bool	sameType (Value val)
	checks whether or not the raw value stored in the value is compatible with the given parameter. Compatible is a very broad word in this scenario. It means that the value can be placed in the parameter regardless of other limitations.

Detailed Description

a double implementation of the parameter. This is used to handle double-precision floating point numbers, though it can handle single precision as well.

Constructor & Destructor Documentation

ddynamic_reconfigure::DDDouble::DDDouble	(	const string &	name,
		unsigned int	level,
		const string &	description,
		double	def,
		double	min = `-d_limit::infinity()`,
		double	max = `d_limit::infinity()`
	)		`[inline]`

creates a new double param

Parameters:

name	the name of the parameter
level	the change level
def	the default value
description	details about the parameter
max	the maximum allowed value. Defaults to DBL_MAX
min	the minimum allowed value. Defaults to -DBL_MAX

Member Function Documentation

int ddynamic_reconfigure::DDDouble::getLevel ( ) const [virtual]

fetches the level of the parameter

Returns:: the level of the param.

Implements ddynamic_reconfigure::DDParam.

Definition at line 39 of file dd_double_param.cpp.

string ddynamic_reconfigure::DDDouble::getName ( ) const [virtual]

gets the name of the parameter, that is, the ID used in the program when requesting it.

Returns:: the unique string name of the parameter.

Implements ddynamic_reconfigure::DDParam.

Definition at line 8 of file dd_double_param.cpp.

Value ddynamic_reconfigure::DDDouble::getValue ( ) const [virtual]

gets the value of this parameter.

Returns:: the value stored in this param.

Implements ddynamic_reconfigure::DDParam.

Definition at line 55 of file dd_double_param.cpp.

void ddynamic_reconfigure::DDDouble::prepConfig ( Config & conf ) [virtual]

updates a config message according to this param's info.

Parameters:

conf	the group to update.

Note:: this is an internal method. It is recommended not to use it.

Implements ddynamic_reconfigure::DDParam.

Definition at line 21 of file dd_double_param.cpp.

void ddynamic_reconfigure::DDDouble::prepConfigDescription ( ConfigDescription & conf_desc ) [virtual]

updates a config description message according to this param's info.

Parameters:

conf_desc the config description to update.

Note:: this is an internal method. It is recommended not to use it.

Implements ddynamic_reconfigure::DDParam.

Definition at line 28 of file dd_double_param.cpp.

void ddynamic_reconfigure::DDDouble::prepGroup ( Group & group ) [virtual]

updates a group message according to this param's info.

Parameters:

group the group to update.

Note:: this is an internal method. It is recommended not to use it.

Implements ddynamic_reconfigure::DDParam.

Definition at line 12 of file dd_double_param.cpp.

bool ddynamic_reconfigure::DDDouble::sameType ( Value val ) [virtual]

checks whether or not the raw value stored in the value is compatible with the given parameter. Compatible is a very broad word in this scenario. It means that the value can be placed in the parameter regardless of other limitations.

Parameters:

val	the value to test

Returns:: true is this parameter can handle the original value, false otherwise.

Implements ddynamic_reconfigure::DDParam.

Definition at line 43 of file dd_double_param.cpp.

bool ddynamic_reconfigure::DDDouble::sameValue ( Value val ) [virtual]

checks whether or not the value stored in the value object, when converted to the type of the internal value, are equal. This acts regardless of type.

Parameters:
