Member Function Documentation

OZW * instance ( )

static

Get our singleton instance, initializing it if neccessary. All requests to this class should be done through this instance accessor.

Returns

static pointer to our class instance

Here is the caller graph for this function:

void optionsCreate	(	std::string	configPath = "/etc/openzwave",
		std::string	userConfigDir = "",
		std::string	cmdLine = ""
	)

Start configuration with basic options. This must be called prior to init(), after the OZW() constructor is called.

Parameters

configPath	Set the location of the OpenZWave config directory, default is /etc/openzwave
userConfigDir	Set the path to the user configuration directory. This is the location of the zwcfg*.xml and option.xml files for the user (probably created by the OpenZWave Control Panel example application). The default is the current directory ("").
cmdLine	Specify command line formatted options to OpenZWave. The default is "".

Here is the caller graph for this function:

void optionAddInt	(	std::string	name,
		int	val
	)

Add an integer Option. See the OpenZWave documentation for valid values.

Parameters

name	The name of the configuration option
val	The value to set it to

Here is the caller graph for this function:

void optionAddBool	(	std::string	name,
		bool	val
	)

Add a boolean Option. See the OpenZWave documentation for valid values.

Parameters

name	The name of the configuration option
val	The value to set it to

Here is the caller graph for this function:

void optionAddString	(	std::string	name,
		std::string	val,
		bool	append
	)

Add a string Option. See the OpenZWave documentation for valid values.

Parameters

name	The name of the configuration option
val	The value to set it to true to append to the option, false to override

Here is the caller graph for this function:

void optionsLock

(

)

Lock the Options. This must be called after all options have been set, and before init() is called. If init() is called without locking the Options, init() will lock them itself. After the options have been locked, no further options can be specified.

Here is the caller graph for this function:

bool init	(	std::string	devicePath,
		bool	isHID = false
	)

Initialize the ZWave network. This method will start a probe of all defined devices on the ZWave network and query essential information about them. This function will not return until either initialization has failed, or has succeeded far enough along for the following methods to work. Depending on the size an complexity of the ZWave network, this may take anywhere from seconds to several minutes to complete.

All Options (via option*()) must have been specified before this function is called. If the Options have not been locked via optionsLock() prior to calling init(), this method will lock them for you before proceeding.

Parameters

devicePath	The device path for the ZWave controller, typically something like /dev/ttyACM0, or similiar
isHID	true if this is a HID device, false otherwise (ie: a serial port like /dev/ttyACM0, /dev/ttyUSB0, etc). Default is false.

Returns

true if init succeeded, false otherwise

Here is the caller graph for this function:

void dumpNodes

(

bool

all = false

Parameters

all	set to true to dump information about all values available for each node. If false, only information about 'user' values (ignoring 'system' and 'configuration') are output. The default is false ('user' values only).

Here is the caller graph for this function:
