Detailed Description

template<typename R>
class pixled::base::Function< R >

Generic Function interface, that can be used as arguments for other Functions.

Notice that Function parameters are voluntarily not fixed in this base class. This allows Functions to be used as other Functions parameters, since when a Function is passed as a parameter, the only thing that matters is its return type, that can actually be considered as the type of the parameter.

Template Parameters

R	return type

Type

template<typename R >

typedef R pixled::base::Function< R >::Type

Function return type.

Member Function Documentation

operator()()

template<typename R >

virtual R pixled::base::Function< R >::operator() ( led  l, time  t  ) const

pure virtual

Computes the value of this Function for led l at time t.

Parameters

l	led
t	time

Returns

Result of this Function, evaluated on led l at time t. Notice that evaluating a function usually requires the recursive evaluation of other Functions (that are actually parameters of this function) until a Constant is reached for example.
