Detailed Description

template<typename T>
class drake::systems::Adder< T >

An adder for arbitrarily many inputs of equal length.

Template Parameters

T	The type of mathematical object being added.

Constructor & Destructor Documentation

Adder	(	int	num_inputs,
		int	length
	)

Parameters

num_inputs	is the number of input ports to be added.
length	is the size of each input port.

Member Function Documentation

std::unique_ptr< SystemOutput< T > > AllocateOutput ( ) const

overridevirtual

Allocates one output port of the width specified in the constructor.

Implements SystemInterface< T >.

std::unique_ptr< Context< T > > CreateDefaultContext ( ) const

overridevirtual

Allocates the number of input ports specified in the constructor.

Allocates no state.

Implements SystemInterface< T >.

void EvalOutput ( const Context< T > &  context, SystemOutput< T > *  output  ) const

overridevirtual

Sums the input ports into the output port.

If the input ports are not of number num_inputs_ or size length_, std::runtime_error will be thrown.

Implements SystemInterface< T >.

Here is the call graph for this function:

std::string get_name ( ) const

inlineoverridevirtual

TODO(david-german-tri): Make this configurable in the constructor.

Implements AbstractSystemInterface.
