Detailed Description

template<typename T>
class pixled::conditional::If< T >

pixled If statement.

T denotes the return type of functions returned depending on the condition.

An If statement takes 3 parameters:

• A condition, of type base::Function<bool> (function returning a boolean)
• A then function, of type base::Function<T>, returned when the condition is true
• An else function, of type base::Function<T>, returned when the condition is false

Template Parameters

T	type of Functions returned in the then / else cases

Parameters

bool	condition
T	then function
T	else function

Return values

T	value returned by the then or else function, depending on the condition

Examples

pixled/conditional/conditional.cpp, and pixled/geometry/index.cpp.

Member Function Documentation

operator()()

template<typename T >

T pixled::conditional::If< T >::operator() ( led  l, time  t  ) const

inlineoverridevirtual

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.

Implements pixled::base::Function< T >.
