ALPreferenceManager API

NAOqi Core - Overview | API

Namespace : AL

#include <alproxies/alpreferencemanagerproxy.h>

ALPreferenceManager allows managing the robot preferences. A preference is defined by the tuple:

  • Domain of the preference (for instance ‘com.aldebaran.modules.tts’, ‘com.aldebaran.apps.chess’, ...)
  • Name of the preference (for instance ‘/voice/pitch’, ‘/game/level/default’, ...)
  • Value of the preference (only string data type is currently supported)

These preferences are stored on the robot as well as in the Cloud, where they can also be accessed and modified.

Methods

AL::ALValue ALPreferenceManagerProxy::getValue(const std::string& domain, const std::string& name)

Retrieves the value of a preference from its domain and name.

Parameters:

Retrieves all the preferences associated to a domain.

Parameters:
  • domain – Domain of the preference.
Returns:

A list containing couples (list of size 2) of preference names and values (example: [ [“/voice/pitch”, “60”], [“/voice/speed”, “20”] ]).
std::list<string> ALPreferenceManagerProxy::getDomainList()

Retrieves the list of defined preference domains.

Returns:An array of domain names.
void ALPreferenceManagerProxy::importPrefFile(const std::string& domain, const std::string& applicationName, const std::string& filename, bool override)
