class mrpt::config::CConfigFileMemory

This class implements a config file-like interface over a memory-stored string list.

Use base class CConfigFileBase ‘s methods read_{int,float,double,string,...}() and write() to actually read and write values.

It can also parse a YAML text block and expose its fields (up to the first level of hierarchy, as allowed by INI-like files). This can be used to port MRPT classes relying on INI files to using YAML files transparently. This feature required building MRPT with yaml-cpp, and is provided by CConfigFileMemory::setContentFromYAML().

See: Configuration file format in MRPT

YAML support was introduced in MRPT 1.9.9

Construction

CConfigFileMemory()

Empty constructor.

Upon construction, call any of the “setContent” method

CConfigFileMemory(const std::vector<std::string>& stringList)

Constructor and initialize from a list of strings.

CConfigFileMemory(const std::string& str)

Constructor and initialize from string with the whole “config file”.

Methods

void setContent(const std::vector<std::string>& stringList)

Changes the contents of the virtual “config file”.

void setContent(const std::string& str)

Changes the contents of the virtual “config file”.

void getContent(std::string& str) const

Return the current contents of the virtual “config file”.

std::string getContent() const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

virtual void clear()

Empties the virtual “config file”.

virtual void getAllSections(std::vector<std::string>& sections) const

Returns a list with all the section names.

virtual void getAllKeys(
    const std::string& section,
    std::vector<std::string>& keys
    ) const

Returs a list with all the keys into a section.
