Detailed Description

template<typename T>
class astra_ros::Parameter< T >

A "live" value that can be changed at runtime. Changes are broadcast to a listener.

Parameters can be copied cheaply. They are backed by ParameterImpl, which implements the actual logic.

Constructor & Destructor Documentation

Parameter() [1/2]

template<typename T >

astra_ros::Parameter< T >::Parameter ( )

inline

Create a Parameter with the value T() (the default value for the type T)

Parameter() [2/2]

template<typename T >

astra_ros::Parameter< T >::Parameter ( const T &  value )

inline

Create a Parameter with a given value

Member Function Documentation

bind()

template<typename T >

template<typename F , typename... Args>

static OnChange astra_ros::Parameter< T >::bind ( F &&  f, Args &&...  args  )

inlinestatic

Helper method used by bindOnChangeHandler. Wraps std::bind in an OnChange.

bindOnChangeHandler()

template<typename T >

template<typename F , typename... Args>

void astra_ros::Parameter< T >::bindOnChangeHandler ( F &&  f, Args &&...  args  )

inline

Convience method for setting the OnChange handler with semantics equivalent to std::bind.

get()

template<typename T >

const T& astra_ros::Parameter< T >::get ( ) const

inline

Retrieve the value of the Parameter.

getOnChangeHandler()

template<typename T >

const boost::optional<OnChange>& astra_ros::Parameter< T >::getOnChangeHandler ( ) const

inline

Retrieve the current onChange handler

Returns

boost::none if not set, otherwise the onChange handler

operator*()

template<typename T >

const T& astra_ros::Parameter< T >::operator* ( ) const

inline

Convenience method. Equivalent to get().

set()

template<typename T >

bool astra_ros::Parameter< T >::set ( const T &  value )

inline

Update the value of the Parameter. Changes are broadcast to the OnChange listener.

setOnChangeHandler()

template<typename T >

void astra_ros::Parameter< T >::setOnChangeHandler ( const boost::optional< OnChange > &  on_change )

inline

Set the OnChange handler that is called when values change. This shouldn't be used by the Parameter "client".
