Detailed Description

Provide to_json() and from_json() overloads for simox::json::json, which allows simple syntax like:

Eigen::Matrix3f in, out;

simox::json::json j;
j = in;
out = j.get<Eigen::Matrix3f>();

Test:

VirtualRobotJsonEigenConversionTest

Function Documentation

from_json() [1/3]

template<typename Derived >

void Eigen::from_json	(	const simox::json::json &	j,
		Eigen::MatrixBase< Derived > &	matrix
	)

Reads the matrix from list of rows.

from_json() [2/3]

template<typename Derived >

void Eigen::from_json	(	const simox::json::json &	j,
		Eigen::QuaternionBase< Derived > &	quat
	)

Reads the quaternion from qw, qx, qy, qz keys.

from_json() [3/3]

template<typename T , int N, int Type>

void Eigen::from_json	(	const simox::json::json &	j,
		Eigen::Transform< T, N, Type > &	transform
	)

from_json< Eigen::Matrix4f >() [1/2]

template<>

void Eigen::from_json< Eigen::Matrix4f >	(	const ::simox::json::json &	j,
		Eigen::MatrixBase< Eigen::Matrix4f > &	matrix
	)

from_json< Eigen::Matrix4f >() [2/2]

template<>

void Eigen::from_json< Eigen::Matrix4f >	(	const simox::json::json &	j,
		Eigen::MatrixBase< Eigen::Matrix4f > &	matrix
	)

Reads a 4x4 matrix from list of rows or pos and ori keys.

If j is an object, reads matrix as transformation matrix from pos and ori keys. Otherweise, reads it from list of rows.

from_json< Eigen::Vector3f >() [1/2]

template<>

void Eigen::from_json< Eigen::Vector3f >	(	const ::simox::json::json &	j,
		Eigen::MatrixBase< Eigen::Vector3f > &	vector
	)

from_json< Eigen::Vector3f >() [2/2]

template<>

void Eigen::from_json< Eigen::Vector3f >	(	const simox::json::json &	j,
		Eigen::MatrixBase< Eigen::Vector3f > &	vector
	)

If j is an object, reads vector from x, y, z keys. Otherwise, reads it as matrix.

to_json() [1/3]

template<typename Derived >

void Eigen::to_json	(	simox::json::json &	j,
		const Eigen::MatrixBase< Derived > &	matrix
	)

Writes the matrix as list of rows.

to_json() [2/3]

template<typename Derived >

void Eigen::to_json	(	simox::json::json &	j,
		const Eigen::QuaternionBase< Derived > &	quat
	)

Writes the quaternion with qw, qx, qy, qz keys.

to_json() [3/3]

template<typename T , int N, int Type>

void Eigen::to_json	(	simox::json::json &	j,
		const Eigen::Transform< T, N, Type > &	transform
	)
