	Parent class to all Function classes. More...
class	Map< Ret(ArgTypes...)>
	Maps a function over an input vector. More...
class	Max
	Find and return the maximum value of a vector. More...
class	MaxIndex
	Find and return the maximum value of a vector and its index. More...
class	Mean
	Calculate the mean value of a vector. More...
class	Min
	Find and return the minimum value of a vector. More...
class	MinIndex
	Find and return the minimum value of a vector and its index. More...
class	ObservedValue
	A value supplied by the dataset, not derived. More...
class	Pair
	Creates a std::pair type from a two other Value objects. More...
class	PointerValue
	A Value of a pointer. More...
class	Range
	Calculate the range of the values in a vector. More...
class	Reduce
	Reduce a Value of type vector<T> to just a T. More...
class	ReduceIndex
	Similar to Reduce, but returns a pair of a T and an int. More...
class	TupFilter
	Returns the elements in a vector that pass a test function. More...
class	Tuple
	Takes a series of Value objects and bundles them together into a std::tuple object. More...
class	Value
	A generic value. More...
class	WrapperVector
	A std::vector wrapper around a C-style array. More...
class	Zip
	Zips a series of vectors together. More...

Detailed Description

The namespace containing all filval classes and functions.

Enumeration Type Documentation

SaveOption

enum fv::SaveOption

Enumeration of different options that can be used to save Containers.

Not all options are allowed for all Containers.

Function Documentation

call()

template<typename F , typename TUPLE >

auto fv::call	(	F &	f,
		TUPLE &&	t
	)

This calls a function of type F with the contents of the tuple as separate arguments.
