[in]	_filename	Name of the SDF file
[in]	_sdf	Pointer to an SDF object.
[out]	_errors	Parsing errors will be appended to this variable.

Returns: True if successful.

This populates the sdf pointer from a string. If the string is a URDF string it is converted to SDF first. All string are converted to the latest SDF version

Parameters

[in]	_xmlString	XML string to be parsed.
[in]	_sdf	Pointer to an SDF object.
[out]	_errors	Parsing errors will be appended to this variable.

Returns: True if successful.

	)

Populate the SDF values from a string.

This populates the sdf pointer from a string. If the string is a URDF string it is converted to SDF first. All strings are converted to the latest SDF version

Parameters

[in]	_xmlString	XML string to be parsed.
[in]	_sdf	Pointer to an SDF object.

◆ readString() [4/4]

SDFORMAT_VISIBLE bool sdf::v9::readString	(	const std::string &	_xmlString,
		ElementPtr	_sdf
	)

Populate the SDF values from a string.

This populates the sdf pointer from a string. If the string is a URDF string it is converted to SDF first. All strings are converted to the latest SDF version

Parameters

[in]	_xmlString	XML string to be parsed.
[in]	_sdf	Pointer to an sdf Element object.

Returns: True if successful.

◆ readStringWithoutConversion()

SDFORMAT_VISIBLE bool sdf::v9::readStringWithoutConversion	(	const std::string &	_xmlString,
		SDFPtr	_sdf,
		Errors &	_errors
	)

Populate the SDF values from a string without converting to the latest SDF version.

This populates the sdf pointer from a string. If the string is a URDF file it is converted to SDF first. This function does not convert the loaded SDF to the latest version. Use this function with care, as it may prevent loading of DOM objects from this SDF object.

Parameters

[in]	_xmlString	XML string to be parsed.
[in]	_sdf	Pointer to an SDF object.
[out]	_errors	Parsing errors will be appended to this variable.

Returns: True if successful.

◆ recursiveSameTypeUniqueNames()

SDFORMAT_VISIBLE bool sdf::v9::recursiveSameTypeUniqueNames ( sdf::ElementPtr _elem )

Check that all sibling elements of the same type have unique names.

This checks recursively and should check the files exhaustively rather than terminating early when the first duplicate name is found.

Parameters

[in] _elem sdf Element to check recursively.

Returns: True if all contained elements have do not share a name with sibling elements of the same type.

◆ recursiveSiblingUniqueNames()

SDFORMAT_VISIBLE bool sdf::v9::recursiveSiblingUniqueNames ( sdf::ElementPtr _elem )

Check that all sibling elements of the any type have unique names.

This checks recursively and should check the files exhaustively rather than terminating early when the first duplicate name is found.

Parameters

[in] _elem sdf Element to check recursively.

Returns: True if all contained elements have do not share a name with sibling elements of any type.

◆ SDF_DEPRECATED()

class SDFORMAT_VISIBLE sdf::v9::SDF_DEPRECATED ( 9. 2 )

URDF to SDF converter.

This is now deprecated for external usage and will be removed in the next major version of libsdformat. Instead, consider using sdf::readFile or sdf::readString, which automatically convert URDF to SDF.

constructor

destructor

convert urdf xml document string to sdf xml document

Parameters

[in] _xmlDoc a tinyxml document containing the urdf model

Returns: a tinyxml document containing sdf of the model

convert urdf file to sdf xml document

Parameters

[in] _urdfStr a string containing filename of the urdf model

Returns: a tinyxml document containing sdf of the model

convert urdf string to sdf xml document, with option to enforce limits.

Parameters

[in]	_urdfStr	a string containing model urdf
[in]	_enforceLimits	option to enforce joint limits

Returns: a tinyxml document containing sdf of the model

Return true if the filename is a URDF model.

Parameters

[in] _filename File to check.

Returns: True if _filename is a URDF model.

things that do not belong in urdf but should be mapped into sdf

Todo:: : do this using sdf definitions, not hard coded stuff

list extensions for debugging

◆ shouldValidateElement()

SDFORMAT_VISIBLE bool sdf::v9::shouldValidateElement ( sdf::ElementPtr _elem )

Check whether the element should be validated.

If this returns false, validators such as the unique name and reserve name checkers should skip this element and its descendants.

Parameters

[in] _elem sdf Element to check.

Returns: True if the element should be validated

◆ split()

SDFORMAT_VISIBLE std::vector<std::string> sdf::v9::split	(	const std::string &	_str,
		const std::string &	_splitter
	)

Split a string using the delimiter in splitter.

Parameters

[in]	str	The string to split.
[in]	splitter	The delimiter to use.

Returns: A vector of strings containing the split tokens.

◆ trim()

SDFORMAT_VISIBLE std::string sdf::v9::trim ( const char * _in )

Trim leading and trailing whitespace from a string.

Parameters

[in] _in The string to trim.

Returns: A string containing the trimmed value.
