◆ doTransform()

template<class T >

void tf2::doTransform	(	const T &	data_in,
		T &	data_out,
		const geometry_msgs::msg::TransformStamped &	transform
	)

The templated function expected to be able to do a transform.

This is the method which tf2 will use to try to apply a transform for any given datatype.

Parameters

data_in	The data to be transformed.
data_out	A reference to the output data. Note this can point to data in and the method should be mutation safe.
transform	The transform to apply to data_in to fill data_out.

This method needs to be implemented by client library developers

◆ getTimestamp() [1/2]

template<class T >

tf2::TimePoint tf2::getTimestamp ( const T & t )

Get the timestamp from data.

Parameters

t	The data input.

Returns: The timestamp associated with the data.

◆ getFrameId() [1/2]

template<class T >

std::string tf2::getFrameId ( const T & t )

Get the frame_id from data.

Parameters

t	The data input.

Returns: The frame_id associated with the data.

template<class P >

std::string tf2::getFrameId ( const tf2::Stamped< P > & t )

◆ toMsg()

template<typename A , typename B >

B tf2::toMsg ( const A & a )

Function that converts from one type to a ROS message type. It has to be implemented by each data type in tf2_* (except ROS messages) as it is used in the "convert" function.

Parameters

a	an object of whatever type

Returns: the conversion as a ROS message

◆ fromMsg()

template<typename A , typename B >

void tf2::fromMsg	(	const A &	,

b	the object to convert to

◆ convert() [1/2]

template<class A , class B >

void tf2::convert	(	const A &	a,

	)

Function that converts any type to any type (messages or not). Matching toMsg and from Msg conversion functions need to exist. If they don't exist or do not apply (for example, if your two classes are ROS messages), just write a specialization of the function.

Parameters

a	an object to convert from
b	the object to convert to

◆ ATTRIBUTE_ALIGNED16()

tf2::ATTRIBUTE_ALIGNED16 ( class )

The QuadWord class is base class for Vector3 and Quaternion. Some issues under PS3 Linux with IBM 2.1 SDK, gcc compiler prevent from using aligned quadword.

tf2::Vector3 can be used to represent 3D points and vectors. It has an un-used w component to suit 16-byte alignment when tf2::Vector3 is stored in containers. This extra component can be used by derived classes (Quaternion?) or by user Ideally, this class should be replaced by a platform optimized TF2SIMD version that keeps the data in registers

Return the yaw, pitch, roll of anything that can be converted to a tf2::Quaternion The conventions are the usual ROS ones defined in tf2/LineMath/Matrix3x3.h

Parameters

a	the object to get data from (it represents a rotation/quaternion)
yaw	yaw
pitch	pitch
roll	roll

◆ getYaw()

template<class A >

double tf2::getYaw ( const A & a )

Return the yaw of anything that can be converted to a tf2::Quaternion The conventions are the usual ROS ones defined in tf2/LineMath/Matrix3x3.h This function is a specialization of getEulerYPR and is useful for its wide-spread use in navigation

Parameters

a	the object to get data from (it represents a rotation/quaternion)
yaw	yaw

◆ getTransformIdentity()

template<class A >

A tf2::getTransformIdentity ( )

Return the identity for any type that can be converted to a tf2::Transform

Returns: an object of class A that is an identity transform
