Constructor & Destructor Documentation

◆ xml_file_handler()

ChimeraTK::xml_file_handler::xml_file_handler ( const std::string & filePath )

The constructor of the class creates a doc pointer depending on the file path.

Parameters

filePath Path to a xml file which you want to read

Definition at line 37 of file xml_file_handler.cpp.

◆ ~xml_file_handler()

ChimeraTK::xml_file_handler::~xml_file_handler ( )

Destructor of the class, frees the document and clean the parser.

Definition at line 144 of file xml_file_handler.cpp.

Member Function Documentation

◆ createDoc()

bool ChimeraTK::xml_file_handler::createDoc ( const std::string & filePath )

This methode set a document pointer to the file it ist given by the file path.

Parameters

filePath Path to a xml file which you want to read

Returns: Returns true if a document is setted, if not it returns false

Definition at line 94 of file xml_file_handler.cpp.

◆ getAttributeValueFromNode()

std::string ChimeraTK::xml_file_handler::getAttributeValueFromNode	(	xmlNode *	node,
		const std::string &	attributeName
	)

static

This methode returns a value of the given attribute from the given node you want to know.

Parameters

node	Node with the attribute of interest
attributeName	Name of the wanted attribute

Returns: Returns a string of the attribute

Definition at line 122 of file xml_file_handler.cpp.

Here is the caller graph for this function:

◆ getContentFromNode()

std::string ChimeraTK::xml_file_handler::getContentFromNode ( xmlNode * node )

static

This methode returns the value between a xml tag.

For example <tagelement>content</tagelement> the returned value ist "content".

Parameters

node	Node with the content of interest

Returns: Returns a string of the inner content

Definition at line 131 of file xml_file_handler.cpp.

Here is the caller graph for this function:

◆ getNodesByName()

std::vector< xmlNodePtr > ChimeraTK::xml_file_handler::getNodesByName	(	xmlNodePtr	startNode,
		const std::string &	nodeName
	)

static

This methode return a list of all nodes with the given name nodeName starting by the given startNode.

Parameters

startNode	Start node, all child nodes will be searched by the given nodeName
nodeName	Is the name of the xml tag, we use to search for

Returns: Returns a list of all pointer from founded child nodes with nodeName

Definition at line 44 of file xml_file_handler.cpp.

Here is the caller graph for this function:

◆ getNodeSet()

xmlXPathObjectPtr ChimeraTK::xml_file_handler::getNodeSet ( const std::string & xPathString )

This methode return a pointer of a xPath element depending of the given xPathString.

Parameters

xPathString A xPath string we seaching for

Returns: Returns a element pointer if some was found, in other cases it will return NULL

Definition at line 56 of file xml_file_handler.cpp.

Here is the caller graph for this function:

◆ isDocSetted()

bool ChimeraTK::xml_file_handler::isDocSetted ( )

This Methode check if a document is currently setted.

Returns: True or false depending if a document is set or not

Definition at line 87 of file xml_file_handler.cpp.

Here is the caller graph for this function:

◆ parseVariablePath()

std::vector< std::string > ChimeraTK::xml_file_handler::parseVariablePath	(	const std::string &	variablePath,
		const std::string &	seperator = `"/"`
	)

static

This methode splitt a given string bey the given seperators.

You can use the seperator as string of seperators like "_/&" all characters will be used as single seperator

Parameters

variablePath	String which you want to seperate by the seperator
seperator	String of, if you want different, seperators, whicht this methode use to split the string

Returns: Returns a vector of every single splitet word
